Ok, so I already discovered some metal shavings in the bowl (stuff that snuck in from when I modded the intake ... drill shavings , etc) but I blew everything out, and things have improved, and short of a complete tear-down and re-assy, I'm wondering if this might be indicating a particular circuit in the carb ... here's what happends ... I warm it up, and drive it with no problems, I get on the road and first through 2nd are normal, then when I get into 3rd things seem to bogg a bit, and if I just stomp the petal, it really boggs down. If I am carefull, and feather the gas, it will get up to speed pretty much normal. I'm guessing this mean the secondaries are plugged ... any and all ideas welcome thx!

Acelerator pump most likely.

is it adjusted right, tom in hillsdale mi ajusted mine , pm him and he can send you a adjustment

It sounds just like a clogged catalytic converter.

I'm with Jerry. With the choke open, look down the primary barrel while you move the throttle to fully open. You should be able to see a small stream of gas. If you don't, your accelerator pump is likely faulty. You just need to replace the rubber diaphragm- it's on the front of the carb.

I'd give it plugs and a distributor cap & rotor, then see what happens:rolleyes:

Maybe wires while your there...

Sorry I didn't get back sooner ... all great suggestions, and here is what I can say so far, when the throttle is pulled back, I do get a squirt of gas, and there is no choke, no choke tower even, I have run this way for 4 - 5 mon, no problems ... I did with-in the last 2 mon. put in a JY ditsy when mine started going out. I'm not noticing any erratic tach or anything, but I have yet to put in new plug wires ... plugs are only about 3 mons old. Also I think I can rule-out the snorkel, since I didn't have this problem initially and I have tried running it with just the hose leading to the filter and had the same results. I guess I could go a few miles on the hwy and back with-out anything on the carb, but I doubt that will make a differance. Maybe I will just get a good coil and new wires .. any suggestions for an after-market coil? MSD? I'd like to get the best bang for my buck, but I have no idea what a "good" one costs. Oh yeah ... I have a custom 2" free-flowing exhaust, so no cat to plug and I am pretty sure that the carb adjustments are good, I just re-set them starting with the base-line settings, and I have the air jets sizes 160 and 175 respectively (I was concerned it was suffering from in-ablity to use the extra air forced in by the snorkel at high speed)

Fuel issues are my bet too, fuel pump? fuel filter? accelerator pump? also try taking off your snorkel and running it, maybe your restricting the intake too much. Pull your plugs and see what they look like, is your MPG changing...

 

oh I found some sick hillclimbs north of missoula and got a nice wire feed welder...

Is your vacuum advance on the distributor hooked up?

Nice! I'll have to help you "make sure it works" with the welder :-p ... I have a new fuel filter somewhere behind the seat ... gonna run down the hwy and back with nothing on the carb in a few here ... and I checked the ditsy vac line it's on ... the plugs look pretty good, if anything like things are running a bit lean ... little more grey than the tan or chocolate of perfection ... could it still be the accl pump even tho I get a good stream of gas squirting?

Because your plugs read lean could still be the Accelerator pump.Not getting enough fuel when you are accelerating could be another part of the hesitation.I still think you will need to check things a little further on the carb.Good luck.

Have you checked the fuel filter at the fuel pump?

Is this the one near the tank? I have never changed that one ...

That's the one; everyone forgets about that one. I had one once that had been on the car for ten years (manufacture date had been stamped on it). Car ran like crap whenever I stepped on it. Easy fix (and cheap too); hope it does the trick for you.

Well, that old filter was pretty sad looking, I replaced it, and still no dice ... I'm just about 100% sure that it's just a bunch of debris in the secondaries, because if I'm stomping it through 1st & 2nd gear, no problems it's only when I get up to over 50 mph and I am in 3rd that it has to be feathered ... I just need to take it all apart and clean it thourghly but I did order a new front and back filter from the dealer to have the next time I need to replace it ... no one seems to know the right ones at the parts houses

Well, it was still a bit dirty when I went to clean it thoroughly today, and the only thing that looked suspect was again the incredible deteriorating powervalve ... I think I will just order annother one of them and see if it makes a difference ... I can remember befor when I had some serious problems untill I replaced it the last time (my carb was idleing too high and dieseling alot ... got that fixed, didn't know at the time it was hard on the power valve :-p ) My power valve wasn't as bad as it has been in the past, but it was pretty fragle and crinkled up like a fallen leaf. Gonna see if that does it

...Don´t forget to Check the secondary opening linkage, maybe something are interfering with it...
