Carburator issue. I think

This is the THIRD time I have said it. Read post #21 & perform the simple test!!
maybe YOU need to read post #34

because you clearly can't be bothered to read anything that's not your own blathering i've quoted it for you:
I have tried wot on level roads and it does not buck doing that. It is only on rather steep hills
 
Here is comparison on how the atmospheric pressure pushes the gasoline into the engine, as the engine is creating less atmospheric pressure (suction) as it is drawing air into the engine.

Same as sucking liquid through a straw, reducing the atmospheric pressure that is actually pushing the liquid through the straw.

Now figure in the particular aspects to your situation in the mountains and long steep roads.

First there is a lot less atmospheric pressure at 10,000 feet in the mountains to push the gas into your engine than the 15 lbs per square inch at sea level.

Now along with that heading up a steep slope with the floats out of whack, set too low to build a reserve of fuel in the fuel bowls. Along with the angle of the slope, the gas may be coming up short to even enter the jets where it gets drawn into the engine.

So in the thin Mountain air you are loosing 5 psi of atmospheric pressure right off the bat, to push fuel into the engine in the manner that it was designed to run.

i'm beginning to suspect that you don't understand how an internal combustion engine operates at all.

Now along with that heading up a steep slope with the floats out of whack, set too low to build a reserve of fuel in the fuel bowls. Along with the angle of the slope, the gas may be coming up short to even enter the jets where it gets drawn into the engine.

this is the only (partially) correct or true portion of your entire post.

so congratulations on at least getting something right.
 
Okay, carb looks good and is still having the issue on long hills in Pennsylvania. (I was born and raised in Waynesboro PA).

Let's think what else. Transmission slipping? Torque converter on its way out?

An engine can change the atmospheric pressure?

No. No no no.


Everything to do with the flow of gases and fluids works according to DIFFERENCES IN PRESSURE. The absolute pressure does not affect how much fuel is metered or how much air is drawn in. Only the ratio of the pressures. At altitude, all pressures are reduced by the same factor.

The only thing that altitude effects is the air density, which affects the burn rate and burn completeness because the number of molecules per volume is reduced.

look Einstein, if i wanted somebody to teach me about science i wouldn't have dropped out of high school.

i only operate on full falsehoods, incomplete data and half truths!
