hey, big tip for a ya,..........run it rich. I have the 24/7 also and i dont have a temp gun. I was racing at my friends house and he does and he brought his in to temp(has a 2.5) and so i thought oh what the heck,................mine was 351!! it is the older style head so if i was you i would get a better cooling head.

luckily i wasnt running it for that long, and shut it down right away. It still has a lot of comp, and sleeve still looks good, but i probably took about 1/2 gallon off its life

im running at 4 turns out right now and i can barely keep it below 270!

I ordered a different head, hopefully it will help, I havent had any tuning problems with mine tho, i leaned the low speed just a hair, and messed with the idle untill it would idle for a good 20 sec.

sorry it doesnt really help much, but trying to let you know b4 you frie you engine. break in settings at 2 1/2 out.............im at 4???? whats up with that
