mat in tn Posted January 25, 2022 Share Posted January 25, 2022 When I restarted the truck, it ran smoothly again. Vacuum was steady again. Hoping the screw went on out thru the exhaust system. But yes valuable lesson learned. can you imagine the odds of that little screw being beaten to death while bouncing around trying to get through the valve which is only opening 3/8' and not ever being still while open? That would take a lot of luck and a lot of air flow! Link to comment Share on other sites More sharing options...

That would take a lot of luck and a lot of air flow! OK so where the heck is it???!!!! IF I hear it again, I will be removing plugs and sticking my magnet down the hole. I'm pretty sure it went down the driver's side bank from the noise location. And this comes to mind. I used to work on a local street stock race car. We had a roller rocker come completely apart one morning in practice. Back at shop, we pulled the motor, pulled the oil pan and found all but like 3 of the little needle bearings. Called the engine builder, who was a gruff old SOB. HE said "RUN THE DAMN THING! IT'LL EITHER LIVE OR IT WON'T!" I'm kinda there now. It's quit making noise and was running right last time I started it after all this. Apparently the throttle plates got all in the right place to work correctly one last time. I think they had been bouncing around causing my random idle issues that I was blaming on general Chinese-ness of the carb. Link to comment Share on other sites More sharing options...

Gary has one and I bought a similar model, though I can't reference it here. Think Gary did a review on his. Link to comment Share on other sites More sharing options...

Have some to pick up in the morning. We'll see if they are correct Link to comment Share on other sites More sharing options...

I have an edelbrock 1406 carb that came with my Bronco, it was rebuilt by the previous owner and “never worked right”. I switched out for a new one, if you want the old one I would be happy to send it to you for the cost of shipping. It will need to be rebuilt, I have no idea what is up with it.. I can send pics etc… Link to comment Share on other sites More sharing options...

I like the Autolite theory of operation and the chinese carb is a very close replica with enough changes to get by patent/trademark/copyright.
