is the idle on the remote set to 0???? and lower ur idle a little so it idles lower...and raise ur low speed needle a little so when u hit the brake it doesnt stall out

sounds like your LS is too rich. If you floor it and it cuts off, its getting too much gas. Lean it out about 2.5 turns and see how it runs then.

I just went thru the same problem pretty much. set the highspeed 3 turns out or tad more . lowspeed 3-1/4 out. thats running it rich but these engines like it rich. check your controller settings for the throttle like "muggy" said . it should run then start leaning it out from there..look inside the crarb. and make sure the slide has a small gap when you hit the brake also. like 1/4.....>II<.....about that much lol....low speed is the one on the slide idle is on back of carb
