Truck feeling like it is under load?

[philo_beddoe]

I guess when i'm bored i'll change it out. I mean ditch the cheap china inline one.  It was there when i got the truck.

Hey guys, I was fiddling with my hot air choke, and was wondering: can choke springs get old and lose some of their travel?
It seems like If i richen the choke enough for the engine to start well, the High idle never kicks off because when the spring is fully relaxed, it has not traveled far enough (though it is close) to kick down the idle. I was thinking about buying a new choke spring, ust wanted your guys' opinion.

You are on the right track.  Begin by replacing the choke t-stat.  And, check the choke vacuum breaks (pull-offs) to make sure they are working and not perforated.  Note that some secondary pull-offs incorporate an air bleed and won't hold vacuum for longer than a few seconds.  Primary pull-offs should hold vacuum indefinitely.

What will happen if you pull that wire off your choke, continuous high or low idle?

No wire on hot air chokes.

Make sure your stat gasket is in good shape as well as the choke tube to ensure your drawing hot air to the stat.
It's not hard to convert to electric choke from hot air choke.

Ok, assuming it was electric...

Hey Guys thanks for the input. The air tube is in good shape. And my puloff holds vaccum. it is a weird system with only one pulloff (ill attempt to show a picture).
I just feel like the spring needs more travel. It either starts good but never steps down, or needs gas to start, but slows down nicely!

Pictures are worth thousands of words!  Replace the choke thermostat and gasket, blow out the hot air tubes with compressed air, verify the correct float level setting, and double check the pull-off adjustment with the appropriate gauge (a drill or ruler).

bd-
I will replace the choke stat today or tomorrow.I also am confident the float is good, I set it when I rebuilt the carb a couple months ago.  How do I check the pulloff adjustment on this carb? I can't find it anywhere.

Look forward through the 1980 Service Manual beginning on page 6C4-6 (pg 644).  Full choke circuit adjustment is described therein.

Got ride of the cheap china in-line fuel filter today, much better. Anyone know how often is best to change the one in the qjet?

[enaberif]

Drop the q-jet one and put a metal filter in made by wix. It is better, larger and provides more filtration than that q-jet one.

[philo_beddoe]

You mean in place of the qjet filter, or external?

[enaberif]

external. the qjet ones get plugged too fast
