Murray Push mower with B&S 625e Series Engine
Engine Model Number - 122N02 6377 F4
This mower was bought brand new last June. It worked fine all summer, unfortunately I did not winterize it properly.
It had some trouble getting started a few weeks ago, but it worked well enough to cut the grass. It would take a few pulls to start, then if I turned it off for any reason, it took about 20 pulls to start again. Pulled it out to mow again this weekend, had the same experience for about 3/4 of the lawn before it stopped dead and suddenly would only restart long enough to belch out white smoke.
I replaced the air filter, cleaned the carburetor bowl, refilled it with fresh 93 octane fuel, , cleaned the spark plug (I haven't been able to find any of the correct size in my area, apparently its a popular size and everyone has bought them up, so I can't replace it yet)
About every 20-30 pulls, it will turn over and start for a few seconds and belch out white smoke and backfire. If i take the spark plug out after that it has gas on it. I can clean it off and get it to start back up for the same scenario after 20-30 pulls.
I have no ideas on this, anyone else have any?
