It does advance smoothly when revved. That's the right timing and valve adjustment. All these things sound pretty good. I'd make a point to get down to a hardware store and buy a pressure gauge and some hose/fittings so you can check/adjust the fuel pressure. Your 71 should be right around 30 psi. You might also want to try to do a compression test to make sure that there isn't some fundamental engine problem. You can lift one dist wire at a time to make sure that each cylinder is contributing to the running of the engine. Pull out the SP wires and feel in there all around to see if there are mouse nests which might be blocking air flow. Are the plugs reasonably fresh? How do they look? Have you changed the oil since you fixed all the things above? - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------ To unsubscribe, E-mail to: <type3-off@vwtype3.org> For more help, see http://vwtype3.org/list/ </x-charset>
