My car has always had a bit of a stumble when you really get on it. Sometimes, it would spit and backfire at full throttle under load, but if you just revved it up while parked, it ran fine. I had adjusted the points, the timing, and everything was fine, so I just assumed it was the stock coil not providing enough juice at full throttle. Today, since it was such a nice, warm ,dry day, I decided to fool around with the carb a bit. It's a Ford Holley 4 bbl, 600 cfm vacume secondary that was on my 84 351W pickup. It's basically a Holley without much adjustment being it's a smog carb. No mixture adjustment, so I decided to adjust the floats. front was dead on, I had adjusted it before. The rear however, was a different story. Somebody had adjusted the float all the way down, so when you punched it, it ran out of gas quickly, if it had any gas in the bowl anyway. I don't know why this was done, maybe to get better mileage by discouraging the use of the back barrels? I took out the needle valve, made sure it wasn't stuck, and adjusted the float untill gas just trickled out of the sight plug. Made sure there were no leaks, then I took her for a test drive. WOW! What a difference! It has always had the git up and go, but now, it feels like a rocket taking off! It needs a bit more rear end gear to really take advantage of the cam, and maybe a higher stall torque converter, but once it's rolling, it pulls harder than a Mack truck! I was truly amazed at the difference. And to think that this carb was on my 4x4 pickup for ten years, and I never adjusted it, it seemed to do fine but I never really got down on it, either.
^My dad did that to my older brothers car when he first started driving,hard to street race when the car wont run right at W.O.T. lol
Good that you didn't find it while gas prices were up, you might of thought of leaving it lol! j/k... good find
Yeah, it's funny when you overlook the obvious. If I could just remember all the stuff I have forgot over the years, I could get stuff done a lot quicker and easier!
