Post by: rene knoll on March 20, 2014, 01:26:15 am
anybody know why an opposed carb seems to run when you first start it and gas on it while in neutral but then when run out on track just wont work,i gotta choke them to keep them running,and also anybody happen to have 3 that actually work,thats how many out of five that dont work

Make sure the fuel tank is vented, and also make sure the vent hole on the top of the carb is not blocked by filter adapter, or gasket.
