SOURCE: the cultivator is getting gas, the plug looks new but no fire

Check Compression, if you dont have a gage put your finger in spark plug hole it should blow it out.
Next check for spark,It should be a blue spark at plug.
Next put a little fuel in carb and see if it will fire.
Hope this helps. Let me know.

SOURCE: Cultivator won't start.

After sitting for that long the carburetor will gum up and not let gas through. Buy a carburetor repair kit and replace the diaphram and gaskets. Be sure to make a sketch of where the fuel lines are routed to. It's easy to forget where they went and a headache to try to figure out. If it has a primer button I would replace that also.

SOURCE: 31cc yard machine garden cultivator.

Only 3 possibilities for no spark. First, are you using an inline spark tester to determine there is no spark? If so, here's your possibilities.
1. The on/off switch is shorted out.
2. There is a short in the wire(s) from the switch to the ignition module.
3. The module is faulty.
Dissassemble the engine cover far enough to access the module. There is a small wire that leads to a spade connector on the module. Disconnect this wire. Retest for spark. If you still have no spark, the module is faulty and must be replaced. If you now have spark, then the module is good, so back track the wires to the switch to determine if the wires are pinch or chaffed, or if the switch is stuck in the off position.

If you are not testing for spark with an inline tester, please, please go to Walmart or Pepboys or Autozone or NAPA or Sears and spend $7 to $10 on the will save you alot of trouble.

Good luck.

Bolens cultivator model BL425 engine will not start

I would make sure that you have the proper gas/oil ratio mixed first. If that is ok then I would have the filter changed. If that doesn't solve the problem then you should take it in to have the carburetor serviced.
