Hummer 250 4 stroke Overheating !!

[Sinatra52]

Hi can anyone help with an overheating Hummer 4 stroke??
My bike is only a month old and in addition to the kick start dropping off on day one I now have a real problem. If the bike is started and run for approx 2 mins the exhaust pipe glows bright orange. I'm guessing this is a timing issue but I really don't know. My supplier doesn't speak much English and I can't find a manual anywhere, is there anyone who could offer any help with this problem. Many thanks Tim.

it is running incredibly lean.

You need to lower the E clip in the carby

Thanks Sidney I'm along time out of the game would you be good enough to expand on `Lower the E clip' Sorry to be so thick ! Cheers Tim

Another Thought !

How similar to the old Honda CG air cooled 4 strokes is the Hummer. The engine mouldings look very similar, I'm thinking would the Honda workshop manuals be any help ?

you might be on the money with the manual. lowering the e clip refers to the needle jet in the carby slide
