So after a year or so of driving my 64 w/ 4spd I finally beefed it and tried starting the truck in gear w/out putting in the clutch. It lurched forward and I caught it immediately; no fatalities this time. But ever since I've been having a problem with the starter. About 80% of the time I go to start it, everything's in fine working order. But the other part of the time the starter will just whir around like the solenoid isn't engaging the starter gear to the flywheel. Also, regardless of the starting condition, when I let out the clutch to let the rig idle in neutral I feel a slight pull forward as though it were in gear. For the love of god, what have i done to my poor truck?!!
