Hey Everyone,

I just purchased a secondhand OS BGX engine, but there is a lot of gunk around the cylinder head.

1...What is the best way to get baked on fuel off the engine without damaging its appearance??

2...AS I dont know the history of the engine, I noticed a lot of blackening in the interior of the engine, it runs well, but how can I check that everything is alright?

3...Do I need to clean the interiour or the carb?

Thanks for your help!!!
