Jrpontiac Shop Shark J Joined: Oct 2006 Posts: 163 Spokane, WA	Update. Checked compression - 125, 135, 130, 130, 130, 135. Great. Got engine tdc with rotor pointing to #1 wire. #6 cylinder valves are overlapping. I think that was what I was looking for. Do the mechanical advance springs wear out? Mine looked fine but maybe. I keep coming back to a carb issue but I have been down that road quite a few times and my new carb is so nice and clean and new.... new fuel pump, lines, filter, etc.. and my distributor is nice with new parts. This sucks. Jason 1946 GMC COE 1967 Pontiac Lemans Convertible http://s1275.photobucket.com/user/jrpontiac/library/?sort=3&page=1
