I'll need a bit more information to help. When you use the kick start does it move freely every kick, stiffen every second or third kick or completely lock up and not move? On the start button does it just spin or does it cough and try to start? That engine is a '2 stroke' engine which needs a correct mix of 2 stroke oil and fuel to run correctly. If the mix is too thin the pistons dry out, overheat and seize. The issue you have could be a few things. A blown head gasket, A badly fitted spark plug, Worn piston rings or a cracked cylinder head or block. Once you have ruled out poor spark, poor air supply and poor fuel supply the most likely reason will be the piston rings. The only way to check compression accurately is with a compression tester gauge. These are not expensive and usually simple to use.

If it seems like fuel starvation it could easily be. Check the float level in your carb(s). Is the fuel valve (petcock) vacuum actuated? If it is, this system may have malfunctioned. Either way, with float bowl(s) off gently push the float up and let it drop down. You should get gas flow when the float is down and it should stop when it's up (don't push too hard as you could put it out of adjustment). Also check the main and pilot jets to see that they're not clogged.

Gummed up air mixture jet/circuit. Needs a good clean with carb cleaner.

The lever should be tight and in the middle of it's travel

this could be a earth problem i had similiar after getting the frame painted i did not clean off the paint when i was putting the earth wires on a couple of spots ,or if you are useing the old wireing then there could be a brake in a main wire ,hope this helps

I can't find a diagram. The small potentiometer on the control board likely serves as an adjustable component to fine-tune specific parameters. Here are some possibilities: Voltage Regulation: The potentiometer might control the output voltage. By adjusting it, you can set the desired charging voltage for different battery types (e.g., 6V or 12V). Current Limit Adjustment: It could be used to set the maximum charging current. Adjusting the potentiometer allows you to limit the charging current based on the battery's capacity and condition. Sensitivity or Threshold: Some potentiometers act as sensitivity controls. For example, it might adjust the threshold at which the charger switches between charging and maintenance modes. Setting the Potentiometer: Without the specific circuit diagram or detailed information about your charger, I recommend the following general steps: Observe the Potentiometer: Identify the potentiometer on the control board. Note its position and any markings (if present). Consult the User Manual: Check the user manual or operating instructions. It might provide guidance on adjusting the potentiometer. Trial and Error: If no specific instructions are available, start with the potentiometer set to its mid-position. Gradually adjust it while monitoring the charger's behavior (e.g., charging current, voltage). Observe how the charger responds to changes in the potentiometer setting. Fine-tune it based on your specific battery type and desired charging characteristics. Remember that precise adjustments depend on the charger's design and the battery you're charging.
