hi bruce
i have a honda gx390 with weak spark could you tell me what the resistance of the coil should be
thanks

mattauto,

As this is electronic coil I don't have the resistance settings but if you click this link to contact Honda I am sure they will be able to supply you with the information.

The weak spark issue might be because of the air gap between the flywheel and legs of the coil. To set the gap just use a normal bussiness card between the coil legs and th flywheel magnets.

I have a GX140 that had the same problem, I checked the timing and it was out a little, and I used a feeler gauge to set the distance between the flywheel and the coil legs (use a light amount of emery paper to clean up the contacts for a better spark).
