If you are reading this section you have a Weber Carb or Multiple Weber's that need tuning and jetting or just have Tuning and Running problems you cannot figure out...

This page is for those of you that purchased Webers from someone else that likely has no idea what they are doing or simply does not have any form of tech or after sales support. Maybe you bought used Carbs. Many have bought from eBay sellers, and others that simply sell the product with no care that you may need help or even sold you the wrong kit or did not sell you everything you need and you are at a loss how to make it all work...You may have bought a Car with a system alreday on it and it is having issues...Etc. You get the idea...

If you purchased a New Genuine Carb or Redline Weber Kit from us you are likely not having any real issues or if you do you can simply call / email us or use the Toll Free Redline Weber Tech Line at 1 800 733-2277 Option 3

 #2   Baseline Jetting Service is offered to get you set up with a correct set of Jets and Chokes for your Multi-Carb Dual Triple, Quad or V12 install. We can either sell you a set of proper jets / chokes, etc. and there is no tech fee for this as you are purchasing parts OR if you simply want the baseline jetting reference or range you need ( You already have jets, have a friend with jets, Dyno guy with jets, etc. ) we will provide that for a flat $40 fee.

If this seems like the horrible paperwork you need to do when you go to a new Dr. you are correct...We cannot help without background and baseline info and often when providing the info the problem is found and solved...

Again, More customers than I can remember have spent months tuning carbs when they actually had a dead cylinder or 2 

RPM Range used / desired:

Cam profile being used: 

Ignition System:
Distributor with Points and Condensor
Distributor with Electronic Ignition
If Distributor does it have a Vacuum advance Yes / No      Is vacuum advance hooked up and if so what source is it hooked to ? 
Crank Fired multi coil
Magnetos
Anything else.

If Multi Carbs what Synch Tool you are using:

Air Horns or Air Filters ?:
If Air Filters what type ?

And Finally........
Description of problem(s) you are having with as much reasonable detail as possible...
The reason we ask for all of this is it is exactly what we would be doing here if your car was brought to us for Tuning and Troubleshooting..We will not start tuning on a poor running car until we have done a compression test and pulled the spark plugs and replaced them if not like new...You cannot tune a car with fouled plugs and No, cleaning them with a Brush does not help.
