"You might check the compression and spark. That little engine would sound just as good on one cylinder as both.

You might touch the cylinder head (before it heats up) for each cylinder and see if one is running colder than the other one. That would be the one not giving it's all.

To absolutely check your carb, get a spray bottle with some mix gas in it and shoot some in the engine when it starts to die. If it dies quicker, it is flooding,(possible pin hole in the fuel pump) if it speeds up-- it's back to the carb."

"found a carb kit at Linwood Marina. Don't know if they have two. It turned out to be a bad CDI unit; therefore, I was only getting spark for 1 cylinder. May want to check that also."
