Holley 770 Questions

[Mattsvtcobra]

Sorry for the delay and thank you everyone so much for the suggestions! I have a few follow up questions.

1) mechanical springs in the distrib cap. Just open it up and squirt a small shot of wd-40 on them? Any warnings here? Is there a cleaning procedure, or is it all inclusive and wd-40 only?

2) Carb base plate- What do you think the issue was there?

3) A couple of people have suggested going with a new carb and I think that would be a good choice. I'll have to start walking down that road some and see what the options are.

4) The air cleaner is resting or pushing on the back of the distrib cap. No clue why it is set this way but is this an issue? I'm sure I can find a small riser piece to get it up off of the cap.

WD-40 is more of a solvent than a lubricant. If you're only looking to clean it, then great. Otherwise I'd look elsewhere for a better lubricant.

Have you confirmed the throttle cable is not binding in any way, at any point in its travel? As one who has experienced a stuck throttle in a Cobra I'd look there first.

Not sure why the base plate replacement worked but I can only assume that there was a restriction or leak in one of the bushings or the throttle plates were sticking. I think it cost about $150 to replace the base plate but if I were you, I would Save the money, sell the 770 and get a nice mechanical secondary 750. You won’t believe the difference.

I have tested and looked over it a couple of times. Seems okay.
