20 Most Recent 2008 Keeway Matrix 150 Questions & Answers

Hi. Keeway scooters usually do not have kickstand switch. Check if there is one just in case. If there is kickstand switch bypass it. Check fuel switch, fuel filter and hose. Try starting with no fuel cap. Check and replace spark plug. Check carburetor oil and oil tube. Check carburetor mixture and idle settings. The carburetor needle may be clogged in some case the carb must be disassembled to clean part or regulate needle height. Unscrew the discharging fuel screw for the carburetor and check if there is fuel flow. If fuel flows test the ignition wiring , CDI and coils in the magneto. I do not have the service manual for this scooter. Here a service manual for a Keeway ARN 150, similar to Flash Check the service manual tests and diagnostics are the same and wiring diagram is similar. Regards. Ginko

The thing with two strokes is that they smoke a bit under normal operation, and they smoke like mad if they haven't really been run for a period of time, I would advise you to run it for a while and see if that helps.

You should not need to adjust the mixture settings at all.


Hope this helps

you could re-jet the carb or put a larger one on but that would mean making your own manifold, and you can open up the pipe to make it less restrictive.
