Big bore jetting

[NELSON]

YA but is it lean in the top or bottom ? may need bigger main, needle adjustment, who knows?if i was u i would only change 1 thing at a time. other wise u will be spinning ur wheels not knowing the effct of each change

ehh.. i got every jet inbetween 210-300 .. i was gonna start at 300 and work my way down.
its way to lean i know that.. ehh i hate blasters. besides the guy that owns it is very hard to convince.. but he wants it to run right so i dont know.. lol. im just gonna slap some 300 in it.. and go from there..
i was really just wondering about the pilot.. there is no idle what so every.. and its a bitch to get to the pipe.. once your on the pipe its fine..
the other thing is i dont know how old the plugs are.. they said there was less the 1 hour on this rebuild.. but with the plug as grey as it is that must be one hell of a hour.

shit just tell him to get that shit outta there. gonna suck if u pop it. sounds like the main needs to be a little fatter.AND DROP THE clip down 1 notch. is the plug on top of the carb plugged in? this will cause it not to idle also

tors is removed..
yeah idk.. im gonna dick around with it tonight.. gonna go test out this jetski im trying to fix..

go from a welder to a small engine repairman.

just weld the piston to the cylinder and be done with it!

well update on one of the blasters.. im doing 2..

it took a 350 main jet to even get color on this plug.. it runs great.. if you go to 360 it starts to lose it pull. so i back it off to a 350 main.. 35 pilot..

K&N with no lid.

the other blaster has a broke vforce3 reed.. so he has to wait for that to come in.

350 is massive.. the plugs are still coming out more of a gray then brown..
