Replaced the carb to block gasket, no change.
The motor runs pretty well at high speed, but basically doesn’t want to run with the magneto set below the start setting. Anything below that and it dies out.
Runs fine at high speed, tuned the high speed needle to about 1/2 turn to peak up the revs. Seems like a low speed issue only. One interesting thing I noticed was that I could start it with the high speed needle closed, then start backing out the low speed needle and the revs were coming up pretty high, well into a region that should have required the high speed portion of the carb. It also starts easier if I set the magneto to full speed rather than start. I’m wondering if the low speed venturi is damaged from somebody screwing in the needle too far as mentioned in the manual above. Don’t know what else it could be at this point unless there could be something with the ignition. Still some hesitation in the throttle sometimes, I’m sure it’s related to my low speed issue.
I winterized it after playing with it today, I need a break from it, I need to source a few small parts for it to complete it, but otherwise I’m going to move onto something else until spring.
