ANSWER: Hello Rogelio:
>>If this is an OHV Engine, then it is Possible the Valve Clearances Require Setting or 1 of the Push Tubes may have Broken/Bent or Jumped Off the Rocker Arm.
>>Send me the Model and Type or Spec Numbers Off the Engine and the Unit/Mower/Generator/ect Model Numbers, Please. With these I can Locate the Proper Manual and Better Assist you. The Engine Model Numbers May be Stamped Into the Blower Housing (metal engine cover) Above the Spark Plug. The Unit/Mower Model Numbers are Usually Located Under the Seat on a Sticker on the Body of the Mower.

QUESTION: I checked what you said and that was the problem,one of the Push Tubes Jumped Off the Rocker Arm. I fixed it and hocked the welder back again and after % min. It jumped off again,(I wonder if the problem is because I'm plugging the welder on it or if there is something else wrong with it.)
Note: the welder is just an AC is not an AC/DC
AnswerHello Rogelio:
>>No, the Problem is the Push Tube is Bent and Requires Replacing, the Adjustment of the Rocker Arms is Required or there is a Problem with the Cam or Lifters.
>>The Following is a Basic File I made for Setting the Valve Clearances. Any Input is Appreciated.
>>**I Do Not Use the Setting Called for by the OEMs. I have Found that the Following Works Best.
>>Remove the Valve Cover (on the Dead Cylinder for Twin Cylinder Engines).
>>Check the Push Tubes and make Sure they are Not Bent.
>>Set the Cylinder you are Setting the Valves on to Top Dead Center on the Compression Stroke When Setting the Valve Clearance. Now Loosen the Valve Adjuster Lock and Using a Blade Style Feeler Gauge, Set the Intake Valve Clearance to .004in -.006in and the Exhaust to .004in - .006in. Loosen and Tighten the Rocker Arm and the Feeler Gauge is Placed Between the Rocker Arm and the Valve Top where the Rocker Arm Pushes on the Valve.
>>***BE SURE TO TIGHTEN THE ADJUSTER LOCK AFTER YOU HAVE THE PROPER VALVE CLEARANCE***
>>I have had Better Performance Out of the Mowers and Less Burnt Valves Using these Settings. Be Sure the Piston is at TDC on the Compression Stroke.**
>>If you Remove the Valve Cover and then Turn the Engine by Hand, you can Watch the Intake Valve Movement. When the Intake Valve Closes, the Piston will Just Starting the Compression/Power Stroke.
>>On Some Engines you can Us a Straightened Coat Hanger and Feel the Piston.
>>Be Careful and Don't Jam the Wire in the Cylinder. Usually the Piston will Push the Wire Out of the Spark Plug Hole with No Problems.
>>As Always, If you Hit a Snag, have More Questions or this Does Not Correct the Problem, I Hope to be Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.
Good Luck
