when you set the timing turn the top cam gear until your rotor is lined up with the cylender number 1 posistion on the cap. Then you put your engine at TDC. use a screwdriver just to be sure. You can have the timing marks lined up and it still be off. If you need to, pull your valve cover and check the cams while they're rotating. You can see pretty easily whats off if you do it like that and crank it over by hand. If you need to take the head off, just pull the whole damn engine. Its so much easyer that way.

distributor is at 1. when the engine is at top dead center, but the intake valves are retarded when i do that and open during compression.

Id pop the VC off and see exactly what the cam lobes are doing w/ respect to piston position. Pretty quick and easy too.

the cam pully is twice the diameter of the crank. so when the crank is at TDC every other time it it hitting where you are telling me to move the cam. So there is no point.

Anyways. I HAVE THE BITCH RUNNING.. CORRECT COMPRESSION IN ALL FOUR CYLINDERS.. BUT I THINK IT IS ONLY RUNNING ON ONE CYLINDER. IT IDLES INCREDIBLY ROUGH, AND THERE IS A "ROCK" IN THE ENGINE (WHICH WOULD MAKE SENSE IF IT WAS RUNNING ON ONE CYLINDER. ALSO TO BACK THAT THEORY UP, I PULLED THE PLUGS, AND 1, 2, AND 4 CYLINDER PLUGS ARE BLACK. AND 2 IS FINE. ANYONE HAVE ANY ADVICE? IM THINKIN FUEL PROBLEMS.. BUT MAYBE N OT.

?? well i think its firing, because the plugs are black with soot, but i could be wwrong.. what kind of ignition problem? like no spark? or bad timing? i advanced and retarded the spark timing a few degrees, and it did nothing.

Re: +Rebuild, But Now No ComPreSSioN==

oh, and if it helps, i'll try to bring the rpms up to like 3500rpm when i took it for a spin around the block, and the power feels like its running on one cyl, and just cuts out. so that's why i think its a fuel problem. any ideas?
