Do NOT change the points as the replacement points available these days are pretty much junk in comparison. LIghtly dress the ones you have. You will need to change the condensers. Your old condensers may be leaking and be the root cause of your weak spark. These will be .22mfd. This engine needs to be run on no less oil than a 24;1 mixture. The older 3-ring pistons pretty much demand it. Billy Bob and Bubba may tell you different but you will never hear of an early engine dying from the correct oil mix. Your compression will come up once the engine has been run. Compression gauges are all over the board with readings. Very few will read the same. You will absolutely need to change the water pump impeller. May need to do a carb job and if so only buy an OEM kit. It is the only complete kit on the market. Marine engine is your source for parts information and purchasing. Double line fuel line is still available as well as are fuel tank diaphragms and kits. </blockquote>
