Odball issues.....
Looking for second opinions here....
I currently am driving an '84 BII, brand new Crate 2.8L with Reman carb, all of about 5000 miles on both...
Here is the issue:
1) Idle at times is Super low (around 400RPM or less) and rough
2) When the idle sits that low, it also is gutless, all the way thru the power band, in fact, just barely hit 45MPH, foot to the floor.
3) When it is running well at idle, when floored, it's gutless. It should have some get up and go..... Not floored, runs just fine. No issues, smooth as glass, has some power as long as it;s not floored.....
Now, that being said, here is what I have gone thru on it:
Full Ignition system inspection, including timing check (spot on). Everything is all new as well. Plugs, wires, cap, rotor, filters, O2s.
Carb cleaning (reman carb, went in the same time the engine went in), though it really didn't need it. Changed the fuel filter (twice) to verify it's cleanliness. Also fuel pump output check. It fills a quart jar in no time flat. Pump is new, so that rules that out.
The Cat has been gutted, but not by me....
PLENTY of compression, brand new engine, so that shouldn't be an issue....
It sounds to me, like I have fuel issues, as in running lean. If I close the choke plate by hand with it running at normal op temp, it runs FAR better. This supports my lean fuel theory.
I have taken my propane torch out and run raw propane around the bases gaskets, spacer and all the hoses, no change in idle....
The Evaporative emission controls got eliminated when the engine got put in. Meaning, the carbon canister isn't used anymore..... I do have one open port, next to the accelerator pump. I can't seem to get a vacuum reading off of it.....
Now, that being said, what the heck am I missing!!!
Can I adjust the mixture screws to eliminate the issue? I know the two on the carb are for Idle, but would changing the jets help? If I'm gonna go that far, i'll just get the duraspark system of a mustang 2 and call it good....
