My 86 spree bogs on top end.

[Ipuddy]

I recently bought a 1986 Honda Spree. I bought the spree without hearing it run, but it is in really good shape and was told it was running two weeks ago. I figured it was worth a try. I paid $150.00 for it. I got it home and charged the battery which I was told was a week old. Once the battery was charged I hit the start button and nothing happened, the starter engaged and that was it. I thought I was screwed and the engine was seized. I took the side cover off and turned the starter gear with a wrench and I could move the crank but it felt like there was just a ton of compression. I took the plug out and hit the starter button again and the engine started cranking like crazy, but....... There was a ton of oil and gas that was built up in the cylinder that caused the engine to turn so hard. It was just spraying out of the cylinder. I bought a new plug and tore the carb apart and cleaned everything. Put it all back together and pushed the start button again and it fired right up. It runs pretty good, but I am having a hard time with the idol and on top end it seems like it is really loading up and will not open up like I think it should. I am new to this forum but have been reading some of the things posted. You guys seem to know your s*** about these scooter so I am looking to you all for help. Thanks

Idle too high ?....Idle too low ??
Cylinder filled with fuel/oil indicates petcock has failed, allowing fuel to drain into carb when it should not. Petcock is vacuum controled and should be "OFF" when engine is not running. Also indicates that the float needle is failed...it should prevent flow into carb after reaching the proper level in the bowl. Sounds like your bike is letting gas flow all the time.

Thank you for your response. It is hard to get any real good consistent idol out of it. When I first start it the idol is just fine but after I buzz around on it doesn't idol at all. The petcock sound like a really good place to start and it makes a lot of since what you are saying, but if the petcock were bad and flowing all the time wouldn't I have the same problem I did when I bought the bike were the starter would not have the power to turn the bike over because there is soo much fuel in it? Once again think you for responding.
