My dinghy sits in the elements 24/7/365.* When I had a boat that was not as "usable" as the dinghy, we would use the dinghy a lot which means the gas would cycle.* Now that I have a boat that is easier to use than the dinghy and offers creature comforts, the dinghy does not get as much use.* In the past, I did not treat the fuel and the only downside was that it would start to run rough after about 3 months with the same tank of gas.* I would get fresh gas and the problem was solved.* SO I thought, "Why not treat the gas with one of the fancy fuel treatment stabilzor thingies?"!!!* SO I did.
I have had nothing but trouble since.* I am guessing but I think the treatment seperated the water and along with it, the alcohol(ethanol).* Because of this, the O-rings on the fuel line connector got eaten up....that fuel line was less than 6 months old.* I put the old one back on and it works fine.* I look under the cowling and it appears that the filter bowl is warped.* There are no symptoms of this right now but I will have to keep an eye on it.* I a thinking the bowl hhas been filtering out the alky/water mixture and caused it to warp as it sat in the bowl.* We went out the other day and every so often, the engine would quit.* Reason........a buncha crap that had filled up the filter bowl to the point of killing the engine.* his resulted in a filter bowl dumping about every 30 minutes and the dissection of the contents was not pretty.
II am thinking in the past, this stuff just remained in solution and the thirsty and indiscriminate 2 stroke would burn it as long as it contained enough stuff to burn.* Now that it is all seperated, it chokes whenever it gets a big mouthful of the seperated bad stuff....
Just an observation.* I hope the rest of my engine is not being eaten alive by this crap.
