I just finished a conversion on a stihl 25.4cc wacker motor. All I can say is wow! Started right up in the cold weather. The first tach reading was 8k on a MAS 16x8. Then I noticed the choke was still part way closed. Opened that up, richened the top end a touch and was getting 9k on the nose with the MAS 16x8. The throttle response was amazing, lightening fast with a reliable stable idle of 1200. I love these einges. The only other prop I had lying around at the moment was a 20x10 mas. I threw it on for fun and got 5k with sluggish response. Interesting but not really useful. The only mods done to the engine were to clean up any carbon deposits(used engine) and I removed the bass gasket and sealed the crankcase with RTV to slightly increase compression. If you can find these engines convert them! Mine came from a stihl weedwacker.

Congrats on the achievement of satisfation. I'm sure there will be many more with conversions.

Enjoy,

Jim

W8ye: I have a older model 011AV Stihl chainsaw. What CC would that be? Also a Echo 320 saw. CC? Thanks Capt,n

captinjohn,

My records show the 011AV being a 41cc engine.
Sorry but no info on the echo.

if im right the echo should be a 32cc.

Buck...That Echo is a mean little saw. I bet it would make a good conversion! Thanks Capt,n

Put a MAS 18x6 on there. Mine turns it at 8k rpm. It turns a Zinger Pro 18x8 at 7k rpm. I have mine on a 80" Robinhood. Flies it great. I use it for aerotow and dropping skydivers. I am about to put an internal drop box in it with bomb-bay doors.

The mas 18x6 is on order!

do you have any pics of your conversion?
