Gasahol Blues
For years now, I have been fighting the problems keeping my 4
stroke Ymmaha T9.9 running. Even with adding preservatives to the gas tank, replacing the fuel delivery system, and adding a 19 micron filter inline with the gas feed, the tiny jets on this engine occasionally block up. Nothing helps short of tearing down the carb to clean them. Most of the modern gas engines have these small jets that continually block up. Gasahol is mostly to blame either because it dissolves any loose dirt in your system or breaks down into something that eventually blocks the carbs. Now we have an increase of alcohol being pushed by our farmers to 15 per cent instead of the current 10 percent. This is sure to make the problem worse. The engine manufacturer's have not come up with a really good solution. Just band-aid fixes like adding inline filters and preservatives to the gas. This is taking all the fun out of boating and can even be a safety issue. Sherwin |

The key is recognizing the 90 day life of this fuel. After 90 days it starts to gel. You must empty the tank, flush the fuel line
and drain the carb before letting it stand or suffer the consequences. It's a pain, but it only takes a few minutes. Steve "sherwin dubren" wrote in message ...

Makin money! BTW, the problem in the 4 stroke little engines is an epa deal. There is a hidden adjustment on most. On the Hondas, there is an adjuster on the side of the carb that is limited by a little cap. Use a little torch to heat the solder holding the cap on. With the cap off, a little extra turn and the engine will run great. The Yam probably has a cover over the adjuster as I had on a little road bike. G |

Getting a finer grain filter is a no brainer. Nothing helps short of tearin down the carb to clean them. Most of the modern gas engines have these small jets that continually block up. If you quit putting known dirty gas in your equipment that will help.

Then pour off the upper gasoline layer and discard the lower water layer that has all the alcohol in it. Get the local fuel dealer to drop off a 300 gallon barrel. You can add the water and stir with compressed air, then drain the water. Casady |

You can add the water and stir with compressed air, then drain the water. Will that change the effective octane rating of the remaining gasoline? Ethanol, and the methanol my car uses, propane, acetone, toluene they all rate 100 octane. If you take it out it will lower the octane three points or so to the level you have with the upblended gas sold as such. Casady |

I have been using this in my boat and ATV for years will good results: http://www.seafoamsales.com/motor-treatment.html It's a lot cheaper than Yamaha's version of the same product. |

That stuff has a good reputation but After putting two cans of the stuff through the fuel system on my bike I still had to have the carbs cleaned. -- Me |
