ok im new here and i figured i would come ask ur guys opinion... i got a bike, not sure of the brand, with a pantera 90cc motor in it. it used to have a 125 but the previous owner got rid of that. now my problem is it wont start... i tryed adjusting it for the colder wheater by lowering the clip, which is when it quit starting, so then i raise it two notches, nothing... so i put it back to stock and nothing... i have a broken gasket between the carb and manifold and might it be latting too much air in?? oh and looking at the jets could it be possible that one really said 72??
