Sounds like your safety system is engaging and grounding your system. Look for a bad ground or a damaged wire on the coil or on the way to the coil that has a bare spot that may be grounding you out. I will assume that is a generic photo that posted with your question and it doesn’t really show the engine safety shutoff that you hold while the machine runs. Start at that point and work your way to the motor.

I was able to start my 5HP Toro but it is running rough. It wouldn’t start at first so I drained the gas and put in fresh. After several pulls it started. I started it because we are expecting a snow storm. The way it is running I’m fear that when it has a load on it will die out. Is there something I can do to clear up the problem?

ANSWER : Try taking off the fuel bowl and check for debris or ice in it.If there is hardly any fuel in it you may have a plugged or pinched fuel line,try blowing back through it[might get a littl gas in your mouth],turn off the fuel and remove the line at the carb and the tank.If niether of these pick up a new spark plug and try that.

My toro lawn mozer will not start. I have replaced the spark plug, it has gas and oil in it, but it still will not start. What other things can I check myself without having to take it in?
ANSWER : You can check compression,either with a gauge or by spinning the flywheel counter clockwise,if it rebounds sharply then the compression is good. By this I mean just pull the rope slowly and let go,if it sucks up kinda fast you are good.Check the gap in the new plug.Should be 0.25Have some one else pull the starter rope and watch for spark coming from the plug wire,if you see that replace the plug wire.\Check the fuel filters,one in the tank and one in line.Also you can take the carb apart and clean it.Check the air filter.Inspect the fuel line for breaks,or if it came apart somewhere.

I have a toro 620 Z, I have replaced the fuel pump, carburetor, coil, all three fuses, just to be on the safe side, and the spark plugs. I get about 13.43 v off the voltage regulator on all three leads, yet nothing to the coil. What am I missing. It was running fine and it shut off. I replaced the coil, and it ran fine for a while, and shut off again, and now will not start.

Have a craftsman 16″ chain saw 358.360260. Could not initially get it started after it had sat for a couple years with fuel stabilizer in it. When I went to use it the fuel had all evaporated and the fuel pick line was rotted. I replaced that with some difficulty but finally got it on. Saw still wouldn’t start. Replaced the fuel filter. Still wouldn’t start. Pulled the carb apart and cleaned and recleaned everything. Diaphragms were good and I didn’t adjust any of the mixture screws because as I said it ran fine before storage. Non of the carb passages were clogged. Fresh gas 40:1, good spark plug and good spark. Airfilter is good. Engine has maybe about 4 hours of total run time on it. It’s a ZAMA (?) carb. It will run for about 30 seconds when I manually prime it by pouring a small amount of fuel directly though the carb. When I was disassembling the carb the vent hose that goes back into the fuel tank seemed to have a small out of ?substance? in it which I cleaned out. It was right at the end the of the hose that goes back into the fuel tank and not up by the carb. It didn’t appear to be like your typical gummy deposits/varnish though. I hope it wasn?t some type of spongy check valve stuff that is supposed to be in there. That might explain some of my problems. Anyway, I also can not seem to get the primer bulb to fill. When I open the fuel tank, look in side and depress the primer bulb, air bubbles come out of the fuel filter. But when I let the bulb reexpand there’s no fuel that gets sucked up the hose. I can however seem to fill the primer bulb when the fuel tank is full and the chainsaw is laying on it?s pull cord side and the bulb is depressed a bunch of times. The saw will also start and run again for about 15 seconds then die. It’s definitely not getting/fuel and probably running out . Thanks.
