Need carb and/or timing help
Checked the flow from the fuel pump while it was off...seemed strong enough....
You need a gauge.
Stumble off idle- are the throttle plates showing more than .040 of transfer slot at bottom? you may be not using the idle circuit.
Pull it and turn it upside down and check. If your curb stop idle shows more than .040; you need to drill holes in the front primary plates. Start at 1/16"
Hey green....I installed a fuel pressure gauge inline.....I am showing 6.5-7 psi at idle, and it gets a little erratic when the idle drops real low.....
edelebrock says the pressure needs to be no more than 6 I think, 5.5 ideally. So either the gauge is wrong or my pressure is too high.....I may pick up a regulator at pep boys and try that. But if it were the pressure being too high, wouldnt it want to flood out?
As it stands, it will idle in park at 800 rpms....if I rev the engine or touch the throttle, it jumps to 1200 or so.....and wont come back down....
In drive, it drops to 500 rpms....too low.....and wants to sputter bad off the line.....even a small pop thru the carb if I am not careful...if I baby the throttle and get to around 1200 rpms or so I can pull out and acclerate OK...still feels boggy but pretty strong.
Maybe this cam is just too big.
I havent measured the transfer slot at you suggest yet.....Can I pull the carb, check it and replace without a new base gasket? I am waiting for one to ship to me...its on backorder from edelbrock.
What does drilling the plates do.....let more air in, right?
Where should I set the throttle screw when I measure the exposure of the transfer slot?
And if I do drill the plates and it truns out that it doesnt help, what is the fix to go back? Would I need to replace the plates or could I safely JB Weld? Wouldnt want something breaking off and going into the motor.....
