Question
Engine tag
Hi John!
I'm contacting You from a snowy Sweden. Now to my issue...
I have HM100 with a stuck piston. Ive fixed it once by opening the head and gently knocking the pistontop with a rubber club. This made the piston come loose so I changed the oil and gaskets and put the darn thing together. It started nicely but it ran just a few minutes, the it suddenly stopped, with the piston stuck again. My guess is that one of the rings are broken and wedged between the piston and cylinder wall, the problem is that I dont see how to remove the cylinder to evaluate the pistonrings without tearing the whole engineblock apart since the cylinder seems to be casted together with the block. Do you have any pointers on how to move on.

AnswerHello Kent:
>>I am Located in Leon, WV USA. I Hope you are Doing Well. The Weather here is Now 50 Degrees and a Warm Southerly Breeze, but the Darn Ice and Snow will Not Melt. LOL.
>>The Engine has to be Removed from the Unit and then Disassembled.
>>The Following is a Basic Instruction File for Examining the Inside of a Small Engine and will Assist you in having Access to the Governor, Oil Pump (if Applicable), Cam Piston, Connecting Rod and Crankshaft Gear. Any Input is Appreciated.
>>**This is a Simple Process. Drain the Oil and Remove the Engine to the Work Bench with the Oil Pan Facing Up. I have a Wooden Rest that was Especially Made to Hold the Engine when in this Position.
>>Using Fine Sand Paper, Remove ALL the Rust and Debris from the Crankshaft.
>>Remove ALL the Oil Pan Bolts.
>>After All the Oil Pan Bolts are Removed; Tap Lightly on the Sides of the Oil Pan to Loosen it from the Dowel Pins.
Sometimes you May have to Use a Flat Screw Driver or Chisel Between the Oil Pan/Sump at the Areas Neat to the Dowel Pin and Loosen the Oil Pan/Sump.
>>When the Oil Pan is Removed, you can See the Governor Resting on Top of the Cam Gear.
>>****If Required: Lift Off and Replace with a New Governor. Check the Engine Block for Debris from the Old Governor and Wipe the Inside of the Block With a Rag, Until Clean. Set the Governor Shaft So it will be Resting on the Governor whine the Oil Pan is Replaced and Carefully Replace the Oil Pan. If the Crankshaft Seal Was Not Leaking, then Leave it Alone. It Should be OK. You can Easily Replace it While Mounted on the Machine if Required Later. Make Sure the Governor Stays in Contact with the Governor Shaft while Replacing the Oil Pan. Re - Mount the Engine to the Machine. Refill With Oil. Your Internal Governor May Differ.****
>>From this Point it should be Fairly Easy to Remove the Piston from the Engine Block.
>>If the Cylinder has a Gouge or is Damaged, then a Short Block or New Engine is Required.
