    Last mow of the season I yanked the pull string out of it, let it sit over winter, now I've replaced the pull string, spark plug, and oil and I can't even get a putter out of the engine. Does anyone have any ideas, or is it just due to the cold weather we still have around?

    Did you overfill the engine? That will cause it to not crank.

    Also is the bail working on it?

    You did not say if it had fire to the plug. It is possible that the coil and or flywheel has been contaminated with rust and needs to be cleaned. Or it may not be getting fuel to the engine... Lots of small things need to checked , these can be done very quickly. good luck :cool2:

    At first I just changed out the new starter rope. Then when I couldn't get it to start I replaced the spark plug and oil. It had oil in it through the winter. Right before winter came it would start first pull.

    Try squirting a little WD40 or carb cleaner in the carb intake, if it starts and dies, the carb is gummed up and will need to be cleaned.
