MODEL 30 CARB TYPE..?

Post by PANASH »

Hello
Can anyone tell me the correct amal carb for my model 30 engined AJS? Haven't checked bore size as only collected bike today so any help really appreciated. Looks to be an old worn out Amal monobloc 928 / R300 fitted at moment, which I think may be incorrect.
Engine is a 600cc (1958) year so believe 1 1/16th bore...just need confirmation before I buy...
Anyway wait to hear back from the experts.
Thanks sincerely
