my speedflight starts no problem in the clear weather but when its raining and damp i have a problem starting it end up kick starting but back fires, then when starts fires up then just dies when turn throttle up
it sounds like the carb jets may be blocked,the warmer weather does not require as much fuel to get it to start so if the main and pilot jet are narrowed by emulsified fuel of blocked it will restrict the fuel flow amount and not have a rich enough mixture.check the choke jet to this may well be blocked.
