BB500...have you adjusted the mixture yet?..the 3mm allan in front of the fuel dist'..its a little spring thingy...you might need to turn it up a little...take the air cleaner off...easier to do that way...clockwise rich...counterclock lean...it will fire with the startup cold valve (shot of fuel)...but be too lean to keep running...you'll need a long 3mm allan to do this...as you have to push the allan down to contact the adjuster...but dont push too hard, just hard enough to feel it grab the secondry adjuster inside ...get someone to help you...get them to startup the engine(keep starting)...till it will run with the adjustments...hope this helps you
