 After a long delay to assess the real world success of the structural improvements made on the design, my 601 xlb project is reaching the point that I need to commit on an engine. I have always been planning to go with a jab 3300. 

 I would like to know owners recent impressions of the engine and specifically :

 - high cht's in the zenith 601

 - top end rework required at less than 1000 hours rather than the advertised 2000

 - improvements that may have been recently implemented

  - thoughts on the bing carb

		   - thoughts about Jabiru USA

 - any other pros or cons that I should be aware of 

 

 Thanks very much in advance,

 Bill

Bill,

         I had a 3300 in my 601XLB and finally gave up when the through     bold issue came up. The engine idea is nice but there are many     details that are problematic. There seems to be a bit of luck in     getting good CHTs. There is very little tolerance for a high CHT,     nothing like the small Lycomings which we use in production planes.     They don't even typically have a CHT monitor as it is very hard to     harm them. I had a Rotac carb and that helped a lot but there is     still a fundamental design error in the intake plenum. I know there     are many very happy users of the 3300 but you should expect to have     to give a lot of TLC.

         I now have a Viking engine. The engine itself seems to be     indestructible (it is really a Honda) and the gearbox seems to be     well behaved but I have replaced almost everything else so I would     have a hard time recommending it in stock form.

         If you are still a short time away from delivery (6 months??)     you might look into the Superior Gemini. While it is new to the     market, it is being made by a very well respected manufacturer. If     you do want to go with the 3300, I would consider the Camit version.
