They well provide gallons of fun. Thanks speedy
well im going to see how, it runs with the new glow plug it did start to idle good and a bit more punch, but my battery wire came apart during the warm up lap.
so if i feel i need more, lean the top end out after the second gallon thats a big turn ! i usally turn the the main needle about 1/4 to a half of a turn.
it ran 235 when my low end , was running rich but its proberty a little hotter now but thats when it was about 90@ out and humit.
