I checked the timing on my race car today. I have a timing light that has the dial. I run 36 total and it was off the dial advanced. It started and ran good. The last run (last weekend) was 10.34 same as always runs in that air. I adjusted it to 36 total (from where it was) and would not stay running. Moved the mark back to about where it was and started and idled fine. The way it was to start with sounds and feels right, but does not show up right on timing mark.
I borrowed a timing light and checked it again and reads the same.
Heres combo:
466 BBF MSD dizzy Comp cam 635 lift solid flat tappet cam, DOVE C heads, etc.
The only thing I have done since last time down track was took off Moroso electric water pump motor and added a pulley to water pump.
Any ideas?
Thanks

timing

I took a look, it is an SFI and feels tight but I know it can still move. It does have a rubber isolater.
Is the solution a new balancer? I have a stock one, would that be a way to check?

get it on TDC and pull the #1 plug.if its up you ok.

Do you run a MSD box [like a 6a or 6al]? If so, you might try a regular, plain jane timing light instead of the dial back type that you have. Later, Billy

Balancer has slipped.

timing

I pulled #1 plug and piston is up, but mark seems off a little (about 3/8" to pass side). I pulled pulley and bolt from balancer and looked at key way and looks good. I would like to race this weekend, I think I will order a new balancer (if don't order now will not get here in time) and see if that works.
Is there any thing with dizzy or ign. box that will cause this?
Thanks

Balancer

OK, I received a new balancer today and the old one matches up. So to me, this means that the old balancer is good?
If this is true, what is the next link in the chain? I did take the time to heck dizzy (MSD billet) and everything looks good. I did see that there is about a 1/16" play between turning crank and moving timing chain/dizzy.
I put the old one back on and will start car and check timing tomorrow. Would really like race this weekend, so let me know what you think.
Thanks

timimg

Ok, problem solved. It was the springs in distributor, I guess they were fatigued. I thought they looked stretched out, so I put new springs on and timing lined up.
This was a crazy thing. Ran TNT tonight and car ran well, 10.35 @ 129
Thanks for they help.

Could you explain the reason for this? I need to buy a new timing light and will buy the "plane Jane" if I don't need the high end one.

Thanks,
Joe

timing light

If you go to the MSD forum it explains the tech. reason for why a Dial back timing light sometimes will not work.
I used both, after replaced springs both worked. If you have a SFI balancer it will have the timing #'s on it.
Good luck
