Okay, so Eric, Mike, Kopecki, and Kevin were all really nice and stayed out at Rudy's with me for damn near an hour and a half helping me tweak the timing and the carb on the Beast....so, now it starts -better- and definitely runs a whole helluva lot better (ie. its not condemed to the driveway anymore), but running at higher speeds (starting between 35 and 40mph or so) the truck starts to shake; the faster I go, the worse it shakes. WHat I'm not sure is, is this an engine problem, or is it possibly something else (such as, I know the hub on the passenger side refuses to seat properly and has been slightly loose for sometime)??? Ideas? Anybody?
