Can anyone tell me where I can purchase chrome plated brass slides for AMAL carbs.

I am, as usual, missing something.

I think I'd prefer unchromed brass slides.

Never had any experience of plain brass or any slide other than std. but since I fitted new bodies in March and added Chr brass slides I've put 550 miles on them and just over three Roadster tankfuls. Couldn't believe it but each 11 litre fill takes me 170 miles so I am getting close on 70 mpg (Imp). The old carbs even when new never reached better than 62 and that was with lots of easy running. The bodies are from new Burlen tooling and other than replacing the needle jets and fitting chromed slides the only difference is the way I ran in new rings. I went for the hard break-in first 100 miles and have run it harder since then. Time will tell if the rings and bores last but it didn't use any oil.

Get chromed brass slides, they are better.
I have tried brass slides on some monoblocks and they didn't idle or last that well.
Chrome is harder, which avoids the two similar metals 'picking up'.
RGM motors, UK do them, as well as new carbs.
IF you fit chromed slides into old worn bodies you will still not idle.

I had Mike Gaylord in Oregon resleeve my original 932/19 932/20 carbs in 1998 using stainless over the original zinc metal slides. They have over 24,000 miles and look as new. I keep thinking there must be some improper mixture adjustment as this '72 750 combat gets 55-60 mpg (US gallons). The bad news is Mike is now retired.

Not all Amal "chromed" slides are actually made of brass.

Some chromed slides are plated standard slides, and I fitted those to my 850 Mk III's carbs.

Here's an Amal I had bored and sleeved by Triton out of Canada.

I know they turned off their website but I heard that if you call them they might still do the resleeving.

The only reason I went there was at the time the exchange rate was favorable and I think it was something like US$65 per carb.

Website is at http://www.tritonmachining.ca/

I think this is different than his previous URL.

I had a set of carbs done by Bruce also and they have been fine. I cannot say enough good things about his work.

Thanks! Updating my bookmarks now.

At $65 per carb it's a very good price. He states brass is used because of it's similar rate of expansion to the pot metal.

RGM - Although RGM advertises chrome brass slides they do not carry them. Thought that was strange as I found out after putting in an order for a pair.
