Hello All, My recently rebuilt 350 Chevy has on heck of a shake whiling idleing and through out most of the throttle range. I have a Brand New Edelbrock Carb, new rebuilt distributor, Accel Plugs, Moroso Wires, AC Delco Cap and Rotor button. (All of the items are less than two weeks old) About a week ago, I noticed some hesitation from a dead stop, so I adjusted the carb. and the timing to 10 degrees btdc, and it ran fine. This past Thursday I stopped and filled it with Hess 93 Octane gas, and it wasn't long after that , it started shaking, choking, backfiring etc. So, I checked the timing with the vaccum advance off the carb. and the timing was at 8 degrees btdc. I reset it back to 10 degrees, but it still acts as if the whole engine is out of firing order or sequence. It hardly will stay running on its own. I also noticed not too long ago, while the engine was idleing, a "CLICK" sound coming from the drivers side of the engine about every 10-15 seconds and a low toned "WHINING SOUND", even warmed, it still does it. Since the very first day of firing the engine, it has sounded like a small diesel , until it warms up. I have been around Chevy's all of my life and have never seen an engine (SHAKE) like my engine does right now. Can anyone assist or advise me of what the heck is going on?
