Part 3
Electric starter Unit: Replacing the electrical start unit by Pamco was an upgrade that we decided would be in the long run a good decision. The reason for this is because the traditional starter was much more fidgety and can wear out over time. The old starter unit worked by pieces touching to complete the connection of the breaker points. This system while it is effective does wear out and will no longer work not allowing the engine to start and fire. The new system, The original PAMCO Hall effect ignition motor uses the same idea but instead of a breaker point system its a constant connection and the current flows on a timer. This timer is set using the timing light and adjusting the mounting screws. The Drawbacks to switching to this system is firstly the cost. The system costs $100 dollars before shipping. It also comes with a new coil which is much larger and does not mount the same. This poses the problems of where do we have the room to mount whilst keeping the coil close to the top of the engine and how do we mount.
Pistons and Piston Rings: The pistons were in rough shape. We looked at replacing them but we thought with a little elbow grease we could get the pistons back in working order and save the money. The drawbacks of this are if we damage the outside of piston walls we will loose compression. The gist of the job was removing the seized piston rings and cleaning the grooves so the new piston rings fit and moved freely. After about 3 classes of sanding the piston ring grooves and the outer wall we had the pistons back to working condition without sacrificing the compression caused by damage to the piston. Overall this process saved us around $80.00 helping
balance the cost of the Electric starter unit.
