timing
ive got a 350. with an elecrtronic ignition,bored 30 over,272 cam, im trying to set the timing and i put a timing tab on it and put white out on the mark on the harmonic balancer and the mark will be an inch away from where it needs to be and ill turn the distributer and it will get closer to it and then it will die ill have to floor it to start it and it sounds like crap. is the distributer off a tooth or something. any ideas
thanks, sonny

Did you bring it up to TDC before you marked the balancer? or did you just install the pointer and mark it where it was at then? Cole

Next, if you are using a vacuum advance, it needs to be disconnected and the vacuum line plugged.

As Cobalt said X2.
 Also it may have a 'timing' connector that needs to be disconnected. Depending on what vehicle this is, will help us diagnose your problem better.

i have never done this before there is only one mark on the balancer. it is a line going all the way across it. i had it lined up with the timing tab.which is set at 4 degrees.it is a 1965 chevy pickup. it has no harness only the wires it has to to start it. i am not sure what year the engine is. it does have the vaccum advance. i did have it plugged. but do i plug the carb where the hose was connected. and is it possible that the timing gears are mabe one tooth off. i assumed the #1 piston was at tdc when the mark on the balancer was lined up with the timing tab. i stuck a screwdriver in the sparkplug hole and it was touching something i believed to be the piston. i just got the truck a month ago. im only 18 so if i sound like an idiot its just because im just getting into this. Thanks

Sonny;
 We are just trying to help.First, and foremost, find a manifold vacuum source, and plug in your vacuum advance to it. Your idle speed should raise, and smooth out, if not the vacuum advance is bad. If it still has 'points and condenser' check the point gap, or dwell. This will change the timing. Always adjust it first, then adjust your base timing. Put the screwdriver back in the #1 cylinder, and watch it's movement as you turn the engine over by hand. The lower the handle drops the higher the piston is. Remove your distributor cap, and turn your crankshaft over by hand both ways. Watch your distributor rotor for movement, it should move almost instantly with the crankshaft movement. Watch the timing marker line on the harmonic balancer, to see if it is anywhere close to #1 at TDC. Just my 2 cents.

The test of turning the crankshaft, and watching the rotor, will tell you if the timing chain, and or gears are worn out.
