I came across a "dead" chainsaw this weekend. I got it for $20. It's a McCulloch 35cc.

Has anyone done a conversion on this motor? Carr Precision has a conversion for a 32cc, but nothing listed for the 35cc. C-H ign. has some conversions for smaller McCullochs, but nothing for this 35cc engine.

Anyone have a converted 35cc engine? Where can I find parts for the conversion? How do they run?

Thanks

I can make what ever parts you need to convert it all i need are the technicles or you can ship it to me and ican ship it back ready to fly thanks Kenneth

Thanks for your offer Ken.

I would be interested in sending the engine to you and having you convert the engine. I will definetly want to get rid of the magneto and use an electronic ignition. A new muffler for inverted operation would be great. I'll need some way to mount the engine. The engine is a rear exhaust with side carb. So, engine mounts will need to allow for the rear muffler and crankshaft where it sticks out the back.

Email me, and we'll talk more. And thanks again.

Before you get to wound up, check and see what the crank bearings are. If they are ball bearings go fo it. If they are rollers or needles back it in. Only the ball bearings will take side thrust.

The crank bearings are needle. Can I replace them with ball bearings?

Any thing is possible, if you want to spent a couple of hundred$$ on a $20 engine.
Basicaly this is a learning experance.
You might be able to maching a bronze thrust washer to go between the crank and crankcase. This would take the load when the crank moves with the prop. Some of the old Q35 used this method.
