Re: Is overhaul worth it?
Hi, colslik. I think that is the 2 cyl. looper. That engine was 20 years ahead of the industry, so it is worth making it run. If it was running well when stored, it probably doesn't need a full overhaul. Jack is right about fuel pumps and seals shrinking. Carb gaskets also dry out, but I don't think seals and carb gaskets would prevent it from starting. Lack of fuel would, stuck rings would, and lack of spark would. <br />Quickie fuel pump test.<br />Disconnect one fuel line from the pump at a carb. Stick it in a bottle or can and spin her over. If it pumps fuel into the bottle or can the pump is working. Put the line back on. Do this outdoors with no flame or spark nearby.<br /><br />Quickie compression test.<br />Pull both spark plugs. If you have no compression guage, stick a finger in to block the hole. Spin it over. If it blows your finger out, you have compression. If you have a guage, you should get at least 100lb of compression and the two cylinders should be within 15 lb of one another. Finally, check that the spark plugs are slightly wet after trying to start it. If they are dry, you are not getting fuel from the carb(s).<br /><br />Quickie spark test.<br />Pull one spark plug. reconnect it to the plug wire. Put on a pair of her nib's rubber dishwashing gloves and hold the base of the plug against the block while turning her over. Repeated sparks should be visible.<br /><br />If it fails any of the above tests you know where the trouble lies. A fuel pump kit is an easy, do-it-yourself project. If you don't have compression, squirt about 1 tsp of oil into the bad cylinder(s) and try it again. If compression improves but stays weak, you have stuck rings. If that CD ignition has failed you will need more specific instructions . . .I have the Clymer book on that engine and can guide you through troubleshooting the ignition, or if you are not inclined, take it to a pro. If both carbs are failing (fuel pump okay, plugs not wet), same thing. If it passes all tests and still refuses to pop I was wrong about leaky seals. Take it to a pro.<br /><br />Hope this helps. Happy boating.
