weird starting issue
I'm not sure how to even explain this issue as it's very weird.
most time my truck starts amazing for an old carbarated truck (even on cold days and not having the choked hooked up) but some times it has a hard time starting and if it does start it spits and sputters and some times quit the only "cure" for it is to rev it till it "clears up" and then its fine....it's very weird and I would like to get it fixed so ppl don't stare at me when I start it up and have to rev it to get it to run right lol.

Re: weird starting issue
any time when it feels like it of course. like some times it when its sat over night it will start up like it was just run the next time it runs like a bag of SH*T. same with when its warmed up.

Re: weird starting issue
Why is your choke not hooked up?

Re: weird starting issue
Oh, have you thought about putting a manual choke on?
Is your trucks choke controlled by power or hot air?

Re: weird starting issue
I'm not a 100% sure but I think the easiest way is to find a manual choke carb, then run a choke cable into the cab. Though I think you can get a kit to switch you electric choke to manual.

Re: weird starting issue
what year is the truck? as if it has the egr it may be open at the wrong time (sticking) or may be plumb wrong vac at cold not hot off of the thrmo swicth. just my though as that is what mine did and i too have the choke wired open starts fine and will run fine after a few seconds on a high idle.

Re: weird starting issue
Do you have the Rochester q-jet,that has the electric metering solenoid on top? If so,you'll want to replace the carb with an earlier one. When the solenoid screws up,it can cause the problems you're having,or worse! A new solenoid(if you can find one),is expensive and difficult to tune in.Mine went bad,and I used 3/8 tank of fuel to get 2 miles home!Had to change the plugs,carb,gasket,oil,and filter!
