THE PREVIOUS OWNER LET IT RAIN IN THE CARB OVER A NUMBER OF YEARS
I COULD NOT CRANK THE ENGINE OVER BY HAND
I TOOK OFF THE HEAD, AND IT APPEARS THAT RUST HAS CORRODED THE PISTON WALLS, AND HAS FROZEN THE RINGS TO THE CYLINDER WALLS. I WOULD LIKE TO GET THE ENGINE TO CRANK OVER SO I CAN GET IT RUNNING...
WHAT WOULD BE THE BEST THING TO DO AT THIS POINT? SOMEONE TOLD ME TO SOAK THE PISTONS IN AUTOMATIC TRANNY FLUID FOR A WEEK OR SO TO DISSOLVE THE RUST... ANY OTHER IDEAS? HAS ANYONE EXPERIENCED THIS? AM I GOING TO HAVE TO SPEND 3K TO HAVE THE ENGINE REBUILT? OR CAN I UNFREEZE THIS ENGINE SOMEHOW...
IT ONLY HAS 35K ORIG MILES ON IT AND WAS RUNNING 5 YEARS AGO...
