Mike,I have a QJ,Holley and a pair of AFBs in my cabinet that are dyno carbs and also 2 dist,one with a std gear and one with a poly gear.The last thing I want on a dyno or test stand is a issue!Tom

[HWYSTR455]

The carb that is on there now is the carb it was last on the dyno with. But it's unclear at what the adjustments were on the dyno. Kind of doesn't matter, simple carb adjustments shouldn't cause the 'noise' issue, but it is one factor that will eventually be addressed.

I was informed the carb, due to elevation concerns, was jetted up 2 steps prior to shipping. Not a deal breaker, also wouldn't cause any 'noise', and that will have to be revisited once running properly and road tests can be accomplished.

Yes, the objective is to resolve the rough running issue with the next effort, then the 'noise'.

My comments of 'theorizing' is a reach as well as some wishful thinking thrown in for good measure. Also to point out a potential cause that can easily be eliminated. (Following the process of elimination approach).

You got good help on the way, I have a feeling this will finally be diagnosed soon.

One question: Is the same oil pump and driveshaft in the engine that experienced the oil starvation/pickup tube fall off? If not, at what point was it replaced?

[dataway]

I think if I had the same problem (the noise), and couldn't identify it by listening I would.

1. Turn it over with no plugs and listen ... still makes the noise ... then
2. Turn it over with no plugs and the distributor and oil pump drive removed ... noise disappears, you have a solution, noise doesn't disappear you know there is probably a part clearance issue somewhere deeper inside.
3. Only makes the noise with plugs and running ... figure probably combustion related, then....
4. Check yet again for exhaust manifold leak, crack, exhaust port leak/ crack. No luck .... now you are beyond my knowledge to diagnose.

I'd do it all with no belts installed, and AFTER any tuning issues are taken care of.

This is not a comment about this particular situation at all, just wondering if that would be the proper assumptions to make in a similar situation.

OK, so my misunderstanding. To be clear, the engine ran smooth and fine with this carburetor on it on the dyno. Got it. Sorry to take this off track. I agree with your approach of getting it running right first, then address any noise issue. Again, best of luck.

mgarblik,
This motor hasn't run right with this carburetor in Virginia. I had a Street Avenger on it before. This was the carb that was used on the last dyno.

This approach makes sense.

What’s the deal with this engine? He has reached out to me about mine and caster1 engine builder. I gave him the contact info but I know my builder and unless it’s just a simple fix he isn’t gonna cobble it together. He is gonna tear it down and completely redo it using new parts in place of anything he feels is unworthy.

Any updates?

[Va68goat]

wbnapier,
No updates...been out of town for a week for work. Jeff and Paul reached out to a guy that lives near me thats going to check out the motor. I spoke to him a few times. Hoping he can come take a look this weekend.

Well...I do have an update but I think it would be best to hold off on posting anything until I see how this plays out.

[STEELCITYFIREBIRD]

Hope you boys are able to get a timely, fair and viable resolution to this.

STEELCITYFIREBIRD,
I'm hoping for that.

Steve C.,
Collusion or conclusion? Hahaha

[Steve C.]

Carnac suggests no secret cooperation or conspiracy, especially in order to cheat or deceive.

Was the mayonnaise jar was sealed tight in order to prevent a accidental vacuum leak ?
