| | | | Joined: Apr 2005 Posts: 25 Apprentice | | Apprentice Joined: Apr 2005 Posts: 25 | My Chevy truck has a 350 engine with a Stock GM HEI distributer with Vacume advance, RV cam, Holly carb and manifold, 350 trans. My problem is that the engine starts and runs good but goes flat and nearly stalls when I shift into drive. I have to feather the gas to accelerate to about 5 mph then the engine runs well. I have set timming to 7 Degrees advanced at Idle with vacume disconnected. when I connect the vacume the advance climes to about 35 degrees adv. Any suggestions as to the solution to my problem, ignition or carb?
Thanks in advance for any suggestions. | | | | | Joined: Mar 2005 Posts: 1,029 Member | | Member Joined: Mar 2005 Posts: 1,029 | Try more initial advance, assuming the 35 degrees is not at idle with the vacuum advance connected. You did mean at over 2000 RPM, right? | | | | | Joined: Apr 2005 Posts: 25 Apprentice | | Apprentice Joined: Apr 2005 Posts: 25 | Baldy
Thanks fore the good advice. I advanced the timmung and the truck runs great, no hesitation and also runs cooler | | |
