Please help guys. I have a 35cc Maccullogh engine converted for RC use. I can't get it to run. It doesn't seem to pump gas. Please look at the pic of the carb and tell me which fitting I need to attach the gas the gas line to. #1 or #2 I am pulling my hair out.

Gas to #1, cap off #2. Not sure but I'm guessing #2 was for a primer. Make sure the diaphram under the cover near #1 is flexible and that the pump flappers are not curled or otherwise distorted. Also, be sure the diaphram under the cover with the 4 retaining screws is also flexible and that the metering needle also moves freely. You might need a rebuild kit if the carb has very much use on it.

Thank you Truckracer.

Yours is a Wt Series carb. Here is the maint manual for it. http://wem.walbro.com/distributors/s...s/WTseries.pdf
