Well thought I had solved the problem with vacuum hose leak, this morning stumbling on the highway again. Hose is fine not the issue I am wondering if it might be the ethanol they start adding to the gas here in oregon in the winter? If not that, something is up with fuel delivery.

honestly, when I was carbed, I had to readjust everything for summer vs. winter - the other possibilities are a worn-out fuel pump, clogged fuel filter/air filter, and condensation in the gas tank - many products are made to clean the fuel system/condensation out - I would go ahead and try one

 

how are your plugs, ignition wires, cap, rotor? those can cause highway problems as well

Ethanol should take care of any water/condensation issues. That's what HEET and other gas dryers are made of.

 

It's possible that it might be fuel-related, but if it's vacuum it should be most noticable at idle. I would also look at the distributor cap/rotor, coil, etc.

Just re did plugs, wires, coil, cap rotor, both fuel filters less than 2 weeks ago. gonna go pick up some gas drier we'll see it is quite moist here.

You might want to look at your rear filter to see if there is any water in there. If there is you could have a rust hole in your fill tube or vent tube. Just a possibility.

Seems to be fine for the moment, i'll check the rear again, last time got a lil gassy.
