Plugs are good, Compression 85lb all cylinders, Getting spark at plugs, Been thru the carbs twice. Still believe it is fuel related. If I switch the primer lever to open engine runs much better, move back to normal runs poor again. Pulling plug wires while running indicates 2 cylinders are missing, but have been told that is not a good test when on muffs. Engine doesn't generate enough voltage to get a definite good spark. Needs a higher rev to be a sure test.
Pulled the plastic reed valve holder from the primer body and found the o"ring around the tube on the intake side dried up and hard. Replaced the O"ring and gasket. Seems to be much better running on the muffs, but I cannot detect change in rpms while adjusting carbs. Leaving them backed out 1-1/4 turns. Butterfly's appear to be in synch (visually). Going to put in the water tomorrow and see how it preforms.


Would like to hear anyones thoughts or ideas concerning this engine
Thx, Brian
