well just did the first major run after the valve job, ran 500 miles, it used about a1/4 quart of oil got 25-26 mpg, everything is good except still hard to start and when it starts it either goes to 1200 rpm or 600 same with restarts when warm, I changed air valve and hoses all vac hoses are goodhavent touched the trottle positioner and I don't think the linkage is a problem anymore what next? thanks for the help so far it was nice ride even had it to 100 a couple of times averaged about 80( only 5 over) so wasn't speeding much
