I think (actually HOPE) that I have blown the head gasket on my 1054. It has been tough to start the last few times I used it, but ran good once started. The last time I used it it was still tough to get going, but ran well for a bit, then started to run rough, almost like it was running out of gas. I got around to working on it last weekend, removed the carb and cleaned it up. I put it back together and tried to get it going today. It is trying to fire and there is smoke coming out of the exhaust. Then I noticed that the smoke is actually coming out of the shroud behind the exhaust. I stuck my hand in there and cranked it over and sure enough, I can feel the air being pushed out back there.
Does this sound like a blown head gasket or do I have bigger issues? I have not had time to dig further into it yet, Are the head gaskets readily available and if so about how much are they?
