Welcome to Miniriders,
Drop in and say hello in our
Introduce Yourself thread too while you're here.
Sound's like the port's or the jet's are still blocked?
When you pulled the jet's out did you make sure the hole's down through the middle of them are clear?
Sometime's you need to poke a single thin strand of copper wire though the to clear out any gum/varnish that's built up from dried up fuel etc.
Also check the hole's that run across the jet's that they're all open/clear, especially in the emulsion tube where the main jet screw's into.
At the bottom of the thread's in the carby base where the pilot jet screw's in, make sure you can see light through to the bore of the carby, if this is gummed up then the bike will be very hard to start, and you'll have trouble tuning it.
And when you have the carby apart, remove the mixture screw and blow some compressed air through the carby, especially the 2 or 3 small hole's on the air filter side of the carb,
You should feel the air coming out one of the hole's in the bottom of the carby.
What sort of carby has it got on it?
And how many turn's out is the mixture screw ?
Are you using a clean foam filter, with filter oil on it ?
Cheer's , Craig
