holley's will not idle below 1800
Trying to help a friend with his 427 fairlane, we pulled the (2) holley 450 mech. sec. two times, disassembled and checked carefully, reinstalled, started and while idling, sprayed starter fluid around the base of both carbs, did not speed up, sprayed in the valve cover oil filler and still nothing. Adjusted timing and still no luck. When backing off idle screw from 1800rpm, engine just dies like it's out of gas?. Feedback welcome.

It might be running out of gas... to the idle circuit.
Do you still have the old gaskets from the rebuild to compare to the new ones ?

In 68 I had a 55 Ford Custom with a 406 +.040" .single 600 Holley and a Ford C8AX-6250-D camshaft. 330° duration, .600" lift 115° overlap. It also was one of those 1800 RPM idle numbers. I had a heck of a time with keeping temps in the zone. I had a large F 100 truck radiator in the front. When it wiped a bearing at 8400 RPM and scattered the next day. I then built another 406 and went down to a 324° cam and tri-power setup. I let a frend drive the car and he wrapped it aroud a tree. DesMoines IA traffic police court had the photo a display with other horrific wrecks back in 73 or74.

FYI........It's fixed, we went from 60's to 65's. I'm confident that wasn't the only problem but what the heck, it's running great. Good lick at 1200 rpm.

Michael, these are the same 450's I bought from you, I went with the in-lines and sold them to this guy.
