In our last episode, I was fired by my mechanic for asking if a two-week delay in asking for a deposit would mean a two-week delay in getting my boat back. Now four more weeks have passed, and we finally have our '98 Sportster 1800 back from the second shop. It has a new (refurbished, I guess) 717 on the port side, and also what the bill calls a couvercle rotar and valve. The mechanic said a screw from the carb had come loose and been sucked into the engine causing all manner of damage. Even with the rotar and valve (about $275), the total cost was a bit less than the price quoted by the shop that ultimately fired me.
The shop manager said they tested it in his tank before we picked it up on Friday afternoon. When we got it to the lake Saturday afternoon, the new engine started right up, but the older one (which is not original -- it had been replaced at some point) gave us fits. Would. Not. Start. We finally primed it with starter fluid (which is a pain in the butt) and got it going, and everything was fine. After a few minutes, we stopped on the water not too far from the dock, stopped the engines and then tried to start them back up. Again, the new one fired right up but we ended up having to prime the old one again. After it started, it was fine. When we got back to the dock to go home, I tested again and both engines started up fine.
This morning, we took the boat back out. The new engine started right up, and the older one was contrary again -- even more contrary than yesterday. Starter fluid didn't work. My husband took the air filter off and poked around. Finally it did start. It would die at idle speed but start right back up again. When we got out of the no-wake zone and into the open water, it was great. Just great. Fun fun fun. We cruised for about an hour. When we got back to the no-wake zone, the old engine died at idle speed. But it would start right back up. Also started right up when we got it back to the house. So... we are soooooo close to having this thing running right, but I think we need to adjust the idle speed or maybe the fuel/air mixture. Suggestions are welcome...
