Hello,

I've have a Fox .35 CL engine that has been lying around since I was 14 years old. When I was a kid I was never able to start it and it has been gather dust and crud for the past 25+ years. Today I cleaned it up and it looks to be in pretty good shape -- all things considered. It has a lot of compression and feels smooth when you turn it over.

My questions are how do you break in an old engine like this? Also, it doesn't have a muffler -- do I need one to bench run it (I have hearing protectors )?

TIA for your help.

Cheers!

Galen
