Amal 36mm MK2 baseline main jet settings

Fast Eddie · 2026-06-13T05:05:04-0600

Can anyone assist with baseline main jets settings (just to get me started) for 36mm MK2 Amal’s on a 1007cc stage 3 Maney motor, 11:1CR and a Maney 2:1 pipe?

Acotrel… please do NOT respond…

Kinda thinking that engine and exhaust is not very common for the members on this site.

Anyway maybe Andy Molnar knows something useful since he sells parts to build similar engines.

Well my current guesstimated start point is 330s…

If Mikuni is a copy of Amal, which I find hard to believe, the standard jetting is listed on the MAP Cycle page for 36mm Mikuni carburetors. 310 is the main jet listed for the VM36 Mikuni. 330 sounds like a good place to start though for a larger displacement engine.
