- - 460 initial timing (http://www.clubcobra.com/forums/429-460-engine-talk/82929-460-initial-timing.html)

Hey Tom thanks for the sledgehammer. If I didn't say before I am a novice. I havn't really pulled wrenches on a real motor since high school automotives class when I rebuilt a 396 for my 67 Firebird. I am reading everything I can about this motor and it's components. And I am trying all kinds of things to make it run better. I listened to Tom Kirkham and appreciated his advice. I read BG's carb sheet but before this I had allready tried most of this. I have been retarding my timing incrementally thinking this would help my hard starting but after reading BG's site I advanced my timing quite a bit which helped a lot, I richened up carb which helped a bit. But, it smells real rich too. I smell like a gas station when done driving her. I still get a bit of run on and hard starting when warm but at least no more backfire. I guess I still havn't found the magic combo yet. I will keep playing. I wish I had ports on my pipes to check A/F mix. Where is the correct place to install them ?
Hey scooter where did you install the bungs in your pipes. One ? to everyone though. Scooter installed a BG carb and bungs in pipes to get A/F mix correct but he still has run on. Why is this? could timing be that tightly critical ?

Brent,

Since you asked nice :LOL: I've put photos of the bung locations for my O2 sensors here:

I have a pair of bungs in each side, one for the EFI (that's another story...) and one for tuning.

BTW, a strong gasoline smell possibly causing tears in your eyes is usually created by an engine that's running too lean, not one that's too rich!

Use an air/fuel meter to be sure...

Hope this helps,

Tom

Thanks A lot Tom
That is excellent!
Your one smart fella. I turned my A/F screws out and as I said before, increased my advance and now the engine fires right up, doesn't smell as gassy either. But, I still have run on ?

Thanks
Brent
