RE: walbro wt 813 carby on 5b ss
largescalerc,ddm , and most other places that sell performance engines should have them. they dont cost an arm and a leg either. i had taken mine off because i couldnt get it to run, but after listening to the info these guys had i was able to get it up and going easily! i put another tank thru it and i am hooked the throttle response is much better and it has a smoother powerband. its easier to start than what i had thought it would be too.
