Remove the plug and reconnect the coil pack to see if it has a good bright spark. If yes, do a compression test. If you are at least over 100 psi,see that your carb is clean, and not gummed up with old fuel.

What does it mean RM250 wont start even with starting fluid. I have spark.


Hi Al:

Is that a hot blue spark at the tip of the spark plug?

I'd flush the carb, change the gas, spark plug, oil, and air filter.
Then it would probably start and we could go riding.

Compression, spark , timing , fuel for any engine to run. Don't forget a stopped up catalytic convertor will have the same effect as you described. Backfiring of course is fouled plugs, bad plug wires, look for arcing from wires when it is dark outside. If it has a distributor check for cracked cap, had my 91 GMC start backfiring then die due to ignition module inside distributor going bad. It would start back up after it cooled for about 10 minutes.

Stihl ts 400 wont start


If there is good fuel in the tank and the plug gets wet with fuel, and there is a good spark stating the obvious it should go, if not there could be a mechanical issue, piston scored, rings worn etc,

Lawn mower wont start. changed air filter, spark


Does it turn over? If it does, what happens? Does it sound normal when its cranking? I need more information to help. Is it a push mower or riding mower? Does it start by key or pull start?

My 94 gsxr750 wont start it is getting fire the inside of the gas tank looks new no rust. when turning over the engine it dont even sound like it is hitting on anything like the timing is off..i checked...


It needs spark, fuel and air to run. First check all the spark plugs are firing. If they are you could try spraying some carb cleaner in the air filter. If the bike starts up briefly doing this it means you must have a fuel delivery problem.

Oil on the spark plugs is a bad sign. If the method above returns no results the next step would be testing the compression on each cylinder. This requires a special gauge which is relatively inexpensive and easy to use. Hopefully one of these will give a clue as to what is going wrong.

Will start up run for awhile then stall and wont restart


Hello, I would start with a general tune up. Spark plugs and wires, Fuel Filter, Oil Change and Filter Change, Air Filter Change, Some injector cleaner would not hurt eirther. Be sure to lubricate your high mileage car and also use a farily good oil for your motor as well. The run for awhile problem sounds like bad spark plugs. I would change your spark plugs, wires, distributor cap, and rotarty button.

The problem may be with the distributor try to find a cheap used one at a junk yard, the same thing happened to my dads 1990 ramcharger
