Can you replace the whole spark plug wire on the coil on 8hp Tecumseh without changing the coil

are you sure the ground is releasing on the brake

spark plug wires are attatched to the coil. to replace the whole plug wire you need to change your coil. The boot can be replaced by itself but only if the wire is good

The coil needs to be just close enough not to rub. Wrap a piece of hard copper wire on the threads of the plug and ground the other end to the engine. Pull the handle and watch for spark.

Check the gap between the coil and the flywheel. You can fold a dollar bill over a few times (3 or 4 layers thick) , place it against the flywheel , **** the coil up to it , and then tighten down the coil. This will give you a good clearance between the coil and flywheel and promote good spark.

Essentially I am suggesting you use the folded dollar bill to set the coil to flywheel distance/gap.

If it still doesn't work, I am at a loss. Is this a multi cylinder engine ? If so , does it have points or electronic ignition ?

Try checking the plug end cap with an ohm meter for an "open line" reading.
I changed the coil on my no spark Honda G300 and reused the original resistor cap.
However I discovered it was the resistor cap that was at fault.
To fix I used a rubber boot and metal end cap from a car plug wire but new replacement caps are readily available.
Now have a strong spark.

If plug is dry than you are not getting fuel to the plug something is plugged up in the carb clean it thoroughly and make your coil gap is correct. But I would lean more towards the fuel not reaching the plug.

well you should really cheek your spark to see if you are getting spark by using a screw driver in the spark plug agents the metal and see if their is an arc from the points

There is a shut down wire, This wire is grounded some where along the route. Look at the coil for this wire, it shorts the coil to ground so no spark can get out to the plug.

check condition of the magneto,located under the flywheel
