Any reccommendations for jetting of a 3ckt 1050dominator on a 632 street duty motor?
This 632 came with an AED carb, no carb specs.
It won't idle, cruise at low rpm/mph - like when driving thru 25mph speed limit. It 'bucks and surges'. The idle ckt restrictor was .031, air bleed about .070ish (no number), i drilled the restrictor to .041 and that improved the no-load idle but it still won't drive thru town.
Thanks, oj
Thinking what cam, rear end gear ratio combo your talking about.
whats the numbers on cam. you could very well be under the power curve of the engine and low cr with big cam will make a big engine trip on it.s feet at low rpm =air speed thats were many engine builder. just do not get. i know what works on the street with the big engines with low cr. heads that maybe to big as well. many guys go for for big numbers. you have to drive it,it is going to be at low rpm on the street.call aed carb and tell what the thing is doing? drilling the idle air bleeds helps but not much i done this . do you have the back barrels cracked if so you want to open the up back idle air bleeds as well .as its 4 corner idle i try to run idle even front to back. i used many 9377 on the street for 24 years out of the box with main jets step down and slowing down on the rear cam for back barrels
I spoke with AED and they are concerned about the carb and believe something is internally wrong. They felt that when i drilled the restrictor it should now be pig rich and since it isn't they want me to send the carb back to them so's they can have a looksee. I would like to send them the whole car - they are under 3hrs away, i am discussing this with the owner and we'll figure it out today.
Thanks guys, i'll keep you posted. oj
when you drill the air bleeds out it leans the idle air mix out .that is what you drilled out? if a new HP holley or older rework carb there made to unscrewQuote:
