Need help with a problem.
Otto has offered advice on this, and sorry Otto, it has not cured the problem. I tried a few different types of fuel filters, even ran without a filter and the problem is still there. It's not the carb, as I have taken a known, good working weber from another car and the problem is still there. Same thing with the fuel pump. The problem is, when I accellerate moderate to hard, the car acts like it has hit a wall (imaginary). The motor wants to rev, and I know these motors will go beyond this point, but, the motor bogs. It's a stock 74 low-comp (7.6:1) with points, no Pertronix, as I have tried the Pertronix with it, and still the problem exsists, and a weber 32/36. The car starts, and idles like a champ, the best running one I have ever had, it's just under hard accelleration, it wants to bog. Normal accelleration is marvelous! It scoots a lot better than most cars I have ever had, but, not when you accellerate hard. It does this from a standing start, and running at speed, although it's not as bad, when at speed, but, it's still there. Any ideas?

Namba;
I see what you're saying about the fuel delivery, but, that's why I tried the other carb. I do know that the weber has to be tuned to each car, this I have done on many occasions, but, the exact same problem occured with both carbs. That's why I also referenced Otto in my first post. The motor is getting the gas. When it bogs down, it's still running, and the more you accellerate, it still gets fuel, but, it's like some tremendous hand holding back the car and it sounds like the motor is sucking itself inside out.

Otto, et-al;
I'll look into each of these answers. It just a shame, as the car runs so good, and as you stated Otto, "gradual" accelleration is great, it's the hard accelleration where it comes in.

BTW, it has a weber 32/36, and I swapped another weber onto itand as stated that each weber has to be tuned to the individual car, there should have been a difference, but, there was none.

Well, I hate to have to shoot down the exhaust theory, but, the exhaust is new from the manifold back to the tip, with all new parts. This problem was happening before I got the exhaust redone.

Otto;
I have not checked the jets on this carb, as it came with the car when I bought it. As for the other weber, it's on my GT, with big valve head, 9:1 pistons, sport cam. The one on my GT NEVER did this. It would pull STRONG to redline, not anything like what my Wagon is doing. But, I put this carb (GT) on my Wagon and the problem was still there. I'll have to check all this info this weekend, as by the time I get home, and do all the other husband/father things, it's bed time for this old f**t

I did notice yesterday, when driving home, when accellerating hard, and this problem would start, if I backed off just slightly, you could feel the car jerk a very litle amount, like it's trying to correct itself and actually almost want to pull, but, still not doing it.

If you hear a loud noise, and see a second bright glow on your western horizon, other than the sun, you'll know why. Seriously though, I'll try the safer answers first.
