Default quick engine help?

I have 2 B5's wonderful engines and produce amazing power while staying around 210-220... I have been having some tuning issues, i don't believe there are any air leaks, i had them running good after expericncing tuning issues the day before they didn't need touched or turned and ran perfect the whole next day. The truggy engine was a lil lean the following week i richened the top end up and got it running great, the buggy however was a lil more tempromental,

I guess my question is this....I can start it up and it will idle fine, but when i squeeze the trigger it flames out....there is no growining sound like its being flooded from the low end, i know its lean but i have richened them both a bit....is this a low end lean problem or a top end ...im going to yard tune the engines tomorrow to make sure they are still close, but the buggy needs put back in line moreso than the buggy, any info would be great

Once again it dies when the throttle is squeezed quickly....the tune is so different between the 2 motors with the same pipe even....i guess thats where the confusion sets in

sounds like a low end tuning issue, open up the bottom a touch, also let run and warm up, i think you will see it runs great once you let warm up a minute or two.

leave the ignitor on feather the throttle to build a few rpms to warm it up then after you get it to rev a bit take the ignitor off

+1 on the needle setting let us know what they are. Also what does it do when you slowly pull the throttle? This info will help us.

To me it sounds like your too rich somewhere. Or too small of an idle gap. Maybe try a new plug.
