Won't Idle until warm
Hello - I have a 81 c10 with a 350 that was dropped 30K ago
One thing that I am having trouble with that the car will not idle until it warms up. I have to rev it a little bit for a few minutes before it will idle... we're talking Seattle weather too around 30-50 degrees lately. Is this normal? |

Re: Won't Idle until warm
it sounds like your choke is not working.. What kind of carburetor do you have? it probably has an electric choke? it may just need adjustment. Let us know what ya have and we can tell you how to adjust it.

Re: Won't Idle until warm
Take your air cleaner off and see what the choke dose when you pull it out, it should close off the front two openings. Take a pic and post it.

Re: Won't Idle until warm
Looks like it may be a manual choke, and it is just jury rigged. If so you need a cable so you can operate it manually in the cab.
Also looks like your throttle return spring is stretched waay too far and you have one of those cheap glass fuel filters. Both are not good.

Re: Won't Idle until warm
I picked up an 84 that had the same problem. Choke linkage was jacked up holding the choke open all the time. I fixed it and it starts right up on days where we were well below freezing and close to 0.
If that spring going from the throttle linkage to the front of the engine is your throttle return spring, you need to get it setup right and get a dual spring. It looks like it's going the wrong direction also. Not sure what that setup is. The electrical tape wrapped around the linkage by the vacuum secondary diaphragm also has me concerned. I don't know tons about holley carbs, but I'm pretty sure that's not a standard setup by any stretch of the imagination. Matt |

Re: Won't Idle until warm
That rod/electrical tape mess is holding the choke totally off. It is a manual choke that just needs a cable installed to work properly. When the choke is working, you should not have to fiddle with the throttle to get it to idle.

Good eye longhair... Wow you guys really know what you're talking about. I took off the air filter and 'crappy tape rod' and it looks like this So... I need a choke cable (and housing?) My autoparts store should have this, yes? In terms of hooking it up..Are one of these a choke handle/puller? I would assume that it needs to go through my firewall... would it go through something here? I am a super n00b and this is my first real 'running project', asside from my motorcycle/motored bike projects... so thanks for the help so far |

Re: Won't Idle until warm
Your local parts house should have a choke cable kit in the HELP section. You can run the cable through the grommet on your firewall by the distributor that all those wires are running through. Try to make smooth turns (avoid kinking it) when routing the cable into the cab to ensure smooth actuation. Here's a pic of where I mounted my choke cable, you can see it on the bottom of the dash right above the shifter.

Re: Won't Idle until warm
OK! I got it, went to the auto store and got the cable. Just installed it, and can't wait to put it to the test.
I've only had this truck for about a month now, and I'm learning new things about it everyday - for better or worse haha. THANKS GUYS!! |

Re: Won't Idle until warm
You should also get a metal cased fuel filter too, 'cause if that glass one breaks your whole truck could go up in flames.
