I have 2 days riding the new old AMAL
on the bike and when I get off throttle or do and aggressive engine braking I get a blue flame out of the muffler. It is not overheating ie red header or chirpping, ticking after ride or tappet heat noise. It starts well after prime and has smooth acceleration. I moved needle from top to middle and the blue flame became more pronounced as per more fuel loading I expect but same secondary ignition. I have cracked the throttle and nothing broke but need to ditch the blue flame if I expect to go to a filling station safely. LOL! Points gap set no strobe but only changed carb body and fixed points in place no change to timing which was not popping a blue flame. Looks cool after blipping throttle but cannot be good.
