Put a new tank and lines on. 12/8 prop. Cool power 15%. OS-8 Plug. the gauge for the push rodsgo and no go. I think they are .03 and .10. The no-go would slide through very easy. Adjusted to the .03 would slide in but not the no-go one. I don't have the engine here with me so I am not 100% sure what the size of the go and no go gages were. What ever was recommended for that engine. When we first started working with it, idle was the only thing it would do. I did start the hsn and lsn at 2 turns out. One post said lsn only 1 turn out. We had to turn the hsn out approx 3 turns to get it to run. Then we still had to prime it every time before we could get it to run at all.
