Hi All, I have a 50s side valve ES2 swing arm model it is far from stock but I have had it running and ridden it up the road but it is running really rich and fouling the plug. It has a concentric carb fitted and I have done all the usual dropping the needle height, and judging the mixer screw etc but still can’t get it right. Has anyone in here run a concentric Amal on their ES2 and if so what model, jets etc? Thanks in advance
Side valve ES2, did I read that right? ES2 is OHV.
Yes I have two ES2's with Mk 1 Amal's.
A big bore ES2 with a 28mm with 240 main jet (530 cc)
A Poor Man's Manx with a 30mm with 230 main jet (Standard bore 490cc)
I think both have 3.5 slides but I can't remember needle settings, both run well.
Hope this helps.
