ran my go tech 5 port today. i sealed up the carb boot with a flexible rubber version CA glue (its the black liquid version that flash tak make, its for rubber tyres etc)
anyway the car had good power, but i did find it a little tricky to tune. it was hard to find a good low end idling tune, it would load up and react rich and required blips of the throttle to keep it clear. I did have major power though, the engine was very strong down low, top end was similar to most other buggies.
oww by the way i didn't experience the car leaning out like others reported, and the tune didn't go funny going of a jump either.
