I am having a problem with my two stroke outboard where it will only run with the choke partially closed. I used gas from the same can in my tiller. Same thing happened. Could it be water in the gas? I don't think the gas is stale (it's only a month old). Can this be remedied by adding gas line anti freeze? IP: 65.48.213.102 |

I had the same problem on Sunday. The motor seemed to run better at higher revs. In my case, it was old gas, albeit with some fuel stabilizer in it. I wonder if the oil settles near the bottom of the tank over a period of time. Try shaking the can and mixing up the gas a bit to see if you get better results. I have seen 'oldtimers' do this with their mixed tanks.I don't think gasline a/f will help the problem any. Better to change gas as a first fix. I had a similar problem with the lawn mower (old gas) the day prior, and it cleared up with new gas. My small motor repair guy always asks me if I changed to new fuel first, whenever I consult him regarding a performance problem with my 2 stroke. He states that gas will go stale in a month if sitting in the sun. [This message has been edited by Roger (edited May 31, 2005).] IP: 216.55.202.44 |

Take the Carb apart and clean it. Blow all the jets out with compressed air.Sid IP: 207.200.116.203 |

I just got my two stroke worked on. Ran great two times out. Third time it was wanting the choke. I did have some old gas the third time out but now I am using new gas and it still wants the choke. I assumed it was the nature of the beast. IP: 67.107.33.106 |

I agree with Sid (Hyperstitch). There is no substitute for making sure the problem is gone with a thorough cleaning. When a 2 stroke is put away with fuel still in the sediment bowl, the oil/gas mixture can decompose and make a varnish deposit that can clog the carb. This makes the issue of new vs. old mix in the tank a moot one. It is a good idea to run the motor with the fuel line disconnected to run the carb dry, and then actually open the drain screw on the bowl to empty all fuel, before storing the motor for any extended period of time.IP: 70.71.17.228 |

Another good idea, that I try to remember, is to disconnect the fuel hose, and let the engine run out of gas, after your outing.
When I was down in Florida, the marina had a fresh water hose adjacent to the ramp. We rinsed down the trailer and boat, then we flushed the motor. I disconnected the fuel hose, pulled the cord, and there was about a minutes worth of run time left in the carb, just enough to flush the engine, and run the carb out of gas.

Im a snowmobiler, and I ride a 1973 Kawasaki 750, known as an H2. Three cilinder two stroke. Three Carbs. And I've been riding the H2 since Jan of 1974 as I bought it knew. Now ask me about two strokes and Carb Problems. Clean the Carbs, blow the Jets out with compressed air. Just cleaning the Carbs is not good enough.

I did learn from some of my mistakes from the last couple of years. Last fall, I added fuel stabalizer to the fuel. I pulled the fuel line and let the motor run itself out of gas. I did not however, drain the bowl, although I am not sure that I have one. Starting it up this spring, I had to add gas to the carb and cylinders to get it sucking and (likely) unstick the reed valves, which I have been told can be a bit of a gum up problem. I still suspect that new gas might solve my problem, because it just seemed to want to run rich. Perhaps I should just dump the old three gallons in the truck, and start out the season with new gas.IP: 216.55.202.98 |

To follow on Sid's comments; 2 strokes are finicky and keeping the lines clean are critical. Clean fuel, clean carbs, clean fuel lines. During the sailing season you should also make sure that you run the motor on a regular basis. We're not good at this as we sail everywhere. If you don't run the motor though you can end up with a stale gaseous jello-like gunk in the carb. When you really need the motor; it won't start!D'Arcy "Shortwave" IP: 65.92.115.17 |

All last season my motor was running poorly. At the end of the season I ran all the fuel out of my motor. This spring I took the motor in for tune up. Upon picking up the motor I asked what was wrong. The guy said I shouldn't run out the gas and leave the bowl dry because that only exacerbates the formation of "varnish" in the bowl and on the component parts. He suggested putting stabilizer in the gas and storing the motor full of gas. ?????I have no idea what the best policy is. I have stored with gas and without gas. Either way, the motor runs badly.

Hey guys:Is there any kind of drug that can be added to the fuel to clean the carb? What about a bottle of injector/carbeurator cleaner? Dougster opened the thread by suggesting the use of gas line anti-freeze. IP: 67.70.16.223 |

Thanks to all for your thoughts and advice on this. I would prefer to use the old gas if I can. Not sure what I would do with it otherwise. IP: 65.48.213.102 |

Last time I had old gas...I brought it back to the gas station and asked them to dump it.
I do have a full can of last years gas (mixed with stabilizer) so I'll be doing the same thing this month.IP: 156.34.82.87 |

If you have an old car, 1970's early 80's, poor the old gas in the tank. Use good gas in your 2 stroke motor. You run a two stroke motor at high RPMS and get something caught in the main jet you have a melt down. Good gas is cheaper than rebuilding your engine. Sid

Hi. just working on a lawn mower carb so i thought i'd put in my 2 cents worth.
-if you need partial choke you most likely have a carb problem . clean it,reset it,rebuild it, or replace it.probably just needs cleaning and setting.
-old gas when i have exess gasoline at end of a season i run it through an old dodge work truck (add plenty of fresh gas make shure there are no lumps in the old gas)it dosn't seem to mind . small amonts of old gas go through my snow blower after mixing with fresh. its a big 4 stroke uses lots of fuel
- end of season . drain all of the gas . drain carb float bowl or run it dry. i do this with all my gas equipment and have no problems well maybe a few.
-try a storage oil at the end of season (bombardier,quicksilver)follow the directions on the can . when i hade a motor boat this was part ove my winterizing .
- i personaly don't think gas stabalizers work . i buy less gass more often .little jerry cans are cheap .
-now back to that lowsey mower it was stored for three years full of gas carbs screwed
hope i helped mike

I know this has nothing to do with 2 stroke motors but after seeing Sid at 14,200 feet, I couldn't resist. Here I am in Vancouver at 14 feet above sea level. (The tide is out.)

Nice shot. I'm busy moving into our new home. Not sold the old one yet, so we will take a two to three weeks to get all moved. I may not find my way back on the water till July. Sid IP: 207.200.116.203 |

I used to burn the old outboard gas in the fall in our 1984 Pontiac 6000 with a carburetor. Two gallons of mixed gas per 12 gallon car tank fillup. It obviously benefitted the car, as it's still on the road in 2005!IP: 141.117.228.250 |

1984 Pontiac 6000! I had one too. '84 was the year that fuel injection was available. Mine had a carburetor plus the wiring harness for the injector system.The frame on the front driver's side rusted away. A repair shop threatened to not let it back on the road. I drove it for 2 months while shopping for a used vehicle. I saved the tailight bulbs, the seat belts and the battery. I drove her to the autowrecker and left it idling on the scale. It's all kind of sad. I am loyal to my old vehicles. There are 3 cars in the laneway with a combined total of 750,000km. IP: 65.93.75.218 |

I tend to keep my vehicles at least 10 years also. My '95 Voyager just hit 120K kilometers.
If I do buy something new in the next year or so..it's for towing capacity.IP: 156.34.48.6 |

From 1972 to present I've had only 4 cars.
Two are still on the road.- '72 Fiat 124S 4 door sedan, a poor man's BMW 1800 Could hear it rusting at night while I slept, sold to an Italian kid in '76
Learned body finishing, carburetor and valve adjustments. Trunk was 1/2 filled with neccessary engine spares. - '76 Dodge Aspen 2 door/landau Figured that it would be a nice change to drive a reliable car which wouldn't rust...I learned sheet metal work, pop riveting and body fairing..heh heh Still...It lasted 11 years - '84 Pontiac 6000LE 4 door sedan As I said, STILL on the road. Very little rust, learned advanced instrument panel wiring and power lock bypassing. - '88 Buick Park Ave 14 years and 2 transmissions later it was sold. Learned electric window rebuilding.

Our first car for moving boats around Beautiful BC in the 70s was this classic Euro street machine the Renault 5. Took the mountain roads beautifully. (Not quite as well with a boat on the roof.) Great motor, terrible electrical system. I don't think they have rain forests in France. Carried our 14 a few times as well.
