Weber K553 carb on a L 134 motor

Post by 1fun51 » Tue Jul 12, 2011 11:13 am

Has anyone had any experience putting a Weber K553 carb on a L 134 motor? I started with a carter and went to a solex and just put a carb kit in the solex and still have issues with keeping the motor running smooth throughout the rpm range. So now I'd like to try my hand at a weber K553 carb but i'd like to know of any problems or of any good things that have came from such a project. I'm reading it requires some modification and I'd like to know what exactly that means before I plop down a bunch of money. Any and all ideas are greatly appreciated.

We have several WW2 Jeeps running with Weber Carb conversions.
The one we use was originally made to use on the Series 3 Land Rover, which is conveniently 2 1/4 litres -the same as an MB/GPW.
It is Weber model 34 ICH
The modifications to make it fit are very easy.
The mounting holes need filing out a fraction to fit the Jeep studs.
I used a gasket rather than the Jeep wartime atomiser
The butterfly lever needs to be reversed and straightened out(as it is cranked)
There needs to be a piece of tubing of the correct size cut to join it up to the air/cleaner horn

The kit is priced in the US at about $150 and is complete with fuel hose, in-line filter ready to connect to the Jeep fuel pump.

It gives very good gas mileage and easy starting right out of the box

Good luck
