Hi All,
OK... I was going back and forth on weather I should make this post or not. In the end, I decided... yes so I could make a couple points. Also, I'm making the post in the general section because this is general info.
OK, some of you may know that I picked up a Polaris project cheap, and as with any "New to me" ski or boat... there are a few things I do. These things include, changing fuel lines, changing plugs, checking compression, draining the oil and fuel, bleeding the system, checking the pump, checking the drive shaft seals, and REBUILD THE CARBS.
So, after a couple trips to the lake, and finding a few electrical issues... the big Polaris Genesis was ruining great! So, I decided to throw a little money at it, and make everything work. The main thing that it needed was a start stop module.
The module needed was a simple start/stop unit, and it controlled the "Switched" 12v supply. It is only a few wires, and a no-brainer to install.
Well, it showed up last week, and I threw it into the ski. Last Saturday, I invited the neighbors out to the lake to play with some of my toys, and after a short ride, the Polaris wasn't reving up like it should. It was running absolutely perfect, but it was only getting up to 5500 rpm. (7200 is it's red-line)
Once back to shore, I found the front spark plug was cold. We tried a few things, but decided it was best to just park it for the day. (there was a boat and my Si to play with)
On Sunday morning, I checked over all the electrical again (the obvious thing, since it ran fine before installing the module) I couldn't find anything wrong, and the front jug had a strong spark. So... off comes the carbs. (even though I just rebuilt them)
As soon as I sat down at the work bench, and opened the diaphragm cover on the #1 carb... I found the problem. The screw holding the jet plate on, vibrated out, and was keeping the diaphragm from opening the needle and seat.
OK... so why did I make this post???? (or, the moral of the story is)
1) Just because you rebuilt, or checked a part... that doesn't mean the problem isn't there. (please listen to the forum pros when we ask you to double check something)
2) Just because you worked on one part, doesn't mean that the problem isn't somewhere else. (things happen during transport, or between rides)
3) Finally, Pro's (or semi-pro's) on occasion can miss something, so be nice to us if we don't figure out the problem on the first try. (we are just human)
BUT... in no way is this a defense for a local dealer who's answer for every problem is to just start replacing parts. A legit shop... if they rebuilt your carbs... and found this, after a a complaint of poor perfomance... they would have fixed it at no charge.
You can now laugh and point fingers at me for not tightening a screw.
