Unstable idling.

Why do you need larger ones? A new sleeve you can make any size, no? I sent Lund's my old body and slide (throttle valve) and he machined the slide, made and installed a new steel sleeve for the slide and bored the old body to size. Or I'm not understanding. If you have the machine shop it should be easy.

It's easy enough to turn the old slides down. I just turn up a mandrel that fits into the lower part of the slide. Drill and tap the centre of the mandrel to accept a small screw, about 3mm diameter or 1/8" diameter. Hold the slide on the mandel by tightening the small screw into the slide (where the needle would normally fit). Back-turn it, but don't turn off the tang that engages the keyway in the slide bore.

Turn the slide down, so you can press on a piece of stainless steel tube. I used 35 mm OD stainless about 1.2mm wall thickness. There wasn't much to take off the OD to make it fit, so I ground it to finished size.

Hi,
I understood now.

Piero, re-sleeving an Amal carb is not an easy task. I would not advise to try doing this yourself.
The body of the carb must be machined to a slighty larger diameter, and a thin steel sleeve has to be fitted over the throttle valve, after the throttle valve' s diameter is slightly reduced by another machining operation.
There is a guy in this country (the netherlands) who can re-sleeve amalcarbs.
However, this is not particularly cheap, in fact, this is only marginally cheaper than buying a new carb from the UK.
For this reason I would not bother for a re-sleeve operation, and go for new carbs.
