After sitting for over 10 years in a barn, the PW50 carb was just a tad crusty.

A little cleaning and some micro drill bit work to clear the jets and it runs perfect.
The KTM carb was full of just 2 stroke oil which was odd, but no crud to dig out at least.
It fired right up and runs good with new gas and some good old Klotz R50 oil.
