Earl So good to see you back,and spending. I have a AM 25 (2-5 cc) Diesel that I may fit to one of the butterflys just for fun.I need to get a timer to limit the engine run as there is no throttle. One butterfly is in the shop being re covered, I did have some other ideas but as other projects are now got my intrest Butterfly rebuilds are on hold. Things have not changed at least 10+ on the build not to mention the re builds. Hope all is well Yours Paul T
