QuestionThanks for the link. I have taken a flywheel off a Tecumseh lawnmower engine before to fix the safety switch. I assume its the same method.
When its off, is there anything in particular I need to look at to see if the flywheel key is damaged? Where does the flywheel key sit exactly.
thanks.

Thanks for the quick response John.
Do you know any good books that I could get more info on taking apart the engine to get at the flywheel key? or a website with a step by step. I am pretty handy around the outside of engines, but havn't spent much time with internals.
thanks again.

Hi John.
I bought a used Honda HS35 snowblower last year. It ran fine for the first few minutes when I bought it, then all of a sudden when I hit an icy snowbank the motor died, and when I started it back up since it does not run at full throttle anymore.
I can start the engine fully choke and it will run at low RPM for as long as I keep it choked. As soon as I open up the throttle, the engine starts to speed up until it gets to a certain point than dies down, and the RPMS surge up and down and I can never get it to run at full speed.
While its doing this its backfiring as well once in awhile. If I move the level that is attached to the carb that attaches to the engine itself, sometimes I can move it enough so that the engines RPM speeds up and its almost at full speed, but when I let go of the lever, the engine dies down again and barely idles.
Any ideas? I have cleaned the carb a few times now and am pretty sure it is clean. Does it sound like a timing issue or something inside the engine?

Hello Matt:
If the Carburetor is Clean, then Check the Flywheel Key. If the Engine Came to a Sudden Stop, the Flywheel Key May be Damaged. The Flywheel has to be Removed to Check the Key. The Key times the Firing of the Spark Plug. From your Description, I Suggest you Check the Key. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.
Good Luck

Hello Matt:
It is a Simple Repair. An Illustrated Breakdown/IPL should Help. Go to this Addy http://www.honda-engines-eu.com/en/service/spareparts/heepartscatalogue/index.js and Enter the Model Numbers and Type Letters from the Engine. The Blower Housing )metal engine cover)is Removed to Expose the Flywheel. Then Remove the Center Nut from the Flywheel. Then Use a Steering Wheel Puller; Attach it to the Flywheel and Apply Pressure. Then Hit the Top of the Puller with a Hammer and the Flywheel Should Jump Loose. You May have to Hit and Re-tighten the Puller Once or Twice. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.

Answer Hello Matt:
Just like the Tecumseh, the Key Lines Up the Flywheel with the Crankshaft. If the Key Shows Ant Signs of Damage, Even what Looks like a Scratch; Replace the Key. Hope this Helps. I am here if you Require more Assistance. Let me know what Happens, Please. Thanks.
Good Luck
