I use the choke to start it - It has been starting really hard on cold starts with current jet / setup, great when warm. Not sure on the heat rise flap. Planning on checking that along with timing and vacuum this weekend. The accelerator pump did squirt out some but no idea if enough.
Carb jets -
Original was unmarked.. looks bigger than .5 - similar to .57
.57 was in it for a little bit - started good but didn't run great
.50 is in it now - starts real hard when cold - runs great when warm at low speeds, cruises good, and accelerates Ok
Going to do full rebuild on one of the carbs and then switch. Suggestions on jet size?
