Doesn't the same effect on the coil happen when you run a 2 cylinder on only one plug wire. As in removing one plug wire, starting it, then repeating the process with the other side?
The electricity being created by the coil with the disconnected plug wire has to go somewhere also. Right?
Any tips on removing a plug wire while the engine is running.
I know that sounds like a rookie question. But the first and only time I've done it (decades ago), I got the fire knocked out of me, and never tried it again.
I didn't mess with that part of the carb. As I didn't have replacement gaskets. And mainly because the rest of the carb was just too clean to think there was any need to get into that far.
Yes, sprayed carb cleaner through every hole, keeping an eye on the stream that comes out the other end. Especially to two ports that come out into the venturi. Ran the guitar strings and probes through the holes and the jets. Replaced one intake mounting gasket. It was very clean.
I got the new tester in (after I returned it). When I get back over there, I'll see what the spark looks like. Customer says it's funning fine now. But I'm thinking she just can't hear what I hear.
True that. But what I'm supposed to be looking at is gaps between sparks, instead of a constant blinking, correct? Even with the junk ones like I have, these gaps are visible.
I did notice some gaps in the spark. But they didn't coincide with the backfiring. As in many times there was several...
With the spark testers I have, I see no formidable differences between either side.
Note: They're not adjustable air gap spark testers. But I they do show when exactly the voltage comes through. Both sides glow bright.
