two stroke kicker motors

[hoolee99]

Carb pulled and cleaned found it looks like a spring or clip is ,missing on top of the ( insert the right word of the piece I am explaining). The part that fits into the jet under the arm attached to the float that closes off the jet. Anyway it's missing a clip according to the diagram, However got it running was doing we'll then all of a sudden it quits. Go back out start again starts running again. When setting the points does the throttle position on the handle make a difference, Do I set points to slow on the handle or fast or middle
