Hi, and thanks for taking the time to read my post. To begin I would like to explain how the engine acted when first purchased. I was able to pull fuel into the carburetor by putting a finger over the muffler and turning the crankshaft counter clock wise.

I have since changed the backplate , which didn't come with a gasket when I received it , and also I replaced the cylinder head which had the thin metal gasket installed. The muffler sustained a gash in it on one crash but I have block up the opening with silicon.

Please tell if I need any new parts for this engine or tell me if this is normal wear and tear and I shouldn't worry about it not holding pressure. I also made a gasket out of silicon and paper for the backplate.

Thanks,

Dave.
