Doodlebug won't stay running

I bought a baja doodlebug about a month ago and haven't had any problems until yesterday. It suddenly got very hard to start and when it does start, it will only idle for about 5 seconds and then shuts off. Any attempt to rev it during that 5 seconds results in it immediately shutting off. Since I know very little about small engine repair, I was wondering if anyone had any suggestions?

swap in a clone.

like Jim said, start by cleaning out the carb. it doesn't take much to clog a jet.

Lightbulb Can of carb cleaner good as gold!

Get a can of carb cleaner with an extension tube, take out the carb adjustment screws and spray cleaner liberally inside until you see it coming out the inside of
the carb.

This usually does the trick 4 me.

Also, if you have a fuel line, cut and install an inline filter. This will help with future carb problems.

Good luck and happy puttering!!!

i've had a bunch of random crap show up in my filter. i'm glad it didn't make it into the carb/engine.

Oh Yea, it's surprising the amount of crud that ends up in your tank, all it takes is one tiny piece to end up in the carb and

The most important things in my shop are my can of carb cleaner and a box of filters, they've both saved me a lot of frustration.

One reason I dislike the carb/tank combos by B&S, no way to install a filter.

Ours were doing the same thing. I tried everything and finally raised the idle speed just to the point that the bikes almost want to move on their own. That fixed them.
