Be careful not to tip it when you pull it off or the pin that holds the float in can fall out. This especially applies when reassembling it!
The low speed jet affects how it comes off the corner as you roll into the throttle. It's only the first 1/4 throttle. Frankly, you seldom mess with it once set (unless you are running both sprint and long tracks: "long track" = sustained full throttle, like 30-45 seconds or more in 6th gear).
If you pull the bowl off, watch how the brass tube goes down into the body of the carb. It's a challenge to figure out how to reassemble the bowl the first time or two.

I re jetted it today to see if I could do it then I did a few pulls and figured the fuel was vacuum fed so took out the plug and put my hand over the hole to create some sort of seal and pushed the kart around a bit. then I tryed to pull it again and it started right up! I can't believe I didn't mess anything up. Is there a trick to get the fuel back in the carb after you jet it?
Thanks,
Roy

You can put it in gear and spin the axle with the spark plug out. Make sure you leave the plug wire on and ground the plug against the motor to avoid damaging the ignition system. |

I've also seen guys unscrew the fuel return line from the tank, put their thumb over the resulting fuel tank hole, and blow in the fuel tank vent tube. Watch for fuel flowing through the line into the carb and don't overdo it!
I've always felt like it might flood the crankcase if one wasn't careful. It's a lot faster, though, than pulling the plug and cranking the wheel. I tend to do the latter, though.
Or get a really good, young, strong friend with a good heart to push me through hot pits a time or two as I try to start it. <G> I do that when I'm in a real hurry!

| Hey Roy, My name is Bruce and I live in Allenton and work over by Dousman. I've been into a shifter for only about a year and have been autocrossing with Madison and Fox Valley(nice people). If I can help you or pop out ot visit you at he track give me a call on my cell at 262-388-2512. I am still a real neophyte, but I have been digging out every piece of information I can find and I am usually the only Kart at the events. Hope to talk to you soon. |
