Dead Voodoo Doll Posted July 8, 2013 Report Share Posted July 8, 2013 Anyone know anything about fixing 2-cycle engines? My lawnmower has been a serious case of frustration this summer. It's a push mower (Lawn Boy, Gold Series Self Propelled rear-wheel drive), close to 15 years old. At the beginning of the summer it wouldn't start at all. So far I've: Suctioned out the fuel tank Replaced the carburetor (basically completely rebuilt) Cleaned the air filter Cleaned the spark plug Now it starts, but it only has one throttle speed and if I kick on the automatic drive it cuts off. What I listed above is the limit of my knowledge but I guess I can tinker with it some more. I've been cutting my grass by doing the following when I hear it is about to cut off: I will yank back on it so it's not cutting anything and the blade will pick up speed again and keep going. If the speed is set to slow I'll slowly move the throttle to fast and vice versa. It's freaking annoying. Any suggestions?

The Forsaken Posted July 8, 2013 Report Share Posted July 8, 2013 Might be a stupid question, but how tall is the grass you're trying to cut? Push mowers can get bogged down pretty easy on tall grass. Link to comment Share on other sites More sharing options...

Kyzarius Posted July 8, 2013 Report Share Posted July 8, 2013 did you leave it a long time with gas in it? I have found if you store it with gas in the lines, this can erode the plastic hoses and lead to cracking. This can allow air in the line, or cause it to lose pressure when throttling, thus dieing when you give it gas. Link to comment Share on other sites More sharing options...

I did leave a little bit in there over the winter thinking it would be fine and nope, it wouldn't even start this spring. I eventually siphoned out all the old gas but if it broke down and cruded up the lines that wouldn't have helped. The carburetor was really gummed up.
