Alright, i have a 1985 chevy silverado 4x4 it came with a 305 and the 700r4 tranny, i swapped the motor with a higher performance 350, i have the dart lightning heads with i believe a 9:1 compression ratio, a .450 lift .460 on duration cam, the crank was milled at the usual rebuild measure, a hundred thousands i think, and the block was bored .30 over, i have the stock quadrajet carb but it was rebuilt and i was told by the guy who did it that he tried to make it a little more hot rod to fit my motors specs, and his name is a pretty good one in my town for carb rebuilds, so i figure its rebuilt right, but when it came to getting my motor to run we had to put a new spring kit on my distributor and the carb was funny on adjustment, and the timing was a pain, but after was all said and done it ran pretty good, but now it has this thing it likes to do where it will run really smooth but randomly it will act like its bogging down when you hit the gas and the truck will shake more than usual when accelerating...what can i do to make this go away? i was told it could be a peice of trash in my carb, but im not too sure on that, i was also told my float could need readjustment but i just dont know.......id like some instruction on some things i could try and do....i know my way around a motor compartment ok so anything would help thanks.......Red

I don't know much about carbs, but I had this problem a few years back in my S-10. It was occasionally very bogged down and sluggish off the start. It turned out just to be that my fuel filter was shot. Just something worth checking out since it would be a cheap and easy fix.
