Carb Help!!!

Thanks for all the feed back guys I really appreciate. I guess im going to take her apart over the weekend and see if I can get it to work. If I decide to put the 800 back on what suggestions do you have to make it not run so rich? Timing? I dont mind using the 800 but my wife and kids dont like riding in the car because the gas fumes are so bad. It literally burns your eyes! Also with the timing, I timed it at idle with a timing light and the mark bounces between 9-10 BTDC. Is this correct or incorrect way to time it? I have a stock timing chain cover on it so the timing marks only go to 10 I believe. These are two areas I am totally lost on. Thanks again and hope I am not asking totally ridiculous questions here!


The 800 does NOT necessarily have to be richer than the 600 at part throttle. If the carb is tuned properly, you would see zero difference between the two just cruising around town.
You tune the low speed fuel mixture by changing the drop rods (metering rods) and the springs that are under the vacuum cylinders. The rods are tapered with a step. The larger part of the taper is your idle/low speed, and pointy end is your load/high speed. The lighter the spring, the less fuel your engine will see at smaller throttle openings.
This is the Carter/Edelbrock version of the Power Valve as used on Holleys.
