Briggs stopped posting cylinder compression years ago so there is no answer to your question. I asked for ALL engine numbers because the techs on this site (those with 20+ year of experience) use these numbers to to tell us more about the engine than 90% of the people who need help do. When questions are asked about compression you rely on past experience most time, not a spec. Being that we may be 1000 miles away you need to supply us with the info we request if you really want help. As I stated a variety of causes can contribute to a compression problem, but you gave us so little info that we had to fall back on guessing as to the cause. Another thing is that a major blown head gasket will not allow an engine to run properly after it is started, that’s why I suggested looking at a fuel problem. It’s time you back off and pull up your britches and start looking at your posts from our side of the fence. You are mad at us because we asked for more info which you didn’t give us. I guess you think it is our problem for not responding to your request in a manner that you feel you are owned. Sorry about that, but it doesn’t work that way. Time for us to get back the members who appreciate any help they get, as they pay us back with a thank you, even if the problem is solved by the time we get back to them.
