Small Engines (Lawn Mowers, etc.): push lawn mower, grass catcher, push mower

Question
I have Techumsen 6.5 push mower that ran good for an hour or so but when I shut it off to empty the grass catcher it would not start nor has been able to start since (has gas in float). Also, it has always pulled  extremly hard on the up stroke.

Answer
Hi Jason,

You will need to determine if the problem is a lack of spark or a lack of fuel flow.  Right after it quits, remove the spark plug, reconnect the wire and lay it against the engine head.  Pull the engine over and watch for spark at the plug's electrode.

If good, then try to start while squirting fuel or starting fluid into the carb intake.  If it starts, then the carb most likely has dirt, debris, gummed fuel or water inside.  You will need to remove the carb, disassemble it, clean all the small internal openings and blow it out with compressed air.

Let me know how you make out.
