Hi recently got a 349 the problem is I can only get it to start, after I have dismantled the carb and cleaned it with carb cleaner then it starts ok over and over, but when I let it stand overnight then it will not kick over and I need to strip it down again clean it and it’s ok for that day but next day same thing, any help appreciated. Cheers

1st are you turning fuel off when stood?? old amal float needles are plastic and are crap! I think there are teflon tipped ones available. Have you checked plug when it does'nt start ? is it wet? It could also be caused by a weak spark as it is more critical from a cold start so check quality off spark by seeing if it will jump 5mm gap. MAKE SURE POINTS ARE GOOD AND CHANGE CONDENSER AND TRY AGAIN. Also final query I think 349 had alloy tank?? if its a plastic one or fiber-glass these are being damaged by ethanol fuels ? I will only use 98 octane esso supreme plus in 2 of my bikes for this reason, check other threads on this forum.hope this helps.
