Yes I make sure the bowl is full.Appears choke is closed and this motor when the choke is pulled it gives more throttle also.This motor has no tiller it is set up with a knob and it uses controls,but I am running in barrel..The knob is hard to keep in position due to the constant pulling on the rope so that causes an issue.If the controls were on that would help hold throttle in place,but with the choke giving it that extra throttle anyway the knob issue only matters after starting warm.Would advancing or retarding the points opening make a difference if fuel delivery is ok?
