Amal carb rebuilders

Recommended Posts

I have a pair of Amal 76/187's from BSA's 1938 350cc B.24, 25 and 26, both of which need parts and rebuilding. Does  anyone know of anyone in the UK that rebuilds these carbs? I'd like to keep these because they have the vertical stud pattern and the reproduction carbs have the horizontal stud pattern and I 'd rather not use and adaptor and keep as much period original on the bike. They were found in a basket case 1938 BMW R12 project I have.

Thanks

John

Martyn Bratby still does very good work, takes some time, but worth the wait, no email or computer, Ron will have his phone number handy? below a carby he did for me.

Thanks for the responses. I took the carbs to Michael at Surrey Cycles. He is going to get the missing parts together and get them to Martyn  to work his magic on them.

Best to go straight to Martyn Bratby on 01543 572583.

Amal won't refurb your carb. They will sell you new parts or a complete new modern carb. Surrey Cycles and Hitchcocks are selling new Amal products too.

Yes, and Martyn doesn't like the quality of their parts..... he makes his own, usually cheaper too.

Cheers,

Seeing that BSA B 26 was mentioned in first post I thought I might show mine off here, not military I know but for a 1938 bike it performs really well even in today's traffic and I love it.

Lovely bike. Can you tell me which type of Amal is has. According to references it could be a 76/187. Is the head inlet stud pattern horizontal or vertical?

Hello John, the carb is a 6/187 I believe, (I can't get close enough to check the number) when I found the bike it had a standard carb with horizontal fixing holes using an adaptor plate which looked awful so I bought a vertical fixing carb off ebay which looks and work great.

Never quite understood why BSA used the horizontal carb on these models, maybe because they were early OHV engines and room for the cables under the tank was an issue.

Float level is also very important mine runs best with slightly lower level.

Was the horizontal carb to avoid fowling the magdyno? Some makers used a long throat carb to get past the magdyno. 

For instance when BSA converted the standard coil ignition C11 to magdyno for the military version for the India office, They swaped the carb for a horizontal type, simply because the standard carb wouldn't fit any more. Ron

You are right Ron the mag would foul the carb and of course there were many makes of bikes which had inlet manifold extensions.
