It will be best to remove the carb, disassemble, and soak the
metal parts in carb cleaner.
The gas tank should be removed as well.
Remove the fuel fitting from the bottom of the gas tank.
Some models have a fuel filter screen attached to this fitting
which will often need replaced, or cleaned at the least.
I often use a pint of mineral spirits and throw a bunch of
sharp wood screws inside of the gas tank, and shake the
tank a couple of times a day over a few days. Soapy
water and lots of rinsing will remove the loose residue.
Good luck on your project! Hope to see some photos
some time!
Prepare to be boarded!
