i use a lot of 2t oil when i do a rebuild on everything
rings, needle bearing,cylinder wall and piston .
i also add 2-6 oz of oil to the first tank of fuel.
you say you have spark? even with a poor spark ether should pop .
caution! remember that ether will strip the oil from parts so use very
sparingly
