Hi everyone. I'm new to the forums and new to outboards generally. I've just recently bought a 1991 15hp evinrude tiller steer. She had been setting up for a few years and got a pretty good deal on her. I'm running her on a 14ft. john boat. Motor initially started right up and ran well for a couple weeks and fishing trips with new gas, grease, etc.
Finally, she began to cough and throttle out when I would turn it up. Then it would start up and cut out everytime when I opened up the throttle. I took it in to the local repair shop and they put a carb kit on it. I got it back and took it out for the first time and she ran pretty smooth, but not as fast as it seemed to go at first. Probably topping out around 18mph when it used to plane the boat off at around 25mph. I'm not looking for speed, however, I do want a dependable well running motor as we all do.
Today I took it out and it shortly began doing the same cutting out when I opened up the throttle. It seems to idle fine, but when I open it up it cuts out. Out on the lake today and needed to get back to pier through the wind. I finally resorted to messing with the mixture/lean switch and turned it up about a 1/4 from where it was set and it took off fine and ran well back to the pier at about 18-19mph. I throttled down and throttled up a few times to check it and it seemed fine after I increased the mixture. I don't know if it is good to run it at a higher mixture and if it would hurt it in the long run. Also, when in neutral and I throttle it all the way up, it begans "clanking" a little when I throttle back down. Only does this in neutral.
Before I take it back to the shop and complain about spending $100 on the carb kit, I wanted to get some suggestions. By the way, when I say "mixture," I mean lean/rich adjustment.
Thanks for all help.
