Help!.....Stumped by no spark.

[Simplicity725 15]

Hello all,

I am at a total loss at the moment! The 8hp briggs in my '63 Simplicity lost spark awhile back and I am just recently getting around to fixing it...or so I thought. I installed a new coil/magneto and a new set of breaker points and condenser. Nothing. I tested the magneto with an ohm meter and it reads about 2,700 ohms which is fine based on what I could find on the internet (B&S said between 2,000-5,000 ohms). Is there a way to test the condenser? Any tips would be immensely appreciated!

Disconnect the ground wire from ignition switch and then try it. Sounds more like grounding problem for openers.

Be sure plug wire has no breaks or mouse chew.As Bob stated,sounds like a ground issue. Can also pull the black kill wire from coil and see if that does anything.

Depending on the engine, there may be a grounding (kill) wire from the coil to the carburetor that will kill the engine when throttle returned past idle. Have seen mouse chew expose it under the cover, allowing it to ground on the engine
