Fleetwin, I ran the motor in the test barrel today at the Start
position, in neutral, for about five minutes the first time.
It seemed to be having fuel issues, but if I squeezed the primer
bulb it would straighten out for a while.

I raised the fuel tank up higher and it didn’t seem to help much.
Opened up the gas cap in case the vent was plugged, assuming it has one,
and that didn’t do much either.

When it died, I felt each plug, and both felt “barely warm”.
Pulled the plugs out, and both looked wet and kind of fouled looking.
I cleaned the plugs up a little, and switched them around, and it ran
about the same.

Then put it in gear, and opened it up, and it sounded like it was only
winding up half way. Tried choking it partially to see if it would “pick up”,
and ended up killing it.

Decided it was time to inspect things further.
Not sure how much the owner messed with the low speed needle.
What’s the initial needle setting on these motors?

Thanks!

Prepare to be boarded!
