Oh man, another good one!!. Thanks T Mike.

That first way is how my dad check spark that way he would grab the spark plug on the car when it was running great videos

Best tutorial on the tube, awesome,

[@edgarlowe6476]

Hey T-Mike, could you do a video on testing compression. What to look for. What’s good what is bad. When to think about honing and new rings. I have been looking for some knowledge on these 2 cycle motor and it’s like it’s the best kept secret. No one wants to give it up. Lol

[@travisestes6217]

Hey T Mike! I've got a 1966 Johnson 6 hp. On both plugs I get spark across the inline light test like #3. I've cleaned points (1 ohm across) and have 6-8,000ohm from coil/spark plug boot wire to ground. I dribbling a little fuel in each cylinder just hoping for a pop with no luck. 80/75 psi compression. Any thoughts?

[@michaeljsimon]

Try switching wires - might be reversed.

[@travisestes6217]

@@michaeljsimon Thanks for the reply! I've got the shorter one on top and longer on bottom as they were when I got the motor. I can't see a spark when I try grounding the plug(s) by hand/boot of plug wire either. I will say my tiller handle/gear seems pretty bound up. Is there a kill switch mechanism that would allow an inline tester to show spark but not actually allow spark to be made?

[@michaeljsimon]

@@travisestes6217 I don’t trust the in-line testers - prefer the Sierra gap tester.

[@gjpgonzo2189]

ok I got the 1/4" spark tester. I have awesome spark on the top, but intermittent spark on the bottom. I have checked the coil windings .9oms, and continuity to the boot, cleaned the points, checked timing, swapped out condenser, but still intermittent spark out of the bottom....am I missing anything?
