Lesson learned about Webers

[kent olsen]

I've had webers on my car for 10 years. I've learned a lot from various sources including Harry Beiker and I think I know a little about tuning them.

A while back I bought a jet measuring tool and a cutting tool to open them up more. Well I have been carrying around a box with all kinds of weber jets, emulsion tube, air bleeds and what not.

My car has been on jacks for 3 months while I replaced the left trailing arm. So today I took it out and it was running like I had some dirt in the idle jets. I pulled all the idle jets out of the carbs and measured them with the tool I bought some time ago. Well they were all different. I measured all the jets I had in my box and only a few were the same size as the number stamped on them.

It looks like many tuners start out with one size small jet and just cut them larger until they find the right size for the application, which is what I did today. Finally my engine is running like it's supposed to!!

Kent,

That's great! I have Webers and I really enjoy the throttle response they provide!

That is something that will drive you crazy! Well me anyway.
Also I've seen jets that have been soldered up and drilled smaller.
I've often wondered. Could Oregon be the center of the universe for these types of activities?
Case in point:
My 3.0 was found to have a 2.7 distributor. Yeah with the gear changed so it would run backwards. This proves the old adage, "Anything's Possible".

Interesting. I plan to swap, from my 2.7, the distributor, the hyd chain tensioners, European headers with M&K muffler, and my intakes and Webers.
