Double pumper rebuild. Ran great, now fire, secondary squirting.
Hi, Repost from Holley forum but have no answers. Thanks!
Hi, I have a Pontiac '65 LeMans/GTO clone 428 with Holley double pumper 700 cfm IIRC. I rebuilt the carb this summer, ran perfect. As it got colder, to put the car away for winter, I started it again. The carb backfired & fired twice at the carb. No air cleaner on at that point. I noticed that when not running, the secondary is squirting alot when I move the throttle. Is this normal? I thought only when the power valve opens or something, maybe I'm wrong. It is colder now than summer, maybe it doesn't like colder weather or a maladjusted choke? I think I have the mixture leaned in a bit, and I hear that may be bad. I'm just wondering if I blew out a power valve or something. I just winged the timing, but it ran perfect & responsive (in the driveway) over the summer. I could turn the key with no gas and have it start & idle, now I'm afraid as it catches on fire. Thanks for any suggestions. I have resurrected the engine after sitting for about 10 years, I had previous comp cams 268H install, new fluids, points, etc. I am just a bit afraid of fire, wondering why all of a sudden it wants to catch fire when I let up on the throttle to idle. Thanks! Steve
