If it was black smoke, then you're getting too much fuel in the system, which could be a lot of different things...air intake restriction, float in the carb, choke cable, etc.

The ignition switch module is likely to be the problem,they seem to quit for no good reason.The safety relays and fuses are built into the board that comes with the switch and will most likely fix your problem.

Does the engine turn over?. The pto switch you mentioned is this the POWER TAKE OFF switch? In other words starts the deck? If so, it must be off when starting the mower. Any internal combustion motor needs fuel and spark. If it cranks over check for a spark. If no spark determine if it has points or breakerless ignition. Also check magneto coil. If you have spark then, be sure fuel is getting to the carb. With today's gasoline, you can't let it sit in the tank long without adding an additive. If the PTO switch you described, is blowing a fuse, then it cold be a bad coil on the clutch. You can disconnect this coil to see if it stops blowing the fuse. you didn't mention if it is a Kohler or BS engine.

Hello,

There are four reasons for fouled spark plugs, 1, You have a resticted air flow ( dirty air filter, or partially engaged choke), so the mixture is rich all the time fouling tghe plugs. 2, You have a poor quality fuel ( old, stale ), and it wont combust/burn hot enough, then fouling the plugs. 3, You might have a piston ring failure causing engine oil to be left on the cylinder wall instead of being wiped back down, and then burning as part of the combustion process. Thus burning and causingg a rich condition again, and fouling the plugs. Then finally number 4, low engine compression. This is again caused by worn cylinder walls and worn piston rings, causing compressed air/fuel mixture to leak past the rings into the crankcase, and when the fuel/air mixture is compressed then ignited, some of the air needed to ignite the fuel has escaped, and thus a rich condition again, fouling the plugs.


Determining which of the Four are causing you fouling is your next step.

Hope this helps

Why is it that sometimes when you turn the mower off and then try to restart it, it won't start. battery seems OK.


First thing i would check are the battery conections are goog if not clean them up.
Check the fuse connection under the seat, it is for the seat safety switch. It may have became disconnected or blew the fuse.
also
I would suggest new spark plug and fresh gas. You could also take our the spark plug, spray some starter fluid in, put plug back in and try starting again.

1992 celica wont start and now battery is dead


Engine starting depend on the following systems:
1. Fuel system (fuel level, fuel filter, fuel pump pressure etc).
2. Ignition system.(Ignition fuse, spark plugs, spark plug cords, distributor signal, ignition coil, and ignition switch)
3. Battery. (11.4 V - 14 V)
4. Cylinder compression. (145 psi - 190 psi, valve clearance)
5. Starter rpm (250 rpm)

I have a yzf600r. it started yesterday. but then i put in a new battery and niw it won't start. Its like its not getting any gas.


so I take it that the 600 is turning over with the new battery. Did you check the fuel lever? You might have turned it to off when you dropped in the new battery. Otherwise start trouble shooting, Is it getting spark? Take one of the spark plugs out and put the lead wire back on it then touch the bottom the spark plug to metal and turn it over...you should see some spark.Do this to all spark plugs. Then on to fuel, take the fuel feed line off, turn it over and see if fuel sperts out of the line. If all thats good, I would remove the carb. and clean it. Hope this kinda helps :)

My bike has sat for one year. I bought a new battery one year ago and drove it from my old apartment to my current one. The bike has not been started for one year. I got a used gas tank on ebay and...


Ok mate few things to consider here, if the bike has been non started and stationary for a year there is a very good chance that one of the following or all of the following has occurred.
Your battery is dead (they don't like just sitting - doesn't matter new or old, if left for extensive time they will die) Your gear / motor oil would be useless - oil can not just sit in bottom of bike for a year it would be glue
Your carbi would be blocked or partially blocked from fuel gum or varnish in jets
If you like this bike I highly recommend oil and filter change, New spark plug (put about 10 drops of oil down the spark plug hole before you put new spark plug back in to lube the piston) clean air filter (or fit new one) Remove carbi and compressed air clean all jets especially the pilot jet and circuit and stick in a new battery
Once all done for the fist start I would find a nice safe hill and push start it. in my experience under this circumstances if you rely on the electric starter you may find you burn it out trying to start so give at least few minutes running motor to flush everything through before trying to electric start would be your best bet
When you get it going I would dump the oil and oil filter again after 2 hours ride time to confirm all the old expired oil is flushed out - just to be safe
good luck regards Jamie
