Just had Weber’s fitted


Recommended Posts

Just had Weber’s fitted to my TR4a

Have been waiting a while due to covid and the kit was a pain to fit, much work required to get the manifolds to fit but the jetting etc was spot on. 
 

Many thanks to Andy Cattani of Classicandrace who was superb, I cannot recommend Andy highly enough. 
 

Apologies for the rotation of the photos

Nice.

Couple of questions if I may.

Did you have them setup for your engine when you bought them and before going on the rolling road?

What jet sizes and emulsion tubes are fitted?

Thanks and regards

The Webers are 45’s model 152G

My engine has 89mm pistons, Racetorations 777/1 fast road/rally cam, ported cylinder head but I’m unsure of the valve sizes and the stage, extractor exhaust manifold and fully mappable 123 ignition.

The carbs came with std jets but included another set.

 

The specs I have are as follows:

Chokes 36mm

4 Progression holes

F16 Emulsion tubes

145 Main Jets  ( replaced the 140 which were std in the carb )

155 Air Correction Jets  ( replaced the 180 which were std in the carb ) 

I hope the above helps.

Brilliant Mike - thanks.

What size idle jets did you finish up with to get a reasonable idle and transition.

Regards

I have read it Peter and it is very informative and it is one of several  sources that has given me a reasonable understanding of Weber DCOE type carbs. I have a setup very similar to Mike and I was interested in the idle jets that he finished up with.

We will embark on the Weber journey later this year with our set of 42s.
