What is your cranking cylinder pressure? What spark plug are you using?
ok, the spark plug is an NGK XR4. I didnt think that was the actual number but looking it up, it actually is, just XR4..also lists as 5858. I cant find a chart that shows what the next colder NGK plugs are.. Also, what other things will happen with going with a colder plug? it wont run too rich will it?
