hey guys, this is a question about a carburated small block chevy, but i figure ill ask here because its most likely going to be a generic answer to my question...my dad and i just rebuilt a 350 sbc to put in his chevelle...its like the 5th time hes built a motor, so all the tolerences are spot on, the valvetrain is quadruple checked clearence wise (rockers and whatnot), we have the fuel pressure set correctly and we are definately getting fuel to the carb because we flooded it twice and had 3 small carb fires....we even tried a different carb we had from the previous motor which we knew worked, and it didnt make a difference...
we primed the oil pump to 40 psi for about 2 mintues, we set TDC 3 times, then advanced the balancer to 4 degrees below TDC...we set the dizzy perfectly to the Number 1 plug, all the wires are on correctly, firing order has been triple checked, the plugs are all good, all the wires are getting spark, and everything seems like it should fire right up...
IT WON'T!! and we can figure out what the hell is wrong! the starter turns the motor fine, but it doesnt even so much as sputter at all like its going to start! we thought maybe the battery was a bit undercharged so we hooked jumper cables up to my dads durango, and fired it, and still nothing...at this point, we spent 7 hrs trying to figure out the problem, and we havent been able to....at this point my dad is getting very frustrated, and i really wanna help him out...i spent all day out there today with him just like i always do, and as much as i LOVE to work on the cars, its just very discouraging...
as i said, this is probably a generic answer, so if you have ANY advice, please post up...thanks a million:SNSign:
