I think you should have someone do the repair for you

hi guys what i did with my cylinder head is i did argon welding and with the tap of 9.7mm i did make the thread and now its work what u say this will work or not???

Only problem with welding is it takes a very skilled hand to not put too much heat into the cylinder. Also you would need access to a milling machine to clean up the gasket surface. Adding too much heat can alter the heat treatment of the cylinder or warp it. I would like to see a pic of the finished product as fixing with weld is quite ambitious.

You would need a special peak reading volt meter to see the output voltage from the ignition module to the spark plug. The current is very low but voltage very high. You can check the current consumption on the primary side of the ignition very easily with a regular VOM connected in series in the positive lead coming from the battery.

Without a peak reading volt meter, there is still a way to test that the ignition module will output a sufficient amount of voltage to operate under load. It is best to use one of the little testers mentioned above but it alone with only a spark plug in the plug cap will give you very little information on the strength of the coils in the module.


To test the strengh of the coils and output potential of the module, poor man style:

1. Remove the spark plug from the spark plug cap.
2. Connect the ignition to the power supply source that is in your plane.
3. If you have one, plug the Rcexl ignition tester into the sensor lead on the ignition module.
4. Put a small diameter screw driver into the spark plug cap and make contact with the small spring in the bottom of the cap, hold the (plastic) handle of the screw driver so the shaft is centered in the opening of the plug cap.
5. Turn on the ignition power supply, turn the ignition tester up to about 3K RPM, the spark should be consistently arcing ~1/4" from the screw driver shaft to the spark plug cap metal housing.
6. If it doesn't, pull the screwdriver out and look for arcing in the bottom of the plug cap that would indicate a hole in the silicone boot. If there's arcing in the bottom of the plug cap, replace the spark plug cap.

I was waiting for the part where you were going to tell him to insert the tip of his tongue.
