The first thing i did was pulled the plugs and put KROIL into the cylinders to free the piston rings and every nut, bolt, dohicky I could find.
I pulled the flywheel to replace the timing belt;
They're not kidding about the chore of pulling them. Tighten the puller to the point you think it should go and then tighten some more. You will find it still wont come off so tighten it to the point something should be breaking and strike the center bolt of the puller with a hammer and it will pop off.
The timing belt pulley is connected to the bottom of the flywheel and there is little clearance between the pulley and side of the housing to slid the flywheel off. I gently rotated the flywheel working the belt off the pulley for some time. Installation is the same way.
I changed the condenser, cleaned the points, and oiled the wick for the points cam.
An off set, opposing, right angle screwdriver will come in handy for removing the distributor and magneto caps as someone with a sick sense of humor and small hands built this part.
The water impeller replacement is straight forward. Remove the anode, the nut under the anode, the nut near the anode, and the two nuts under the anti-cavitation plate. I use a bit of grease to help get the new impeller into the housing.
The carburetors on this motor have been made for years and many of the parts are available from Mercury. As are the check valve kit/fuel pump kit and the fuel lines.
The carbs are easy to rework. Keep the parts and work area clean and count the number of turns when removing the idle needle. This will help when you go to start the motor.
The fuel pump is simple but the screws that hold the check valves can stick. Take the housing and place it on a sturdy piece of wood on the floor. Apply some good penetrating oil to the screws. Insert a #2 philips screwdriver into the screw head and firmly strike the back of the driver with a hammer. Let it sit overnight and the screws may come out.
While installing the new spark plugs I found the spring coil at the ends of the wires have rusted way.
After 35 hours and some swearing I was ready to start the motor. I mixed the non-oxygenated gasoline and oil at 24:1 and added 1 ounce per gallon SEAFOAM. The motor is a pull start (WHAT KIND OF SICK PERSON HAS A PULL START 4 CYLINDER) and it fired the third pull only to have no water coming from the pee hole. I found some mud in the hose coming from the top of the engine.
All said and done i had the motor running/smoking out the neighborhood for an hour last night and a brisk idle.
