just picked up a MS440 saw, 70.7cc/ 4.3 cu.in
Was hoping to use in a nolsen 1/4 P-51 or my almost complete "Weeks Special"
Pro`s , con`s??

Here is my Stihl 046 conversion. 76.5cc (4.67cu.in ?) I did not convert it. RCIGNs converted it several years ago. It's never been run since the conversion. Not to my knowledge anyway. I bought it here on RCU from another member about 9 months ago. I think RCIGN probably ran it to dial in the ignition timing, but that's all the run time on it. Brand new cylinder, piston, pin, ring, seals etc. I'm pretty sure the case, crank, rod is original.

I haven't started it yet. I have no idea how it's going to run. I am praying that it will spin a 24-10 around 7000RPM. The plane has been a long time getting to completion. I will be lucky to have it finished for next spring.

YESSSS! Finaly see a shop as messy as mine.

Messy? [>:]

That was just after I cleaned it. [X(]

I moved this to Engine Conversions.

I just have to be selective on the pictures I take or I have to crop out the mess. Nice engine. I would bet that Ralph did a little tuning run before he sent it back. Good luck.
