Check oil level, take off the spark plug clean it and regap and or buy new one and regap. Take carburator off and clean it. Test coil and ignition switch. Clean gas tank and fuel lines. There could be a lot of other things to check. It could be a safety switch, dirty cables,bad battery or bad wiring. It could just be a loose wire that's not grounded.
Most of the time on older engines, the carb needs to be rebuilt or replaced. Dont panic rebuilding is cheap an easy. The ports get clogged up sitting an varnish up. Try to clean out all orifices with small pieces of wire from steel or brass brush. Use carb cleaner to clean replace all gaskets an parts with kit. Dont forget to check fuel hose in tank they go bad often an should be replaced when carb work is done. Fresh gas an it should work
gap needs to be 10 thousands of a inch done with a brass feeler gauge ..mag/flywheel has a spot with a magnetic field if you look you can see it it should make a 1/2 wrench stick to it if not replace mag/flywheel ..check key way also
A weak spark can be attributed to a number of issue: 1. Wire from the magnetto to the spark plug is saturated with oil (clean well with degreaser) 2. Spark plug cap deteriorated. (most are not easily replaceable) 3. Spark plug fouled (insure you are using new) 4. Significant build up of rust on the flywheel (lightly sand rust off) 5. Bad Magnetto or CDI (especially if it has gotten wet or is cracked.) Note: (Cost typically prohibitive for replacement). 6. Spark plug gap significantly out of specs. (Regap to specs, retry)
If you are certain you have a weak spark, these are typical causes. Often, more likely problem is carburation, fuel filter and/or fuel lines - which are much easier and less expensive fixes! Hope for the fuel lines being cracked...Good luck :)
Make sure you have a new air filter, new spark plug and fresh fuel. Then get a can of starter fluid and a helper. Squirt some starter fluid at the air intake and start it. Have your helper continue to squirt the starter fluid to keep it going as this will clean out the entire combustion chamber. J.
this is not a problem
you need to remove all the fuel
and remove your spark plug add new fuel and with the spark plug out pull it over many times to purge the system now install a new spark plug and you will be fine
