i got a go tech .21 5 port turbo engine. its been broke in properly by the book. my 1st race with it was today, my only problem with the engine is at topend on the end of the staraight the engine would die while on throttle. we tried leaning and richening the high side with no success. could i be fighting the wrong end of adjustments? should i be trying to adjust the low side? never been faced with this problem. i am running a o.s. p3 plug.
