Snowblower won't start :-(
I know enough about engine repair to know I don't know enough about
engine repair... Storm hit NE yesterday and trusty snowblower won't start. 1. Drained the gas 2. Changed the plug 3. Blew carburetor cleaner in through the gas line to the carburetor It will turn over with the electric starter and let's out a puff or two of exhaust and then stops. I tried messing with the carb float screw (as this had been a problem in the past) but the best I get is it running for about 3 seconds and then stops. This is a fairly new Ariens 8HP model. Can anyone pass on some ideas on troubleshooting? Thanks! |

You might try either and drain the gas and open the float bowl and clean it, add gas with carb cleaner. Also try the old plug, you dont know if the new one was dropped and is any good. |

Is the tank valve open to the carb? Sometimes easy to forget about this. Was the spark plug wet or dry when you took it out? If dry, it is not getting gas. If wet, could be weak spark or bad gas. Check for spark by leaving the plug wire on but leave the plug out of the plug hole and crank over the engine a few times. May be a little hard to see in bright light so look closely. Don't leave the plug too close to the plug hole or it may ignite the gas in the cylinder though. Been there done that. Good luck. Steve |

If wet, could be weak spark or bad gas. If plug has spark but is wet and with new gas, the engine could be "flooded" so try opening the choke and crank over the engine a bunch of times (don't burn out the starter though). Have the throttle control about half open. Steve Also check the gap on the plug. Set it to the proper specs. |

There is a large hole and a very small hole in the body of the valve. You need to spray-out the small hole with carb cleaner or replace the entire assembly and lightly bottom-out the adjusting screw and turn it out one and half turns. HTH |

So I used guesswork to do my mixing and inevitably the oil ratio crept up. I had three seasons of increasingly difficult starts and difficulty to keep running including the necessity to run it on full choke. It was an old machine I inherited from my brother so I thought it was showing its age. I took the carb apart and later the engine apart too a number of times each season to service it. It would work okay for a few jobs then would stall again. It seemed mechanically okay and there wasn't much else left to fix. That left only the oil fuel mix to check up on. Sure enough that lean 50:1 ratio fixed the problem. I can now start my snowblower with a few pulls even in the coldest weather. I need to be very careful to prime the engine with only three squirts of gas. Start with a full choke for the first two or three pulls then half choke. The first sputter and I have to open the choke fully to start. The engine runs smoothly, no smoke and really sips gas. I use less than a liter where before I would use 2 liters. I mix gas only as needed using a 2 liter pop bottle and a dollar store graduated bottle for dispensing 40 ml of oil. The snowthrower tank is topped up after a job so there is very little gas in the pop bottle (minimal fire hazard and cold in winter anyway.) My lawn mower is 4 stroke and needs straight gas that I can use from the gas tank thereby avoid storing gas in multiple containers and having to remember which tank is for what. I need to store only a 5 gallon tank of gas. An 8HP would not have a mix. 8^( |

This year I gave up trying to start small engines (snowblower, generator, etc) at cold temperatures and bought small 50 watt heaters that are attached with an adhesive to the block or oil pan. They provide enough heat to make starting quite easy. Gasoline really doesn't have much vapor pressure at 0 F. http://www.padheaters.com/sizing.html Boden |
