replaced valve stem oil seals ... Still smoking ! 273 HP

update

gave the 273hp a shot of seafoam down the carb barrels while running then enough to stall it ..... let it sit for 15 minutes .. start it and let her smoke. did this twice .. change the engine oil and see where that takes the smoking issue. used a half bottle did not pour any in the gas tank.
I've seen that seafoam do miracles.
