Hi Europaphiles,



So it's been a few weeks but I have finished up my panel upgrade to a 

Dynon EFIS and it all works great - well it comes on at least and my 

avionics shop passed the transponder operation.



I went to do my first flight with it this evening and just could not get 

the darn engine (Rotax 912UL) to start. Just lots of cranking from the 

freshly charged battery.



Obviously I had removed and replaced the panel but everything seems to 

work OK, fuel pump, starter, etc. so I don't think there is anything 

wrong there - although I would like to make sure the mags are on. The 

best way I can think of is to test for a spark. Any recommendations out 

there for testing to see if you have a spark? I believe the removal of a 

spark plug is not recommended on a Rotax. I felt the hint of a kick once 

or twice so I suspect they are good.



My suspicions lie with the carbs - in particular the choke. It is really 

stiff and the geometry is such that it never quite fully opens. I 

removed the air box and stuck my nose next to the air intakes. 

Considering the amount of cranking and choking I had done you would 

think I would be able to smell fuel - but couldn't smell anything. 

Anyone used some kind of 'quick start fluid' like the kind I use on my 

stubborn lawnmower or is that a bit too extreme?



Anything 'more obvious' I can try?



Regards,



Martin Tuck

Hi Martin,



here comes my story:



Damn thing wouldn't start, not even with lots of swearing. Removed one spark plug and I could smell fuel. Warmed the ignition boxes with a hairdryer for 3 minutes and the engine would start right away. 



I had this problem two times. So if ignition is the problem, there you have (most likely) the culprit. 



BTW: ignition boxes for my Rotax (914) are 880 EUR each.



Good luck!

Hi



This company in the Netherlands was discussed on the forum a while 

back.  Rebuilding ignition units is one of their services.

Thanks Roland,



It seems to be a choke thing as I sprayed some Quick Start fluid into the air box and it started right up. Oddly enough though, the Alt warning lamp is on all the time. The only thing I have done electrically was to add a diode on to the main solenoid to protect the avionics from spikes when shutting down. I’ve never seen it lit in all the years I have had it.
