Thanks. I think you are right. I got the lawn mower without a user manual. I just downloaded a copy from the internet and see that it says I should charge the battery once every 25 mow. It didn't occur to me I need to do that because my snowblower is the opposite. It doesn't have a battery and only need to be plugged in when I fire it up. I am glad it's something so simple.

"Check your valve clearances which is easy to do on your engine. They may be too wide defeating the compression release" Compression release seems to be working based on the feel of the pull force on the rewind starter. Your right, easy to check though. I should probably get the specs on the starter motor and test it too.

OK, try this just to make sure that something is not obstructing the fuel inlet (needle and seat passage). Connect a short length of fuel hose to the carb fuel inlet nipple. Now try to blow through the hose using your mouth/lungs. With the carb top removed, you should be able to hear the air coming in through the needle/seat. If you can't hear air coming in like that, something is obstructing the fuel inlet or needle/seat area. If you can hear air entering the carb inlet, then you have either a defective fuel pump, or something is wrong with the marine tank/fuel lines. While you have the top off the carb, fill the bowl with gasoline before putting the top back on. When the top is back on, try to start it. If everything is satisfactory with the carb itself, you should get about 30 to 40 seconds run off the fuel in the bowl (your results may vary).
