The wheel-bearings of the boat-trailer rusted over our winter, so I've replaced them. Poured the boat fuel into the car, -it deteriorates, but mixed with plenty of new, it's OK. refilled the boat tank. Tried to start the boat.....
Best backfire in my life. Blew the water earmuffs off. Then it caught and ran perfectly. Think the flap-valves were stuck. 2-stroke.

All that's left is to service the reels and check the rest of the tackle.

Life isn't ALL sour grapes and little green apples. Just on principle, some things HAVE to go right.
