I would think about investing in a carb re-build kit.

check the kill switch and side stand interlocks betcha one is sticking

Check the fuses. Is the kill switch on or shorting out? Disconnect it and then check for spark. Sidestand/centerstand should be up, Got a good battery?

I am unfamiliar with your Keeway and just trying to help. Don't give me a bad rating if I miss the mark on this one. Thanks.

No guarantees but try this. Pull the slide from the throat of the carb. Now move the clip on the jet needle down one notch. This will richen the low end mix. Two notches may be needed but do one notch at the start.
