305 V6 Engine question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Alaska_Ryan · 03-15-2010, 03:28 AM

Driving home with my 69 GMC which has a 305 V6 (yes, it is a 305 V6). The truck starts to shake, shudder and backfire horribly. I felt as though I was on an unbroken horse. I got it home and parked, but now I can't get it started again.

The engine turns over fine, but it will not catch. I have spark and gas going into the carb. I even sprayed starter fluid into the carb and nothing.

The only thing I can think is the timing chain jumped some teeth. Anyone else have any ideas or suggestions?
