New Webbers clogging air fuel screws

Now there is a good option at a better price. Thanks for that! It would get the air filter out of the wheel wells too.

Those carb-hats are going to choke your engine. They were designed for turbo applications, and are far to restrictive for a NA engine. I made something similar with even larger inlets, and lost 10 hp.
If you choose to do it anyway, make sure you use the lowest stacks you can find. That may aid the airflow inside.

Guess it depends on, what you call mild....
Mine is 2109 with dual 44´s and a web 163 cam. This is the dyno chart with and without the carb-hats.
Again,- you might get a better result than I did, if you use really low stacks. The higher stacks may or may not have caused some kind of turbulence inside the carb-hats.
I did several dyno runs, so I am certain that the restriction was in the carb-hats and not in the air cleaner unit.

These are the carb-hats used. The inlets are 2.5 inch.

back to the original question...recently had issues with new webers clogging idle jets...after many years of no problems.....i believe the problem is caused by the material used on the bowl gaskets....it is a lot softer and more fibrous than the tan colored paper they used to use....and its cut a little more generously so there is more of the gasket edge exposed inside the carb....

clean your filters, grease the top and bottom where they contact the base and top....and use a pair of these....problem solved

I just cant see it being a dirty air problem... I'm running on dry ashfault the entire time. Today I pulled the air fuel mixture screws... shot carb cleaner in there... blew out with air and re tuned. Ran great, drove it for about 1.5 hours and by the time I got home plugged again...

Any one try these??

I haven't yet but will be pulling the tops of the carbs off and cleaning...... I'm just so limited with time I'm trying to enjoy the car while i can before the temp drops....
Man when it runs nice it's such a joy to drive... When it isn't I just want to bag on it as they only time it runs properly is when it's on the main jets 1/2 throttle or better...,,,

if dirty air isnt your problem (as you state) why use the above kit?

Like I said before... Clean the carbs ultra clean. No quick fix here.

Keep them clean.

Your air cleaners look old and almost dry of oil.

Use a couple good fuel filters.

Get used to dealing with this occasionally. They are Weber IDF's.

I used to have a problem with plugged idle jets. After cleaning my right carb 3 times in a week, i did the jet doctor trick. Haven’t had a plugged jet since.
I didn’t use the commercial jet doctors, but made my own from a piece of brake line epoxied in place.

All I have is a 1/2 mile of gravel to the highway and dirt is a BIG issue! Even with just putting along until I hit the black top there is still a coating of fine dust on top of the carbs when I take the air cleaners off.

Not so much now with those diapers the Missus made for me.

I have zero interest in dusting this new engine, that is why the last engine is no longer in the Buggy. I will gladly sacrifice a few HP to have this one live long and happy. Don't forget the HP you lose when the cylinder walls are all scored up and your compression is under 100psi...

Pulled the tops off, spotless inside. Decided to do flat4olsen idea with the brake line while it was all apart.

Edit

Next time I have it apart I'll flip the pieces end for end...... They are a press fit pretty much but I like the idea of them being trapped...Should have looked at flat4olsen's picture first....

Keep us posted please.

Make sure your "jet doctors" don't come out....

This is what happens when you lose a jet holder, same could happen to jet doctor...
