If this machine has been sitting for an extended period of time it is likely that you have a couple of things going on. First you should drain the fuel from the gas tank. Next remove the bowl from the carb and using a flat head screwdriver remove the mainjet from the carb. Check that it is clear then re-assemble. Next pull your spark plug. Put a rag over the hole in the head where the plug was and pull the engine over a few times. Re-install the plug. Now remove the grey oil dipstick from the engine and check for the oil level being over full. If it is drain the excess.

Doing all of this should solve your issue. In most cases the problem you describe is caused by varnished / rotten fuel, a faulty carb float allowing fuel to drain into the crankcase creating excess pressure or water buildup in the cylinder creating excess pressure.

Start by changing plug. Make sure to ground plug to engine when testing for spark. After go after cable. If resistance is on you'll need to check magneto or coils

Hi, Arm_1951 and the usual suspects are:
1. Spark plugs in bad condition or have an improper gap or are partially fouled.
2. Spark plug cables in bad condition.
3. Battery damaged or nearly discharged, should have 12.5 volts.
4. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
5. Throttle controls not adjusted correctly.
6. Water or dirt in the fuel system.
7. Water or dirt in the carburetor.
8. Faulty fuel pump.
9. Intake air leak.
10. Fuel tank vent hose and vapor valve plugged, or fuel line closed off, restricting fuel flow.
11. Enricher valve inoperative.
12. Engine lubricant to heavy (winter operation).
13. Ignition is not functioning properly (possible sensor failure).
14. Faulty ignition coil.
15. Valves sticking.

Honda Pressure Washer HP 5 not starting

You can try spraying some carburetor cleaner into the carb. If it starts for a minute, your carburetor need cleaning. When you added new gas did you remove the old gas first? Is the air filter clean?

Saw was running and quit checked gas and oil both are full

Check to see if you are getting spark. If you are getting spark then it is not getting fuel. Try sparying starter fliud in the carb. If is starts then stops. Take the fuel line off to see if something is obstructing the line. Also the fuel filter can be changed.
If you are not getting spark with the spark plu relace the plug. Also to check the spark, remove the plug and put a screw driver in the plug wire and ground the screwdriver. a spark should come off the screwdriver

1992 honda accord stop running in middle of driving

When you turn the key to start, the engine cranks over? You must check for spark and fuel, if one is missing, the car won't run. Pull a spark plug, with plug wire connected and plug on a metal surface of the engine, have someone turn the key to start, while you watch for spark at the plug. It is easiest to see spark with car out of direct or bright light. If you have spark, attempt to start several times, pull a spark plug and check for evidence of fuel (wet) on plug. Let me know what you find, we can then continue.
