About 2 summers ago I bought an 86 honda 250R atc a guy had sitting around I cleaned it all up and got It running. The thing ran like a raped ape all summer long and continued to until this last summer about mid way throught it just died on my step son in the middle of ride. The motor wasn’t over heated, it had coolant, oil level was good, and it had good spark. But wouldn’t start. I got tried of messing with it and put it way. The other day I decided to dig it back out and look it over. I took the carb off and made sure that the floats were adjusted correctly, while I had the carb off I read that the reeds could be bad and that if they were i could flip the reeds over and get some more time out of them so I checked this and fond that I need to flip the reeds so I did. The bike started and idled normally for the bike. Started riding it in first gear felt normal shifted to second gear for about 30 seconds tried to give it a little more gas and it just fell flat and died. The bike will not start Back up. The bike has good spark, fresh fuel, fuel mixture is 32:1, the air screw is opened to 2 ¼ turns as my Clymer manual suggest. Waited 10 – 15 minutes just to see if maybe it was flooded, still won’t start. I could use a little help and a few ideas.
