Hey everyone,
It's been a while since I've posted. I got a deal on a Coleman ct200u mini bike at Sams Club last Saturday for 400 bucks plus tax. Problem is I'm getting a lot of black smoke coming off the exhaust and on to the mud guard which means the carb is running rich? New to carb engines/small engines as it is. I'm also getting vibration through the handlebars at idle and tightened everything down. Almost makes it painful to sit at idle. I called Coleman and they said I'd have to bring it to one of their shops, but I drive a two door solara and this things too big! Moving out to the jersey countryside (yes they exist) really has me yearning for a pick up (or trailer hitch).
I took it out for an italian tune up, but it didn't make the problem go away.. maybe the plug is fouled?
FYI carburetor is not adjustable and the idle screw doesn't exist, can't back out the jets either (thanks EPA) they also welded the throttle adjustment screw since people were taking them out to raise the rpms on these things.
It's a fun little bike with a honda gx200 clone Hisun engine. running rotella 10W40 in it.
Attached a picture too!
