Ok, I got Mater running, he is my 63 F-250 4x, with 292 and 4 speed, the old 2bbl carb was caked so bad, I used a 2 - 4bbl adapter plate and put on a holly 390 cfm 4bbl, now it wants to idle fast and then slowly slow down, is this indicitive (sp) of a vacuum leak? New gaskets on every surface, carb was used and was fine 2 -3 weeks ago, manifold leak maybe,,,
Hi a curl one 1st check the carb is tight, (2) check all vacum hose for cracks , are there any plugs missing of carb ? (3) check manifold bolts (4) check point gap & timing (5) run motor and spray sum wd on your manifold where it meets the heads if you hear that the motor run better when you spray
get back to me (6) spray base of carb to , if it runs better is a gasket
Only one vacuum hose, for vac advance, everything is is plugged....I think, will check it out, forgot about the wd check, havent had any trouble with my other ones for so long.
