Choke adjustment?

[Bonnewagon]

OK, so, no adjustment on 85' 442. But that shouldn't matter since his flap closes fine. Electric or hot air won't make a difference either. Re-reading this, I'm wondering if it's a choke problem at all. What exactly are the conditions when it won't start? Has it been sitting a long time, several days? If it doesn't start right away, will pumping the gas eventually get it going? Does it start, then die? When it starts does it run fast, then drop down when it gets hot? If you run the car every day, does it start OK?

The car on any morning start after not being turned on for a day or even two
Does it, I would give it 1 pump of the gas, nothing 2 nothing, 3 nothing, after a few pump if it does turn on it's idled very very low and stalls out, then once I do get it going it smokes a bit out the exaust, when the car is on it idles high but takes a Little long for it to idle down to normal, after the car is running it's just fine, I can turn it off and back on lime nothing.

First off, it sounds just like my car after a few days. Empty fuel bowl because of the alcohol in the gas makes it evaporate fast. If I start it every day, no problem. What I do is crank it a bit, pump pedal once only, and if no start, crank a bit more and pump pedal once only. By then it starts normally because now the bowl is full of fuel. As for the fast idle being too low, go back and look at Tobyp's picture of the fast idle screw. You adjust the fast idle with that, in the morning when it's cold. Re-read his advice, it's right on. As soon as the motor starts, the choke pull-off opens the flap to a specified measurement so the motor gets enough air to run, usually between 1/8" and 1/4". If the motor stalls, it needs less air. If it smokes and chugs, it needs more air. Then as the motor warms up the flap opens slowly all the way and by then the green tang behind the choke housing drops down, releasing the fast idle. That's when you tap the pedal and it drops down to curb idle, which is adjustable by a screw on the driver side of the carb.

I've tried it that way Saturday morning and it wouldnt turn on,
Takes way more than two pumps to get it going, the way I usually get it on is by leaving my foot on the Gas and turning it.

It wasn't always like this, the problem started about 8months ago.

Have you checked the accelerator pump discharge? With motor stopped, pull off the air cleaner and open the choke butterfly. Work the throttle by hand and observe the pump discharge ports located in the primary bores. There should be a long solid squirt of fuel each time the throttle is opened. If not, there's the problem.

ok, so open the butterfly, work the throttle and i should see some gas squirting?
if it doesnt then the accelerator pump is no good?
but if it wasnt squirting wouldnt it not even turn on?

Eventually the motor would start just from cranking, because fuel would be drawn in by the choke flap being closed. The pump shot gives it a big head start so it fires up fast. This pump also gives you a shot of gas when you hit the gas pedal hard. Just driving easy, you wouldn't notice it being weak. The test is to floor it, and if it bogs or backfires, you have a weak pump shot.

this sucks, i just tried turning it on and wnt thru the same usual thing trying to get it going, i tried flooring it after i warmed it up and got no backfire.

Maybe your well plugs have developed a leak and all your fuel is leaking out overnight. This happens alot with Qjets. The fix is to use epoxy to seal them shut. Todays gas isn't very carb friendy either, but I doubt that's your problem.

I think you should just buy my perfectly running rebuilt 85 442 carb and all of your carb problems will go away. :wink:
