Does anyone have an accurate measurement of how thick these carb spacers are supposed to be on a Jalpa? They look identical to the Weber spacers I have on my Maserati 4Porte. However, from the looks of the Jalpa parts manual, it appears there are (2) of them glued together. Is this true?

Hi Mike,

can't say I ever thought to measure a spacer. Reason is these are as ypu say standard phenolic blocks from Weber. The purpose was simply to provide a seal at the base, and more importantly insultate the Carbs from heat transfer from the intake manifolds that might lead to the daily problem of fuel bowl boiling (vapor lock) and the even worse issue (long term) of Carb Base Warping..

Ask Valtellina Automobili or Evans, Valtellina made major Service on 3 Jalpa engines and should know...

Thanks guys, I'll ask around.

It seems to me that I remember Terry (at Ultimate Motorworks) saying that Lamorghini actually bonded 2 of the spacers together to avoid some kind of clearance problems with the throttle linkage or something like that....

I'll call Evans and see if they know for sure and let you know what I find out.

Not directly related to the topic but I didn't want to open a new thread.

Since my Countach is ready I brought my Jalpa for carbs overhouling and tuning, I was really surprised how clean the inlets were...

You can see only one of these bakelit pieces.

I had my car in for a basic service, oil, coolant flush, brakes, hoses, gearbox etc and since then it has been more and more difficult to shift when approaching a stop. To the point that at a stop it won't get out of gear. My thoughts were, either he didn't put gear oil in, engine mounts, (they looked good on the hoist), or clutch.
Any thoughts fellas?

That's 99,99% a broken engine mount, check the clearance between the cylinder head and the right suspension dome, if there is no gap the mounts are broken. I had exactly the same on my car...

My carbs were back together in the car and tuned, my mechanic found two swimmers with a too low float level, no wonder the car ran not good at high rpms...

Today, I picked my car, awesome how it runs now...
4000rpm off the throttle, slightly press - immediate reaction, full press and up it goes.

Good advice for all, if you have never taken the carbs to pieces buy the carb kit on ebay ($69 for all four) and do it, you will not recognize your car again once it's perfectly tuned.
