86' Spree dies past half throttle...

[Spreedemon]

Just got the Spree a few weeks ago and it runs ok... usually starts on the first try. I'm loving it...other than the fact that it wants to die if I give it too much gas while riding.
I've cleaned the carb, air filter, checked hoses and kicked it a few times... but nothing seemed to help. I can get it up to about 20mph on a flat, but any incline (hill) gives me grief and I slow to a walk. If I try to give it more than 1/2 throttle it floods out or something and dies if I don't back off the gas. I could really use some advice now... I've been reading the other posts here and noticed that others have the same problem. Is this just a Spree Thing that happens?
So, what else can I do to "fix" this problem?

I would suspect a fuel delivery issue but flooding is not it. If anything it is too lean. Is the air filter box, hose, etc. in place and sealed up as designed, with an good air filter in place? If not, there is your problem.

[Spreedemon]

Yes, as far as I can tell the air filter box and hose are attached correctly... and I re-oiled the filter last week... it was pretty clean already but thought it wouldn't hurt to do it. So too lean meaning too much air or too little? I'm kinda new to the Spree stuff/small engines.

Lean or rich always refers the amount of fuel. So lean means not enough fuel and too much air. This can be caused by a vacuum (air) leak or the lack of fuel.

Too much air;

Carb isolator installed back wards or upside down or "o"ring on carb or isolator/space torn or missing. Bad gasket at intake/reed block/engine block connection. Loose or leaking air cleaner or connection to the carb.

To little fuel; (and I think this is your issue) partially plugged filter in gas tank, partially obstructed petcock or fuel line (new fuel lines are a good idea on these old scooters (I prefer clear fuel and vacuum lines). Low float level in the carb, partially plugged main jet or emulsion tube above the jet.

Thanks for the tips...and the lesson I'll check them out and hope it's something easy Think I'll replace the hoses anyway... I don't know how long they've been on there, but I'm sure it's been over 5 years. *, they might be Stock for all I know

I don't care what anyone else says about you, Bear... you are knowledgeable and patient with ppl who don't know *. It was the Hose from the air filter... it was not getting a good seal. Got it sealed and was able to hit 30-35 at full throttle Thanks for your help - I know it was a basic thing, but you made me look twice at it and that's when I saw it...so... Thanks
