so if it is noticeably easer to pull the start cord the compression is toast engine is bricked this can be from valves, valve springs or cylinders being hosed. The first thing I would do is remove the spark plug & spray some starting fluid or carb cleaner down the hole if it starts up then you now know to go after the carburetor &/or air filter. If that gets you nothing & your getting a good compression reading (witch you shouldn't be getting) & hearing a "puff" then it sounds like your compression release is stuck. Most of the time if a little engine gets punched wide open for to long the compression release gets out of whack or broke. If your engine if a vertical drive shaft I would just keep an eye out for a fee lawn mower with a similar engine. If its horizontal drive shaft its worth a fix. If you can ID the manufacturer of the engine you may be able to get some help through there web site on how to fix it.

> it like puffs out air after each pull
.  Since you don't mention it doing any puffing before, that, in combination with "held down the governor rod too long" sounds like you broke a valve. I suspect you do not have much compression, but hard to tell from here. If it puffs out the carb, the intake valve is broken. Puffing out the exhaust is normal.
.  If you really do have compression, I'd start with the basics:
  • Make sure the spark plug is in good shape and that you are getting a good spark.
  • While you have the spark plug out, make sure you are getting proper compression.
  • Drain the gas tank and add fresh fuel.
  • Check/clean/replace any filters between the fuel tank and carb.
  • Verify you are getting fuel through the carb (should be able to smell fuel coming out exhaust port).


Valve spring.

If your friend "buggered" it - oblige them to have it mended.
