looking for help on my smokey blaster

[dave280zzz]

hoping someone can help me with my smoke problem. i just got my first blaster , two stroke for that matter, and i think it smokes too much. it has a full exhause, fmf powercore 2, no airbox lid and i was told it was recently jetted and the carb was cleaned. it appears to have good compression and is fast as lighting. here are the symptoms for you guys to diagnose, it seems aliright at idle descent response off idle then gets gurgelly then front tires lift off groundl almost. losts of smoke all the way through more when it is under load and spark plug is always black and wet and oiley. im thinking maybe too big of a main jet or the people before me tryed to get it to go fast as possible and i just want it to be reliable and smokeless for my 10 year old . any suggestions are helpfull. also i just bought some maxima smokeless premix and blocked off the oil injection successfully with no change in my smoke problem. thanks in advance ,dave

Yea if the plug is black and oily then the main jet is too big. Get a new one, I believe a 260 or 270 should do it.

you could be running to rich because your main jet is too big or your using to much oil

if the smokless premix and a few jetting changes dont help it, it may be crank seals! are you losing any oil form the bottom end? theres a sight glass towards the bottom left, on the kick starter side of the motor, you may have to wipe it off to check it!

It may be my bad but what size carb are you running and what are the jets in there if there may need to be one if your motor is not to boring out to?? And also what is fast for you??

I really do not know what this person i trying to tell you here , but as for the smoke what color is it ,if it is blue it is burning oil has nothing to do with a carb adjustment , if you plug is all black ,ck the comppresion and see how much you have if not aroungd 120 or less time for a ring job , take the top end off and ck it out , the ring may be bad which is the # 1 thing to do first and with a new set of rings your smoke will go away ,if you cylinder wall is scratched up get it hoaned or bored to a whatever size it cleans upto upto .30 over size maybe more I am not sure how far you can go with the bore size on this but start with the first part here , take it apart and see , it is easy to do yourself , just do it and if you have any questions post or get bck to me ,

what colour is the smoke? if its white, then its your crank seal.
