Starting up after warm with carbs.., i'm confused Options

[Hammy]

My 1.7 has these carbs on it. They have an electric choke so starting it up cold for the first time is quick and good. But i'll go driving around town... Stop at some stores for 10 minutes, and when I come back to start it up, how do I do so? Depress the gas pedal like the first start up? I usually just turn the key and it'll turn over forever but not fire until I pump the gas a lot, then it'll catch and idle extremely low and pop and bitch at you, and you have to rev it for around 20 seconds before it'll idle right... This is embarassing sometimes as I have a lot of pride in my car (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) So, How are you supposed to start up after it's warm? Is there a certain way or is something screwed? Also.. there are sometimes some small pops of backfire, not huge blasts but just a small series of pops. I am wondering if this is normal?

Any help would be great. (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif)

(IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) The methodology I used with my first car, a '73 super beetle, with very similar setup is:

No matter cold, hot, or warm, one full stomp on the pedal is what it took--

But another point--make sure the electric choke covers are adjusted to the proper tension--this should have come with the installation papers--if it is at least 70 degrees outside, they should be fully open and not close at all when you blip the throttle plate open to set them--just loosen up the cover screws and turn in the direction of desired tension very carefully.

Also make sure your idle jets and main jets are sized correctly--have you taken a plug out of both sides to see the burn color??? This simple truth tells all on jetting--you want a light tan color on the insulator---a pure white insulator is too lean, go to bigger jets. A dark to black insulator is too rich, go to smaller jets.

start from new, warm the car then replace the plugs, start and let IDLE for at least 15 min--take a plug out of both sides and refer to color sequence for your idle jet sizes.

A slight color change from light tan means go to only the next available size, up or down, and try it again. A large color differance means go at least two full sizes and try again, keep using the same plugs, just clean them very well.


Make sure your timing is set to spec

Also make sure the mixture screws are adjusted properly---turn in until the engine is about to die, then turn out until it just smoothes out, then keep turning very slowly until the highest idle is reached and then lessens by 50 rpm, do it by ear, the slightest change in engine sound is what you are shooting for, do this three times to each side, one side per time per set. This is a good setting so the engine does not want to overheat at idle for long periods.

Then make sure the sync is still set, if not u should do the whole process over after it is sync'd, I had to do the whole operation, start to finish 4 times before I got both sides of the engine to co-operate and run properly--those carbs have not changed from the same design for over 30 years
