I'm not sure i know what you mean by set your timing way off?
if your sanding in front of your motor #1 on the distributor should be at 7 a clock, but i like to set en at 5 a clock just makes the wires look better.
and if your running a carb no computer you'll have one of two distributors, one is vacuum advance and the other is mechanical advance, both have about 28degs of advance.
and this is how we time ANY motor that comes in to my shop, total timing, and this is how you do that, warm up the motor and time it at 36degs @ 3000RPMs, then read your timing at an idle, timing should be some where between 6degs to 10degs if not you need to look at your distributor for vacuum advance or weight advance or mechanical advance not working the way it should.
and for vacuum advance you need to pull and plug the vacuum hose only to check idle timing ( not total timing )
i don't know of any profromance shop timing any other way!!!

Sounds like your timing gear is off a tooth. Here's how you check: Take out the #1 spark plug and set the crank at TDC. Check to see if your lifters are loose. There should be some play if it's in compression cycle. If you can't get it to move by hand, the timing is a tooth off. If you have recently rebuilt the engine, check the relatioship between the crankshaft and the camshaft. If these have not been touched, it's definitely the distributor gear. All of this should be in your mechanic's manual. Good luck!

Poll the number 1 spark plug out.
Have someone put there finger in the hole to plug it.
Crank the engine just a tad to get it to turn just a tad.
Keep doing that until the person feels the most air pressure pushing his finger. You might have to do that a couple time to get the most air pressure.
Once you get it their pull the distributor cap off and make sure the rotor is pointing at the number one plug wire.
You might have to get someone that knows something about cars. It doesn't take a genius to do this. It sounds like your distributor isn't set right. Good Luck.

Probably timing chain unless some one took the distribute out and moved it pointing the rotary cap on another spark terminal. Pull number one plug and bring number one up top dead center on compression and see where the rotor cap is pointing or pull the distributor cap off and by hand turn the motor back and forth to see how much play is in the chain . You will get a little play but shouldn't be to much .

Has the mechanical advance mechanism, inside the distributor, seized fully advanced? In a H.E.I. distributor , this scenario is common for pre '80 G.m. engines. I assume that you have a fully ,vacuum controlled,manual advance type H.E.I. distributor that is mated to a fully autonimious carburator fed by a manual fuel pump. If what I believe is true then your engine is being subject to narrow operative parameters not unlike the jeep engines built during the Koerean war-1958 or so.

sounds like the dist. has been installed a tooth or two off.Make sure #1 is at TDC and the rotor is pointing to #1 cyl. It could be timing chain also.

Sounds like ''streched'' or worn timming chain to me. Try running the engine up and down while watching the timming light on the damper. If the timming line drifts back and forth, the chain is too loose, and worn....

The key way on the harmonic balancer should be stright across from 0, It may have sliped. If this is ok, it's the timing chain and gears.

If it was all these other problems it would not run decent at all. You have a distributor problem or a plug wire in wrong hole.

bigley has a good point; that's what generally occurred to me. Is it assembled correctly? Is the valve train indexed properly?
