Does anybody know how to swap the polarity on the magnet? Startech? You seem to have some history of this. Peter

I can confirm that the magnet on my engine has the S pole on the left using a compass. Looking at the diagram flipping the coil will not help. It will not change the direction of charge. I think i need a new magnet (flywheel) Peter

Look what I found.

It's a Tecumseh Small Engine Model LEV120. The Recoil starter pulls in a CW direction. What can i say Hammerman. I found some manuals but none actually say what the direction of rotation is. CW from the flywheel seems to be the norm from what i've been reading. Peter

OK. I elongated the holes and got the new coil to fit upside-down. Guess what... the spark is still only CCW. Peter PS the engine is on a campbell hausfeld PW174901LE pressure washer. Not sure the actual engine.

Great response. Who knew how complicated these things are. I'm an electronics engineer but had no idea i would need that on a small engine. As i said before the coil only fits on one way due to offset screws. I will look at flipping it if i can. Rainy day so it might be time.

I was under the impression that the coil was just a coil with low and high voltage coils. Hall effect transistors are low voltage and are triggered by magnetic field. do you have a typical circuit diagram? If the Magnet has flipped is it possible to replace it? I can't see any being sold unless...

Hello Bert. The holes are not equally spaced and only go on one way. Old and new.

Hello, I have a pressure washer with what I think is a Tecumseh engine. Failed to start and there was no spark. Ordered a new coil as they ae pretty cheap these days and i didn't want to mess about. Stll no spark. This is a simple engine. No points or condenser, just a cut off wire. With the...
