Coleman CT 200u EX 2nd Test Ride
- Thread starter second childhood
- Start date
Any chance the clutch spring is weak?, biggest issue I've encountered on these clone engines is the fuel tank outlet filter not allowing enough fuel, or any fuel to flow out and down to the carb., The NOS 200u I just picked up the fuel wouldn't even flow out of the outlet, a little frustrating but I keep new replacements on hand, I had it up and running in no time....

That's the best starting point. I'm still trying to figure out why so many people have this issue. The throttle assembly design for these clone engines have been used for a lot of years now. Even a pre Predator Harbor Freight engine has a nearly identical throttle assembly as what you see on the Hisun engine.

If the black lever is not touching the idle screw then on top of the metal throttle assembly there is a bolt that holds the throttle arm on. If that bolt is too tight it will not let the entire throttle linkage return to idle. Loosen it just enough to where you get full movement.
Charles posted the parts link above, go to: CT200U-EX - Regulating Control System to see the bolt I am referencing at the very top of the picture...
Also make sure your throttle return spring is not binding. I had to cut a couple links off of mine.

Hey Thanks for all the input from everyone, but here is a update and I hope it isn't too early. I put a Block in front of the back wheel and started the bike and it stayed against the block of wood, so i reached in with a long drill bit and pushed the throttle lever against the idle screw and the bike shut down. So then I readjusted the idle stop and got it to keep running but to idle down so the clutch wouldn't start to engage. To make a long story short I stretched that little spring that MJL talked about and now the bike is idling down just fine on it's own. Time will tell all tales. THANKS Everybody!
I always thought it was odd that the tag on the Hisun gas tank says to run 90 octane or higher. You would think that an engine that has around an 8.5/1 compression ratio wouldn't need anything more than 87.
The guy in this video found out while testing his carb mod his exhaust temps are 40 degrees hotter using 92 octane. Since when did an unmodified clone engine require anything higher than 87 octane?
