Hi everyone this is my first attempt to convert a homie.
Any tips or suggestions please

I don't want to sound like a jerk year but I saw your post on the flywheel and I think your getting a little obsessed/perhaps misled about weight reduction.
Shaving those fins is just a bad idea.
If you ran that engine with the fins shaved and the flywheel you developed, it would be a toss up as to whether it burned up or exploded first.

Get another engine and start again or at least get another flywheel and run that one till it melts down.
There are plenty of experienced engine mod guys that have posted a lot of information on modding the small converts, and believe me if any of the things your doing here were worthwhile they would have been done and shown long ago.

No offence.

Thanks for the advise. I just want to try it for myself, I have 5 homelite 25cc motors I'm moding. Jits all exprements. ofcourse saftey first.
Thanks

YOU CAN SAVE SOME WEIGHT FROM ANOTHER PART OF ENGINE BUT FINS MMMMM... THIS ENGINE WILL RUN VERY HOT

Most of the heat is in the cylinder. I have a Homelite 30 with a custom crankcase. There are no fins and its polished like a mirror. It doesn't get hot.

Rembember the crankcase is cooled from the inside by the fuel going through it. Altough I agree with most of the posters, start with a stocker first then add the mods one at a time. That way you know what works or not. Just to give you a bench mark, a much modied Homie 25, 16x8 APC, 9100rpm, on a muffler not tuned exhaust.

If you run the engine on glow fuel...you can shave some of the cooling fins down. You might leave the fins on the back of the cyl as is...thats where the heat is. No fins needed on crankcase. If you run glow fuel..use plug adapter...and remove all ignition parts. You can even remove the flywheel and just use a prop hub. Then use a heavy ..non wood prop for flywheel effect. Good Luck Capt,n[&:] PS You can get rid of that part of the casting on front of engine that serves no purpose.
