So still the same old turbulent flow Emulsion design?

They all do.

:realcrazy:

Now there's an oxymoron. What do they do that makes them high end?

Jets don't work that way. They need to be flowed to verify there flow rates. Its not just about opening size its also length of the jet and entry angles that affect flow rates.

I have the same issue also. You have to get all the difficult bolts on and then tighten them first. In your case go and get some bolts with a narrow head. I've even gone to the trouble of cutting a spanner at the top open to be able to tighten those bolts.

Idle Feed Restriction. If you pull the top off and turn it upside down you'll see where the the fuel travels up at an angle towards the booster outlet. Inside there is a little pressed in tube that should measure 31 thou from memory.

That sounds like the right top. Have you checked the IFR to make sure it isn't blocked or restricted in some way.

If you look at the top near the bowl vents there will be a number

What's the number on the top?

Means nothing to me. Are you sure its a 1972 TQ?

Brook, Those AFB's appear to be different between the first and second photos. Can you post up the carb numbers in the first photos?

That's a lot of initial for such a mild combo. I would suspect its very lean at idle to require that much advance.

I figure it should be doable. Even a regrinding the factory cam to a smaller base circle.
