Problem getting a 1979 GMC 350 running
It has always ran great. I did adjust all of the carb per spec. it was outside. I took the passenger side valve cover off and two of the rockers are loose (nuts are not loose) and one isnt on the valve. How would that happen- stewy4344

After. Im borrowing a light to take a look. Haven’t looked for the timing marks yet. Hope they are at 2 o’clock. Don’t know how it would get out of time though- stewy4344

Problem getting a 1979 GMC 350 running
It has always ran great with no issues. I was stored outdoors. When i did the carb, i went through and did all the adjustments. I even tried a different carb. Same behavior. I'll do a compression check on all the cylinders and see if anything jumps out.- stewy4344

Problem getting a 1979 GMC 350 running
I disconnected the exhaust and it did start and run rough with no pick up when applying throttle (although can hear the four barrel kick in). It sounds like number 6 valve was making a clacking sound. Bad valve or cam?- stewy4344

I can feel exhaust when it is running, but good question on whether maybe the converters aren't fully working. I will try that. I can't think of anything else unless it is a vacuum leak and I haven't been able to find one. Thank you- stewy4344

I did blow through the lines and put on a new filter. Bowls seem to be full of gas and in fact it spits a little gas out of the top when it is turning over. Color originally was silver and black. Now red, but am going to take it back to silver- stewy4344

Have a 1979 GMC 1500 with a 350. It sat for 18 months and when I took it out, there wasn’t much power and full throttle didn’t have much pick up. Changed out a rusty tank, went through the carb and now it starts barely with full throttle, runs for a few seconds and dies. Carb is full of fuel...- stewy4344
