Problem solved, reset the float on the carb and no bucking. I think that after adjusting the valves and loosening the 3 that were tight did the trick, maybe they needed to reseat themselves because I did a vac test and the reading came up to 18hg. Just adjusting the float would not have effected the vacuum reading. Thanks for the help.

I am going to pull the fuel filter in the AM then I will test the pump. As for the ignition A friend put it in his scope and all was good.I guess the thing that really puzzles me is the vacuum gauge reading of 15hg because last summer it was at 18-19hg's and I did not drive that much last year. I a, worried that something is going on with the engine and I do not know what.

bucking would describe it. There was an exhaust leak and while I fixing that I checked for a blockage and nothing there.

new to the form. I have a stude 259 v8 that I can not figure out what is wrong. On a flat it runs good but climbing a hill it struggles. What I have done so far is a rebuilt carb, reset timing, adjusted the valve lash. The electricals are good because a friend put it on a scope and everything checked out good. When I put it on a vacuum gauge I get 15 hg and the needle holds steady which puzzles me because last year I was at 19hg. When I did the valve lash adjustment #5, #7 and #4 rocker arms were tight to the point of stuck. but managed to get them loose and adjusted them. After the adjust the it had more power but still struggled on hills. Any advice would be appreciated
