I'm looking forward to all the newly-rich Indian sub-continent millennials restoring Ambassadors and Landmasters and generating a big demand for quality new parts. But not with bated breath....!

If the reproduction things they consider acceptable for other devices (think copied Lister/Petter engines and such) is anything to go by, you'd do better making your own.
Considering you cannot drive a car in Delhi that's not EURO3 or better now, the scope for older cars may remain like it has in places like Hong Kong, minimal at best due to regulations.

It's going to make a resurgence, question is when.

I'm thinking about my brakes again.

The shoes I got are 30 thou' oversize (to account for turned drums) but my drums aren't turned.
So, to fit the shoes on the anchor at the top and not bind, the lower adjustment needs to be far in, meaning the contact patch of the shoes is minimal.

I'm gonna see about reprofiling the shoes so they fit correctly (just take 30 thou' off the arc).

Proper oversized shoes will have the metal oversized too.

You will end up with the braking material thin at each end.

Can't you get the drums ground to +30?

I need to double check the arc.
If it's the same then the material thickness is all that was changed; otherwise yes, I may have to get them ground.

New valves, new fuel diaphragm, new spring, new bushing, new shaft, new filter and all new seals.

Just waiting on the vacuum diaphragm with the alternative shaft to arrive, then if can go back on.

Fuel pump goes GOOIIEE PARP when you squeeze the lever, so that's good.

You must have fitted the diaphragm upside down. They're meant to go PARPIIEE GOO.
