Yup, I'm still here. I was trying different rod and jet combos, had it running OK but no economy gains, when I it started to run out of fuel (I think - based on the fuel filter at carb going empty) and lose all power after about 30 mins of driving. It would idle fine, and after about 10 mins with engine off would run fine again for awhile.
I did some tests and decided to put on a new fuel pump. That didn't help, so I stopped trying to figure it out and took it to a couple mechanics for that problem and a few major suspension and drive train problems. It needs some love as they say.
In the meantime I did put the groove on my Buick terazza van.
It seemed to increase power a little, but not economy. I'll find out soon if o2 is working. .
