Carb Jetting

I would start with 140 main 55 idle and I would check to make sure but your main venturi's should be 36's unless someone really de sized the carbs for some reason. I have no experience with the MX version of this Weber but don't know why the main Venturi would be so small. Are you sure they are not 40 IDFs instead of 44's? The 44 IDF carbs came stock with 36 venturi's, 135 main, 50 idle and I think 200 air corr. jet with the F11 emulsion and the 50 accelerator pump. The 65 idle is way too big and I bet the plugs are black and the tail pipe in black inside. People over jet the idle to cover up other issues. The plug electrodes should be chocolate brown in color if the jetting is right. Good luck and keep asking questions.

Thank you Jimmy V , that’s exactly what I thought  and they’re 44 for sure , they used an engraving pen to mark the venturis I will measure, who is a good source for carb parts? The kit came from Amazon and it was for Weber 44 IDA and 44 HPMX Empi

Sorry IDF 44 Empi

The weber IDA is a much different carb than the Weber IDF. I may be wrong but I thought the Empi HPMX was a copy of an IDF which is much more drivable. The IDA carbs are for all out racing and do better at full throttle or no throttle. The main venturi's my fit them both I dont know. Regardless, you will want to run 36 venturis in your carbs to get the full power your 2110 has on tap. I hate to say that the empi carbs don't have a lot of fans. I have heard more bad than good about them in the vane of all the important air passages not being drilled and other quality issues.

At first, the EMPI carbs were a big bag of suck. They had porosity issues, drilling issues etc.

But that was ten to fifteen years ago when they were first ripped off/introduced. The new ones you get today are much better than before. I'd still prefer Italian or Spanish Webers, but the new ones ain't bad.

Sounds like you're on the right track with respect to jets Speedster Danny. I'll echo Jimmy, you probably want 36 vents, measure them, it may be what you have.

Thank you my friend

As a point of interest, here's a few pics of @DannyP conducting a Weber Carb Clinic at the annual Speedster Meets Spyders gathering at 2012 Carlisle, PA.

The Weber Doctor is in...

A group of Weber enthusiasts watch as Danny de-mystifies the Weber function...

The group is in awe and gathers closer as they cannot believe that Danny, has in fact, exposed the Weber sorcery!

WOW! Memories.... RIP my friend Carl Berry, what a great dude. I see Michael, and Lenny, Leon, Paul, Greg, Al and the lovely Heidi, and even Cory........

Is that a pre-IM Marty and Sandy in the left of the first picture?

I think a few of those guys may be dune buggy guys?

Looks like someone was working on some browny points by bringing the teacher an apple. Awwww.

Yeah, I think Carl brought the apple. That was just his way. Sweet, sincere, appreciative, and full of wonder his whole life.
