Gasket-intake V103000400

1. Used replacement parts videos as a check-list go-by. Had previously replaced the carburetor and gaskets but blower would not start. Confirmed procedure to ensure there was a spark. Three things required for an engine to run: fuel, air and spark. Air was no problem - had air filter off to fully allow air into cylinder. Fuel was no ... Read more t a problem - unit either hydro-lock (too much fuel when pulling start cord because engine would not start) or fuel visibly in engine when plug out and pulled on start cord. Followed procedure to check spark. Spark was present.
2. Reviewed ereplacement parts video for other sources of failure to start. Found video re: flywheel and flywheel key. Removed flywheel to check for flywheel key and determined it had been sheared off. (The key sets the timing of the spark, so that magneto fires when piston at appropriate degree from top dead center). If timing is off, engine will not run even with air, fuel and spark.
3. Replaced flywheel with replacement unit from ereplacement parts. Also ordered new gaskets (eventually only used one) and new air filter although had replaced those when replaced carburetor.
4. In retrospect, probably did not need to replace carburetor since the failure to run now appears to have been a timing issue.
That said,
1. Disconnect spark wire. Remove spark plug (requires spark plug socket or appropriate size wrench).
2. Remove screws holding engine cover and fan covers.
3. Remove blow tubes.
4. Remove engine cover and fan cover.
5. Remove throttle rod.
6. ereplacement parts video says to stuff cord into cylinder to prevent piston movement. I jury-rigged a cord from string -- not sure it was effective but had no issues.
7. Remove flywheel. Confirm flywheel key sheared off. I though the key was a separate piece but it is a small tab on the inside of the flywheel that fits into a slot on the engine crankshaft. Replace with new flywheel.
8. Reassemble. Note that at the throttle rod and ground wire for run/stop switch fit inside engine cover as reassembling.
9. Replace spark plug. Wipe spark plug anti-seize on threads of plug before installing. Hand tighten and then slightly more torque to seat.
10. Follow starting procedure. May have to pull start rope numerous times (more than you think necessary!). In my case, it took a number of pulls to get the engine to start. (Actually stopped working on unit for a while to \"walk-thru\" check-list of repairs to think about why this unit won\'t start. Concluded it needed more effort). Used shorter pulls more quickly, engine caught, then stopped several times, but finally turned over and ran.
11. Enjoy having fixed a blower - saving purchase price of new unit and saving a good piece of equipment.
