Spree Bogging Down and Over-revving
Posted: Thu Jun 08, 2017 8:28 pm
Hello,
I've been trying to get this one Spree running for over a year now. I think I finally have most of the issues sorted out, but there is one last one that I can't seem to get.
It has a hard time starting (whether cold or warm) and I've been using a drill with a socket on the starter sprocket to start it so I don't kill my battery or wear out the kick start until I can get it to run reliably. When I do get it to start, I try tuning the carb as stated in the manual (find the highest idle speed with the mixture screw when warm and then adjust the throttle stop screw til the back wheel stops spinning). The mixture screw only seems to affect idle for about the first 0.5-0.75 of a turn (which is almost killing it) and then after that no matter how far I turn out the screw, the idle seems to stay the same.
I can get it to idle okay it seems, but when I rev it up under no load, it almost seems like the throttle is sticking because it keeps running at the RPM even after the throttle is released (the throttle is NOT sticking through as I confirm it goes back to the idle position). When I sit on the moped and very gently (pretty much no force at all) hold it in place and give it gas, it bogs down and if I don't release the throttle right away it will die. I can get it going by pushing with my feet and it still seems to struggle until it gets to a certain RPM and then it picks up fine. Again, if I let off the throttle at this point it seems like I set cruise because the Spree will not decrease in speed unless I press the brakes.
I've tried everything that I can think of and looked through the entire manual multiple times and haven't been able to figure out what the deal is. Any help or suggestions would be awesome. I had another Spree that didn't run and was able to fix that one up in under a week (sadly that's the one I sold though).
Thank you!
