I pulled a very ratty looking PT from the scrap bin at the tip yesterday, no front axle, blades virtually non existant , rear wheels trashed. This mower was obviously being used till the poor thing just fell apart. Got it home and thought I had wasted my time, pull start wouldn't move but blade carrier turned. Pulled the carby off and signs of water inside so I expected to see rust/water inside when I replaced the pull start. Put my test carby on and a new plug cap and it started second pull and runs like a good PT should. I also picked up a F/C last night for $10 and that had obviously been sitting under a tree for a long time. My wife asked me why I had paid $10 for that thing. Pull start was broken put the test carby on it and a plug cap, drill start it and it fired straight up. I am constantly amazed at the number of these mowers I pick up in terrible condition that have motors on them that are in excellent working condition
