Customer Question

I have a craftsman pressure washer with a 7.75 up Briggs and Stratton engine. I have no fire. I have tested everything there is. The kill switch is good, the coil is good, and the spark plug is good. What else is there? I'm really stumped here. Does this engine have internal points?

What method are you using to check for spark to your spark plug?

Customer: replied 1 month ago.
Hello Donald, I used a multimeter to check the ohms

Thanks for this information. How long has it been, since your engine last performed to your satisfaction?

I'm not sure. Someone was throwing it away and I took it.

Do you have some carburetor cleaner in a can?

Expert:  Donald replied 1 month ago.

Remove your air filter housing, and your air filter, then spray a small burst of carburetor cleaner directly into your carburetor, to see if your engine will start up briefly.

I have tried that.

At first I thought all it was it needed was the carb cleaned and some fresh gas. I flushed the tank checked the bowl for trash and cleaned crab with cleaner. Would not crank took outspark plug checked the fire. No fire now I'm trying to trace it downbut I don't know where else to go with the trace. When the coil is good but does not fire the plug.

Have you taken the shroud / cover off your engine, to expose your ignition coil?

Customer: replied 1 month ago.
Yea
Expert:  Donald replied 1 month ago.

There is a small black wire attached to your ignition coil. This is your kill wire. Remove your kill wire, from your ignition coil, then check for spark again, using the procedure, in the link above.

Yea still no spark..
Expert:  Donald replied 1 month ago.

Is there any rust on your flywheel, or on the legs of your ignition coil?

Customer: replied 1 month ago.
There was but I sanded it off
Expert:  Donald replied 1 month ago.

If there is no rust present, and you are not getting a spark, after you removed the kill wire from your ignition coil, is an indication that your ignition coil is bad, and will need to be replaced.

Expert:  Donald replied 1 month ago.

Without your kill wire attached, there is nothing to prevent your ignition coil from producing a spark.

Customer: replied 1 month ago.
I tested the coil with my ohm meter and it reads that the coil is good though
Expert:  Donald replied 1 month ago.

Where did you get the ohm specs for your coil?
