Thanks, it does have an auto choke, and I remember it working last november when I bought this thing, it would actually rev high for like 20 seconds and slow down after that, not noticed that this year but it was 80 plus out...maybe that is bad, like an autobystander on a Honda. My thoughts on the petcock is yes, when you shut down, the vac drops on the intake side, but is not supposed to behind the petcock, in a short time anyway, so only a few revolutions of the engine are required to bring the fuel to carb? So if diaphragm is bad fuel goes further back than intended? Thanks for the tip on not cranking the engine without plug, but I totally have spark. :) It is "cold" now so will test it out at lower temps when it stops raining. Thanks for the input, I appreciate it. Where would the fuel go if draining from the carb? It does not smoke or anything, and when hot pops right off, so I doubt plug is fouled. (edited)
