    Make, model, serial number? If you have spark and compression put some fuel/oil mix in the carburetor throat (McDonald's straw immersed about 2" in the mix, seal your finger over the open end until over carb then release) and see if she sputters or runs. If yes it's a fuel delivery problem and we need to look further. Lou

My 25hp kawasakie motor cranks but wont fire. tractor model 7252. ran perfect 2 days ago. parked it now this problem. where do i start to find problem?


All internal combustion engines need three things to operate (air, heat or spark, fuel). Check to see if you have all of these things, a clean air filter with a clear path to the carburetor, spark at the end of the plug wire (this can be checked by using a screwdriver inserted into the plug wire end and holding it close to a metal grounded surface), and fuel to the carburetor (check to see if you have fuel at the fuel line going into the carb or an easier test is to spray a small ammount of carb cleaner into the throat of the carb just before cranking, if it starts and runs you have a fuel supply problem then check backwards to find the blockage (pinched fuel line, plugged fuel filter, bad fuel pump ect).

If no spark at the plug wire check all connections at electrical terminals under hood and at switches for parking brake, belt engagment (PTO) ect..

Usually if something runs and then just dies suddenly there is an obvious problem, your powers of observation will help you the most. Look at anything that looks out of place.

WONT START


Not so many reasons she won't start. 4-Strokes are Simple!

Here they are:

Motor:
Fuel Tank-> Fuel Line-> Fuel Filter-> Carb-> Intake (Valve)-> Piston-> Exhaust (Valve)-> Muffler

Carb (Old Style):
Fuel Side:
Fuel Bowl-> Float-> Needle Seat-> Fuel Ports (Venturi)
Air Side:
Air Filter-> Carb Air Intake-> Butterflies (2)
(Clean 'em ALL!)

Hardware (Motor):
Rotor (Magnets)-> Magneto (Ignition Coil)-> Spark Plug Wire-> Spark Plug-> Cylinder Head (Spark Plug Ground)

Ignition:
Kill Switches (Seat, Clutch, etc.)-> Spark Plug/Ignition Coil-> Ground
Key Ignition-> Battery->Starter/Generator

If one of those fail.......= Non-Starting 4-Stroke!

Fixes-
Fuel:
You are either getting too much, or too little. Too much = Carb.
Too little = Carb. Therefore, tear down the Carb (COMPLETELY-Careful!) and clean it up.

Electrical:
Grounding out the System (Kill Switches)
Battery-> Ignition-> Starter.
Magneto->Plug Wire->Plug (Check 'em all!)
