rcarlisle Posted December 10, 2021 Author Share Posted December 10, 2021 you gotta start somewhere. how far are you from Salisbury by the way? i go there regularly and probably headed there in the next two weeks. I'm building an 83 f100 there. i just picked it up last month and im building the 5.0 for it to take out there and install along with a c6 for starters I'm less than an hour from Salisbury. Or right at an hour maybe. Where are you in TN and what route do you take to get to Salisbury? You may pass right by. Link to comment Share on other sites More sharing options...

rcarlisle Posted December 10, 2021 Author Share Posted December 10, 2021 suburb of Nashville. I'm travelling I40 all the way to Statesville, then across to Salisbury just east of I85 Ok. I'm on the I-81 to I-77 to I-74 route from TN to NC. That passes within 3 miles of the house off of I-74. But let me know when you're heading this way if you might need help or whatever. Btw now and Christmas, probably won't have time, but who knows. Link to comment Share on other sites More sharing options...

Worked well initially with a few idle adjustments. Truck runs great. Ran it up to 80 with more left. It would run that before as well though. But this one shows no leakage unlike the old one. Still adjusting on the choke, though. How hot does the truck have to get to open the choke plate to vertical? I only idled a bit and drove my short lap around the block - 2 or 3 miles yesterday (Sunday) and it wasn't completely open when I got home. The temp gauge was up and moving at least near where it normally runs. I didn't have a lot of time Sunday to fiddle with it. I had set it Saturday to be completely open when truck was thouroughly warmed up, but I drove several more miles and scenarios on Saturday. The whole choke system seems like a lot of adjustments to get all the factors working correctly. Choke plate completely closed, vac pull down, fast idle speed, time on fast idle cam, time to open the plates completely. Pics are on my project page in that section.

There's really no way to accurately say when the choke should be completely off. That's because there are so many variables, like outside air temp, how lean your carb is jetted, whether or not you have hot air plumbed to the carb and if that system is working, etc. So the best thing to say is that it should be fully open when the engine no longer needs the extra fuel. I'd expect that to be when the coolant temp is up fully and you've put some miles on the vehicle. But the real test is how well the engine runs. If everything is set up correctly it should start easily, keep running through warmup, and not have any bogs. Plus, it shouldn't blow black smoke at any time, which indicates too much fuel. It sounds like you have it set just about right. But the fact that the choke wasn't fully off after your jaunt around the neighborhood suggests it might be a tad too rich. Still, the proof is in the driving. Link to comment Share on other sites More sharing options...
LARIAT 85 Posted December 13, 2021 Share Posted December 13, 2021 How hot does the truck have to get to open the choke plate to vertical?

The choke plate *should* be completely open when your engine is at full operating temperature. If it isn't, your [thermostatic] choke isn't getting enough hot air up to it. The whole choke system seems like a lot of adjustments to get all the factors working correctly. Choke plate completely closed, vac pull down, fast idle speed, time on fast idle cam, time to open the plates completely. Yes, and that is a big reason why all vehicles went to computer-controlled fuel injection. But like Gary said, when the choke is set up and adjusted correctly, your truck should run as well as a fuel injected one, even in the coldest temperatures. Mine does.
