I have a 1980 Honda 110 3 wheeler that occasionally runs? I get spark, fuel appears to good I even tried starting fuild into the carb and cylendar and sometimes it starts and runs strong no problems however after sitting for awhile I try to start and no luck my shoulder is sore. Is there a trick starting?
The rubber fitting from carb to airbox is missing. However I read somewhere people where taking them off and getting better perfomance. I wonder if this is the problem maybe the engine needs the restriction when starting? does anyone know? Any insight would be appreciated.
Well could be a few things. Could be getting too much air/not enough fuel. I bought a cheap radiator hose for a car and cut it in half...works better than most hoses made to fit. Have you cleaned the carb? If not...its a must. I also suggest an inline fuel filter. I never drive my bikes on reserve just to be safe. Could be a few other issue but those are the most common. Try choking/half choke. If it will not start unless you use starting fluid, its prob a dirty carb. Best wishes.
So you have no air cleaner at all, just an open carb? I agree, your carb definately need to be cleaned plus its probably lean. Performance gain?? Sounds like the opposite to me. Put the airbox back together and with an airfilter.
