I believe your choice of the MZ201/2 will be a good one.  My only 

reservation is the single diaphram carb. The MZ201 is just the MZ202 with a 
	


different intake manifold and Tillotson carb plus limit the rpm to 4800rpm.  

I used many of those carbs over the years and don't consider them reliable 

enough to fly with. Too much fiddling required as per Jack Harts blog, 

thanks Jack. If you could make a single carb manifold and use a Bing or 

Mikuni float style then you would be safer to fly.

Dennis,



One of the things I discovered in adding air/fuel mixture controls to the 

Bing and the Tillotson carburetors is that it seems to calm things down.  By 

that I mean one can set it and change AOA with no throttle change and the 

EGT remains pretty much constant.  I believe the reason for such good 

results are due to the air pressure over the float bowl and under the 

control diaphragm is held constant, where the non controlled vents are 

subjected the pressure environment at the engine.  In a pusher the air is 

being sucked into the propeller and so the carburetor vents see different 

pressures that are a combination of propeller/engine speed, relative wind, 

and altitude.  By connecting the vent to a tube and bringing it into the 

cockpit area to a true static pressure port, the speed and relative wind 

influence portions are removed.  I wish I had thought of this with the 

Rotax 447.  



I had problems with the Tillotson, but after receiving good information for 

initial setup, it seems to be quite stable.  I like being able to prime it 

and to draw fuel up to the carburetor with a simple push bulb.  One must 

balance out the low and high speed needles to maintain a flat EGT over the 

throttle range.  Once this is done, one can prime the engine and the engine 

will start with the throttle closed.  A huge plus for this carburetor is 

that one does not have to open the carburetor to change jets and needles and 

it comes with fuel pump built in.



The only real problem with the Tillotson carburetor is the same as with the 

Bing, carburetor ice.  I have fitted a stud heater to the bottom engine side 

of the Tillotson to try and compensate for the problem.  I have not had a 

chance to check it out.



I have been fortunate in that I mounted the MZ 34 inverted so that the 

carburetor needles can be accessed from the front.  This allowed me to 

attach extension tubes to the needles and to manipulate them with the engine 

running and the FireFly tied down.  It would be great if Tillotson would 

build a mirror image carburetor so that the same could be said for an 

upright engine.



At this point I will take the Tillotson over the Bing, but it is going to 

take another season of flying to see it that holds true.

I ordered a firefly quick build 2 weeks ago, and I have yet to decide which engine I am going to use.



I am considering using a mz201 because of the dual ignition and less weight than the 447.



Does anyone use this engine on a pusher, or know of anyone that has some hours experience with the engine.



I was told by someone to just go with a 503 because of the dual ignition, so I talked with Travis at kolb about it and He said guys have put 503's on firefly's , but I probably won't stay under the legal weight for an ultralight.



So I need to hear some more pro and cons about the mz201 .

Michael, I am in the same boat you are have a Firefly half built and I flew a firestar with a 503 for 10 years trouble free and I am fond of the dual spark Travis tells mre they are working on an engine mount for a  mz 201 ,  maybe for you but the engine sounds good weight wise and power wise I have been looking for someone that has been using it for about a month with no luck ! its expensive but so are the 447 and the 503 ! I am trying to save weight as I will need extra controls as I cant use my feet . Stay in touch, Im here every day . Chris

I have so far arrived at the following weights. I will verify these against another scale soon. I will be able to speak more informatively on engine and exhaust mounting in the coming weeks. The belt reduc is indeed 1.77:1 - two crank rotations gave ~406 degrees on the PTO and one PTO rotation gave ~636 degrees on the crank.

http://phactor.com/Kolb/201/201.htm

 

I do not have weights for the following, yet.

prop (wooden TN 60x24 x 1.75hub on order - (931) 455-4516 - talk to Steve!)

prop crush plate

prop bolts

12v battery

engine mounting plate + bolts

muffler mounting h/w + bolts

Thank you for posting the pictures,The engine looks great!

I guess you are going without the cooling fan and shroud, would it be possible to mount the cooling fan on later if needed?

I won't get my firefly quick build for a couple months yet,So I hope you keep us updated on your progress!

I don't know if you can have all three: pull starter, electric starter, and fan/shroud. My mz201 has pull and elec starter, but no fan/shroud. The mz202 has electric start and fan/shroud. But my old Rotax 503 had pull starter and fan/shroud. Anyone know?

 

You should be able to make any mods you want after-the-fact, assuming they'll fit (see first paragraph), you've left room around your aileron push-pull linkages, exhaust system, etc., and you have the $bucks.

 Ok guys and gals  ya'all got me thinking.... I know next to nothing about the MZ engines and have been seriously considering a re-power of my DCDI-503 powered FSII simply because the engine has very near 300 hours TT.  NOW,  when I posted that I was considering a Hirth some of you got all abrasive    Is, in your opinion, the MZ a better/same/worse choice than the Hirth?  Or do you die hard Rotax folks think I am simply better off having the 503 rebuilt and sticking with what I have???    I am not trying to rock the boat again just wondering how the MZ compares to the Hirth and the Rotax?

I decided on the mz201 for my Firefly. I only know what I've studied online about Simonini, Hirth, Rotax (used to own a 503 on my past Twinstar), and the mz line. I will know a lot more once I get my Firefly built and start running my mz201 on it (in the Spring).

 

My mz201 weighs in at 75lbs total fly-weight without the mounting plates and h/w for the engine and exhaust system, but including everything else; belt reduc, air filter, carb, muffler, elec and pull starters, all ignition components (harness, dual CDI, dual plugs). I thought it would weigh a few pounds less, but as far as I can tell, this is still 15-19 lbs less than the 447, with 4-5 HP more.

I really believe my 503dcdi can't be the only one to run over 650 hrs.Do a de-carbon if you want to but I'd never overhaul a good running 503 at 300hrs.

Gary A/Gang:



I'm with Gary on this one.  The Rotax TBO for ultralight and experimental

aircraft engines is "recommended" only.  Not required.  It doesn't mean you

must go with a new crank, pistons, rings, etc.  What it means is to look and

verify if a component is out of spec and needs replacing.



If it was my engine, I'd run it, like I have all my two strokes and four

strokes, run them until they start to tell me they are getting tired or give

me some other indication they don't feel well. 



Establishing a base line compression test when the engine is new might be a

good idea to tell you if it is getting tired later on in life.

John im with you on this and most everything else aircrasft wise . I flew myRotax 503,  492 hrs just checked the rings every year and used the right amount of oil and before it was sold i sent it to be rebuilt the report from "LOCKHEAD' was the engine was in very good condition .I never decarboned the engine as I believed I would do more damage taking it apart and putting it back together ! and i am an LA tech trained motorcycle mechanic Im not saying that the average used and somtimes abused rotax 503 shouldnt be taken care of by the numbers but those numbers are "recomended " not etched in chromemoly .

Phil , Did you happen to ask what the weight of the fan cooling system would be?I am Only concerned Bryan at Kolb was worried about cooling .  Why not take off the pullstart and add the fan cooling I think that would be a even trade. I am going to Email the factory and ask the questiion tonight. I will let you know as soon as I get an answer Chris

 Ok guys and gals  ya'all got me thinking.... I know next to nothing about the MZ engines and have been seriously considering a re-power of my DCDI-503 powered FSII simply because the engine has very near 300 hours TT.  NOW,  when I posted that I was considering a Hirth some of you got all abrasive [Rolling Eyes]   Is, in your opinion, the MZ a better/same/worse choice than the Hirth?  Or do you die hard Rotax folks think I am simply better off having the 503 rebuilt and sticking with what I have???    I am not trying to rock the boat again just wondering how the MZ compares to the Hirth and the Rotax?

I have stories I could tell, but they are from several years back; so I  won't 

  

 I did hear that Zanzotera founders were PO'd Hirth people and that it is  essentially the same engine.

  

 I would rather have a 300 hr, 503 than a new MZ.

It is suggested that the 202 needs the fan, but not the 201. Time will tell. Let us know what the reply to your inquiry is.

      Phil , Did you happen to ask what the weight of the fan cooling system would be?I am Only concerned Bryan at Kolb was worried about cooling .  Why not take off the pullstart and add the fan cooling I think that would be a even trade. I am going to Email the factory and ask the questiion tonight. I will let you know as soon as I get an answer Chris

      I decided on the mz201 for my Firefly. I only know what I've studied online about Simonini, Hirth, Rotax (used to own a 503 on my past Twinstar), and the mz line. I will know a lot more once I get my Firefly built and start running my mz201 on it (in the Spring).

 

My mz201 weighs in at 75lbs total fly-weight without the mounting plates and h/w for the engine and exhaust system, but including everything else; belt reduc, air filter, carb, muffler, elec and pull starters, all ignition components (harness, dual CDI, dual plugs). I thought it would weigh a few pounds less, but as far as I can tell, this is still 15-19 lbs less than the 447, with 4-5 HP more.

Phill ,Got an email from Leon at the MZ factory . He says that in order to have the fan cooling that thepullstart has to be removed and the weight gain would be 1 to 2 lbs, he is going to give me a final weight for the engine with dual cdi and belt reduction and the Price later today I think .

     1 to 2 lbs for the safe.cooling of a $5000 engine is a minor weight 

 Im sorry to ask but I have lost track of who has gain in my opinion 

  ,Is  it your engine they have in the Kolb shop It would be interesting to see what Bryan says. Chris

1 to 2 extra lbs sounds about right. Let us know what you find out about the total weight and price.
