i am having issues with my car other than the steering problems i have yet to fix ( not driving my car ) i have chaged almsot the entire fuel system other than the tank and i have changed the distributor wires plugs etc.etc. carb, intake and exaust but still it have issues with throttle response when ever i hit the gas at all it seems to hessitate and almsot stall i have the carb completley leaned out as ive tried it to richen it up and it does nothing other than make it worse if any one has any tips or any ideas as to what it may be help as i am out of ideas and just want it fixed of and its a 73 mercury comet 302, automatic, 2 door if that helps at all
Hi, We will need some info from you: 1. what kind of Carb, intake? 2. dizzy, point or electronic, type of wires, coil? 3. Fuel pump mech, or electric? 4. Where is the timing set? 5. What is the Vacuum reading? 6. did you set the airscrews with a vacuum gauge? If you use a vacuum gauge to set airscrews it will not be lean or rich. It will be set to your engine needs. 7. have you pulled your plugs to check the color? 8. check all intake bolts, carb mounting bolts. 9. Check all vacuum hoses for cracks and are connected. 10. save this one for last. The fuel sock on the fuel pick-up in the tank is clog. let hope not. 11. Can you hook a fuel gauge up right after your fuel filter and before your carb inlet?
Remove the tank, drain the water and alcohol out of the bottom of it and remove the sock filter. Then flush all the lines and put a new filter on it. My bet is that will fix your problems. (other than the steering problems)
1. carb and intake are edlebrock performers serires carb is 600 cfm 2. umm what( really i dont know electronics ,bosh premium wires, and coil stock replacement) 3.feul pump is mech (just put new one on) 4. haven't check timing latly but when i got the car i did and it was fine ( maybe should check again though) 5.-6. no vacuum gauge 7.plugs are fine 8.all bolts are good checked then double check everything 9.all lines are new 10.i don't know bout hte tank its olld and looks like itll need replaceing (geting rusty) thanks for all the help so far ill check back after i try those last few things then'
Bet it's either the carb's accellerator pump circuit not adjusted properly and/or the timing's retarded.
The Edelbrock 600 CFM carb doesn't have and accelerator pump - it uses metering rods and jets. There is a problem with a lean condition when the engine demands fuel.... since everything but the tank is new or checked then that leaves the tank and those components in the tank.
1. All caerbs have a accelerator pump. 2. get a gallon gas can. 3. disconnect you "in side" of the fuel pump hose. 4. put the "in side" of your fuel pump hose in a gas can 5. start the car and let it warm up. 6. when warm ,rev it. 7. let us know. 8. do you have a point dizzy?
Then why does Summit list these two accellerator pump assemblys for Edelbrock carbs ? P/N 1467 & 1470
OK, I am a Holley man whose only experience on the Edelbrock is when it was the AFB - long ago. I will look at some specs and get back to you.....
OK, I'm back and blushing. Yes it does have an accelerator pump - (it doesn't have a power valve- that is what I was remembering and I transferred it to the accelerator pump) So, I am going to slink away back to the corner and stay there until I am asked to come out.
