First off I have a bone stock 61x/61x single carb motor i swapped into my sn last year (650 swap). Engine is bone stock never tore down. Ran great last year, shortned the rear and rebuilt tray over winter. rode it 2 times (just yesterday) this year with no issues at all. I premix 40:1
It will run great on the stand, fire right up without the choke. put it in water, it feels like its running on 1 cyclinder (sometime like it cuts in and out like its about to foul a plug) and if you try to crack it open at all it dies. everytime it dies it wont restart. then ill pull the plugs out throw a different set in and it will fire right up and run good. the second it hits water back to running like crap and die again. i got fed up and packed up and came home. right when i got home (20 minute drive) tried cranking it it no go, so i put the original plugs back in and boom fired right up. I drained the bottom 2 gallons out into glass jugs, no water. no water in fuel separator. I cut back the plugwires about 1/4" and looked good (cut them back one last year from burning out). Took it down the road to a small pond before dark, still ran like crap. it died and wouldnt start. took it home, tried starting it at home without touching it and nothing, pulled the plugs ran inside and looked at them in the light, looked wet with fuel (no water droplets). I didnt clean them or blow on them left them the way they were and check for spark. they sparked so i put them back in and bam fired right up and ran perfect. WTF!!!!
i got pissed so i cleaned the carb to calm me down and just so i could absolutely rule that out lol, it was due had some crap in the filter after the pump. still runs good after that but havent put it back in the water.
I havent checked compression yet if anyone is wondering, but it sounds good and feels good to the thumb.
what do i try next??
