Re: snowblower quits running
15yrs old...most likely a Tecumseh....<br />If it is, remove bowl nut(and bowl) from carb and see if gas continues to flow. Note position of float. It should be hanging down slightly below horizontal (or not parallel with carb bowl surface). Fuel should flow freely right on through the seat(around the needle). If no fuel, varnish has clogged the tank barb area. I would recommend replacing the fuel line every 3 years on these. The older fuel lines will not tolerate the newer fuel blends.<br />If fuel is flowing, the next item would be to inspect and clean the bowl nut...this IS the jet-orfice. If the bowl nut has the adjustable high-speed needle as part of it, turn it in by hand until seated lightly, and re-open 2-1/2 turns.(when bowl is back on carb)<br />I would install a new Champion J17LM (RJ17LM is fine too). Before installing the new plug, squirt a small amout of oil in the cyl. and pull it through a few times slowly. Fill with fresh fuel and verify fuel will flow through seat with bowl off, if so, reinstall bowl nut-remember the high-speed needle adjustment! Most of the Tecs. have primers...give it 5 or 6 shots, choke on and it should fire. <br />Always use a good fuel stabilizer and always store it full of fuel/stab mix after running for 4-5 mins. after adding stabilizer.
