Riding Mower wont start
wrote in message ... I have a troy bilt horse xp with a kohler 22hp engine sv620 it will only start if i use starter fluid. i left old gas on the tank so i drained the tank and sprayed it out with ether and bleed the fuel lines to the carb i also removed the diaphram and sprayed it out with ether. I am not sure about that engine,but if there is a brass 'bolt' holding the bowl on the carborator, take it out and look at the holes in it. There is probably one in the top and a very small one on the side. That one on the side is very hard to see.It is probably stopped up. Take a piece of copper wire or something soft and punch out the dirt. Be very careful and do not enlarge the holes in the soft brass. |

Take a piece of copper wire or something soft and punch out the dirt. Be very careful and do not enlarge the holes in the soft brass. That's what I guessed: a bit of watery goo from sitting without fuel stabilizer in the carb. Now I have doubts. If it runs properly once started, it seems to me that the passages must be clear. Maybe the choke plate isn't closing, but I have another idea. My Kohler Command takes a lot of cranking to start if it's been sitting 24 hours or longer. I guess that means fuel seeps out of the float bowl, and the mechanical pump doesn't work very well at cranking speed. I haven't seen anything wrong with the washer at the bottom of the bowl, but I guess I should replace it. If that's the OP's problem, he could prove it with a foot of clear tubing that will fit the inlet nipple on the carburetor. Remove the gas line. Put the clear tube on and use a syringe to add gas until the bowl won't take any more. Remove the clear tube and replace the gas line. Rinse away any spilled gas to prevent a fire, and see if it cranks right up. |
