Hello Dan,

My 36 Handitwin has the same symptom with fuel running down the exhaust tube. Mine is also good for about 15-20 seconds before stopping and runs better after closing the petcock a running the fuel out. I had very similar  scenario on A-45. Remedy on the A-45 was to set the needle valve to 3/4 turns out from soft stop.

In both instances the objective is to throttle back the fuel supply.

Point of interest:

On the Handitwins the “1/4 set point ” would need to be set with the lean/rich adjustment lever positioned to the far left. If the 1/4 set point is set with the lever to the far right the needle valve would reach the soft dead stop about mid position on lever travel to the left.

I guess a better way to put this is to back the needle valve off 1/4 turn from soft dead stop and then oriented the lever to the far left travel position, slide over stem and lighten.

Am I on the same page?
