Old Man with a Hat
A few weeks ago I bought a brand spanking new Edlebrock 650cfm AVS carb to go on my 383. Did the install, everything went well on start up: no erratic idle, no vacuum leaks, no fuel leak or smell, yada yada, and WOT down interstate 295 are beautiful (ever time). Fast forward to now: WOT is still nice however I cannot get the carburetor to idle worth a damn. After a few moments at a stop lights it will idle like a cylinder is dead. When I get back on the interstate and get the mph's up this condition clears up completely. I've checked a few things before throwing this out on the board:
vacuum leaks around the carburetor/intake manifold (negative)
too rich/too lean idle mixture (good)
spark plugs (all cylinders are firing)
Fuel, timing, blah, blah....this problem has gradually crept up to the point its a real chore to keep from shutting down from the poor idle at stops.
The ONLY thing I have not checked (and this was suggested by Edlebrock) are the float levels; apparently there should be exactly 7/16" space between the floats and the top of the carb (or bottom of the top). I guess that's next, but has anyone else run into this?? Was it bad float level or is there something else I'm missing??:icon_study:
