@@bogdanmarcu6915 make sure you check the resistance of your multimeter. If putting your 2 leads together give you resistance of 0.5ohms you would have to subtract that from your reading. Just FYI
@@autotech4103 My mistake! I have just redone the measurement as I had a doubt whether I have measured it correctly. leads resistance in my case is 0.2ohms; primary resistance is indeed read shows 1.4 -0.2 =1.2 ohm-> just outside tolerance field. Secondary is at 6.3 Kohm so 6300 ohm - way too much. I have shortened the spark plug lead hoping the issue is coming from an imperfect connection between lead and pipe but had no success. even measurement directly on line (without pipe) shows 6000+ ohm. so its clear now, I need a new coil. Thanks a lot!

Can't you use business card about same thickness , easier to gap. Both sides at same time
It has a 0.016” tolerance so yes. It isn’t very picky
Just use a longer feeler gaug under both contacts
I will try that next time….
Hey friend, my Honda GX390 starts and runs good & then starts surging & dies. Plug is white. Any ideas.
Is it quitting after it gets hot? Is the engine oil high enough? It has an oil level shutoff
My motor kicks back any idea why? Like when i try to turn it on the rope pull backs real hard is a honda gx270

Readjust your valve clearance. You have compression building at improper times.
do you know what should be the primary and secondary resistance for GX390Coil? thank you!
Primary Resistance, 0.8 - 1.0 ohm
Secondary Resistance, 5.9 - 7.1 ohm
Stole this info from

@@autotech4103 mine are: primary 1.4 and secondari 6.3. Would be a reason for no spark? it's time for a new one? Thanks a lot!
