Dead '86 Spree - no suction

Lamb · Post by **Lamb** » Thu Feb 05, 2009 5:00 pm

Right, so this is my first scooter, I bought it from a shady guy, and it had no torque originally. I figured it would be a simple enough repair, and took it in. After buying it, I bought a gas cap for it, cleaned the carb, and gave it an air element-but I'm not sure about the cable assembly, and I'm pretty sure the vacuum hose isn't getting any 'suck'. It would start up fine, but couldn't accelerate for crap, then it sat around for a few weeks while I got all the parts to put it back together, and now it won't kick.

does this assembly look right to you?

When I first got it the black/red cables were the reverse of what they are now. If you suck on (what I think) is the black vacuum cable, gasoline flows from the red one; but if you pull the vaccum cable from the gas tank, cap it with your finger and hit the kick-start, there's no suction at all. Thanks in advance for any help, feel free to ask questions if I've left anything out.

edit: Spree doesn't like the cold, but the throttle is now stuck on full-see newer post.

If it ran recently and there's no reason to believe there's a gaping hole in the piston or a huge canyon in the cylinder wall, I suggest you remove the carb and manifold. Check the reed valves. If they don't lay flat against the block, that would explain a lack of vacuum. Anyway I suspect there's not a lot of vacuum there unless the engine's running. Not sure you could feel it with your fingers, but I've never tested.

I agree about the reeds. If one or both is stuck open, nothing will happen. Also make sure to check the gaskets.

Well, I didn't actually get around to trying any of the suggestions given, on account of my laziness, though I do appreciate them. A few days after I made this thread, I gave 'er a kick, and she purred. Apparently Sprees don't like starting in sub-zero weather, but the 60 degrees today was OK ;P

New problem- the throttle's stuck at full, it can't be adjusted. If I turn it back, it stays back, if I turn it forward, it stays forward; but, it's always gunning it at full. Solutions?

You have the carb slide in wrong, there is a nub in the carb that aligns with a slot in the slide.
