1972 Float Adjustment ...

[Mark Maras]

I hope that works, that would be great. If not, you could try sticking a toothpick down the hole until you hit the fuel surface and then mark the toothpick at the top of the nozzle or the top of the brass sleeve that holds the nozzle. Measurements don't have to be in the thousandths, Mm's would be fine.

Just hope toothpick doesnt fall in the hole. Ill set it back to 2.5 turns clockwise and measure. If its not there should i bend the tab more?

[Mark Maras]

Even if the toothpick falls into the hole, it will float. There's no need to reset the mixture screws back to 2 1/2 as long as we know how many turns down they are during the measurement.

[jalexquijano]

It doesnt even get the toothpick wet at the meaurement shown at 2.5 turns clockwise.

[Mark Maras]

 That doesn't help. I don't know what your reference points are. let me put it another way. However you can do it, the measurement that would help us, is the distance from the fuel surface to the top of the tube that the nozzle slides in. The brass tube surrounds the nozzle. BTW if you turn the mixture screws CCW, (Jalex's term for leaner), to zero turns, the tops of the nozzles will be even with the top of the brass tube. I would think it would be easier to get a measurement with the choke lever pulled all the way back which pulls the nozzles all the way down. If you can come up with that measurement, we can all get back to the unsettled, at least in my mind, question of the proper float height , and as C. O. brought up, how critical is the float level in SU's? We can also eliminate one of the cold sputtering causes.

Choke cable was not well adjusted only front carb jet went down. Now fixed.

@jalexquijano OK. If the engine is cold, fire that baby up and see how it runs now. Take it for a ride and report back. I'm on the edge of my seat.

@siteunseen Tick Tock, Tick Tock. As the official timekeeper, how much time do I have left?

All of it! You've been so helpful to all of us, especially Jalex, you take all the time you want. Just so long as you're in Atlanta this fall. 8^)

Told juh.

Those things are tough to get right. I made marks on mine so I won't have to go through that again.

I hope I'm not speaking out of turn, don't know what CO's thoughts were and I value those very highly, but in my opinion not too critical.

He figured out the cold sputtering I hope. Choke cables must work their range up and down for the nozzles to work right as they affect choke.

[Mark Maras]

@siteunseen At least one of the questions has been settled in the churning cauldron of symptoms and trivial facts that I call my brain. I was almost positive that it had to be too lean when it was cold, but then that creeping doubt set in.

 @jalexquijano Good job finding that loose clamp. We could have beat our heads on this cold sputtering problem for a long time and not gotten anything except a headache.

So should i open both front and rear float lids and keep on bending the tang more or should i test the car now that i adjusted the rear carb choke cable?
