Spark test-Easy to verify.
Somewhat of a guru Slavensracing using a simplified spark test.

Bike braking down

A trick I use to do is tape my timing light to the bars pointing back at me and ride the bike. If the timing light cut out you new that it was an ignition problem. If it's dying and the timing light is still blinking and you have a new plug, then you can start chasing fuel.

Seafoam in the gas helped my bike run a lot better and smoother - then I cleaned the injector manually and changed the fuel filter and all was good.

Hi!! How i set my float hight properly ??? I have a pwk 38
Thx !!

The float needs to be parallel with the carbi. If not then adjust the small "tongue" that pushes the needle valve

Here a very basic video of the operation. When you check don't have the weight of the float pushing on the needle but only resting on the needle lightly. This is the reason you keep the carbi at 45 degrees.
