Leslie, I already answered you on this.

Check your engine cooling pump and all the lines and housing where the pump pumps water into and make sure they are not broken or cracked or leaking . This is called a water cooled engine and has a pump to run cool water through the engine. This could be a major repair.

The voltage regulator/ rectifier may have failed on the motor. What voltage is the motor charging at? Should be in the 13V-14V range.

Take off the top & expose the magneto clean with a fine grit sandpaper that should get fire to the plugs if still no fire u may have.to replace the points

The original plug in that motor was a Champion L-76V. The BUHW is an exact cross reference.

Okay this is on total memory. The shift shaft for a lot of those engines goes right up through the pilot shaft and exits just in front of the block under the carburetor(s). You will see the **** linkage arm connected to this shaft sometimes it's double nutted. See if you can slide the lower unit back up to the housing and put a bolt in it to hold then undue the shift shaft linkage, Remove the bolt and drop the lower unit. Be careful of the water tubes and check make sure the rubber grommets are in place in the pump housing not on the tubes. Clean up the pump housing and install the new impeller kit.
Put the impeller down the shaft on top of the impeller plate, lightly grease the inside of the housing the impeller plate and impeller. Then lower the pump housing down to the impeller while turning the drive shaft clockwise lightly push down on the impeller housing. This will fold the impeller blades all in the correct position and provide lubrication to the pump until the water gets into the pump. To make life easier re-grease the drive shaft spline and the water tube grommets this will ad ease in reinstalling the lower unit. be careful to make sure you thread the drive shaft, water tubes and shift shaft all in at the same time. After installation you may find you need to adjust the **** linkage.
