Need help to set idle

[Charlie ny]

I kind of see gaskets or washers under the jets too ,BIG no no....no gaskets or washers
under main jets.
I do hope you find the 'V' style nozzle bars.
Failing the above try blocking the small vent hole that you see in the nozzle bar
adjacent to the idle tube.......this would be under the category of experimenting.....
so do not do this on a permanent basis. This worked for me one time a long time ago.

Good eyes Mart - they are little black gasket seal thingys (not sure what they are called). they are soft - not washers. They came with the carb kit but it doesn't mean that I have it right. thanks.

Oops - charlie thank you - none under the idle side of the spray bars either?

[Mart]

The thin black gaskets go under the spray bars, both sides, 4 locations, like you have them.

I think you would have some back firing if your MF gasket was gone ,I would try another carb .Ted

The nozzle bars you pictured are for the 2100 Carb.

Considering the couple issues found with your carb based on the pictures, I'd try another carb as well too. It's a quick and easy check and will answer a lot of questions. You may have more than one issue that you're fighting with. If a loaner carb fixes your idle issue and you're low vacuum then you have your answer. If a loaner carb fixes your idle issue but still have low vacuum then you've got things whittled down to a manageable level.

Update time. The main source of the problem is a sticky and leaking throttle shaft. Complications were a small leak in the inlet manifold. No vacuum to the distributor, and numerous small faults in the carb itself. I'm just organising for a replacement base now. I found it by accidentally jamming the throttle butterflies completely closed and all of a sudden the vacuum jumped up to 20" and the idle mixture adjustments started working properly. In the meantime I also have a new inlet manifold gasket, nicely painted inlet manifold, replacement V belt of the correct length this time, and a nice new shiny vacuum feed line to the dizzy. Thanks to everyone for your guidance. Not a hope I would have got there without the support from the people on the forum. Pictures of the offending article attached.

PS: Anyone know the thread size on the small vacuum port on the manifold riser?

Get a new oversize shaft ream the base and you are good to go.
Most used ones are worn and finding a good one will take more time then getting the old one back in shape.

Temporary fixes in place and dead steady 19.5" on 600rpm - tried to upload a video of it idling I was so happy but don't think we can post video's. Thank you again to everyone. Just some spare parts to find and fit now and all fixed.
Regards
