Throttle problems + stalling

Post by Steezy »

Today I was driving my two week old Buddy 50 to run some errands. I had two problems:

1. Occasionaly while sitting at a lite, old girl turned off on me.

2. Every now and then I'd turn the throttle to accelerate and nothing would happen

Whassup?

I would suspect flotsam and jetsom is blocking the jets in your carburetor. There have been a few instances of Buddy's having some foreign substance in the tank that has worked its way into the carb. It then gets sucked up outa the bowl and plugs the jets, thereby preventing gas (or at least, a full snort of gas) from getting from the carb to the intake valve. Acts just like you described.

At least, that's the first place to look...

To be honest, I'd have to look. I have a 125 and it is quite different. That being said, though, the engine layout is not that different. I would suspect you'd need to pull the under-seat bucket (seat comes with it) by removing the 4 brass bolts. This will give open access to your engine compartment. If the 50 is anything like the 125 in layout, the carb will be secured to both the intake manifold and the air intake tube by a hose clamp at each end. These will need to be loosened. On the 125, you can then carefully rotate the carb upside down and remove the 3 screws holding the bowl on to access the jets. On the 50, it may not be quite that simple since you also will have an oil line to contend with. Without my being there to actually look at it, it might be in your best interest to take it to your dealer...it would be covered under the warranty.

Thanks for the help. I'll try and get over to the dealer this week.

I know ANY downtime sucks (especially when you just got one) but don't let it stress you too much. From what everyone here and my dealer has been telling me is that if you're going to experience any problems it's going to be during the break-in period and that's pretty much with all scooters. After that you should be alright :)

Hope your dealer gets you back on the road and riding smooth ASAP. Definitely let us know what the problem turned out to be (and the solution).


Take Care

Try turning your idle up a bit first. That should be just a matter of turning a screw, and would lead to at least the first of the symptoms if it is set too low.

I tried to drive her again this morning, and problem was even worse. So I'm going to have my g-d dealer pick it up tomorrow. I would be less annoyed if the Buddy weren't my first foray into motorized transportaion in more than 3 years. Now I'm back to footing it everywhere. Tomorrow will be my two week anniversary of picking it up. ANNOYING!!!!!!!

another possible simple problem could be the plug wire... i had issues with mine, but after a couple thousand miles... the seal that sits up against the cylinder was pushing the plug cap off of the plug, not getting juice to the plug... due to living in a mostly arid locale, i removed the seal, and she has run fine since...

Did you try cleaning the spark plug? 2 strokes will foul plugs with oil.

I wouldn't know where to begin doing this stuff myself. Dealer is picking it up tonite, and hopefully I'll be back on the road soon..I'll report back what the problem is. I'm also hoping this whole shebang is going to cost me less than $50 since I've only had the thing for 15 days!

That would be my guess too. Things may need a bit of adjusting as the scoot gets broken in (and later, too). Check the simple stuff first...

Where's the idle? I'm not kidding when I say I'm not at all mechanically inclined.

Check page 29 of the service manual. Can't really offer any specifics as I've got the 125...

From a previous thread on this very topic:
ericalm wrote:The skill required to do this is no more than the ability to use a screwdriver. If you're feeling adventurous, you can pop open the seat and unscrew the door at the bottom of the pet carrier. The idle adjust is the prominent screw at the top right of the opening (as indicated in photo below). Start the scoot and let it warm up a little.

The service manual says to use a tachometer, but really, I adjust this by ear and by feel... usually adjusting so that the rear tire starts to spin very slowly. I'll usually then take it for a ride and make another adjustment as needed. If someone has a better method that doesn't require buying more hardware, I'm happy to hear it!

It will probably require as little as a quarter or half a clockwise turn to increase the idle just enough.

It looks like Steezy has a 50cc Buddy which would be a little different than the 125 for idle adjustment. If I remember correctly, the idle screw on the 50 is a black knob on the side of the carburetor. Sounds like it may be more than just an idle adjustment though. I say bring it to the dealer.

Update - Heard back from the dealership and they think I just wasn't letting it warm up enough (which admittedly, I was not letting it warm up at all). Going to get Scootz today, and they aren't charging me a dime. Booya!

Steezy, are you still having the same problem? I have a 125 and it's doing the same thing, each time I turn the throttle a little bit it would choke on me. Anyone would know what the problem might be? Thanks!

Actually, the dealer called me again, and it turned out the carborator was mal-adjusted or something. So they fixed it up and it runs a LOT better.

Still free!
