7 Cylinders
On the way to work this morning I got on the freeway and got my Blazer up to 65 an all of the sudden it starts acting like its only running on 7 cyl. No power. Eased up on the gas and the problem seemed to go away. Its probably not the fuel pump as I just replaced it. I thinking probably it the mechanical advance on my HEI distributor. Broken or weak springs. I have one of those recurve kits that I thought I might try. Which spring should I use. It is a stock 307. Ad what shoud the advance be at that speed. Any help ?
