Stiga 8 hp Briggs & Stratton snowblower

Snowblower was running without engine oil. Piston head got stucked and it was not possible to pull the starter any more. Completely jammed.

I removed:

• Petrol tank (4 bolts)
• Fuel line
• Oil stick
• Choke switch
• Primer with cover
• Exhaust protection and exhaust pipe
• Accelerator switch and springs
• Spark cap and spark plug
• Cylinder top (4 bolts)
• Belts for drive and blower from the drive shaft

I sprayed the WD-40 into the cylinder above the piston head and waited for a few minutes.
Then I took a big spanner and put it on the big nut on the drive shaft. I turned it slowly forth and back a few times since the piston head seemed to move again. Then I turned it all the way around a few times. I filled the engine with motor oil and pulled the starter 15-20 times. Then I used the electric starter a few times. Everything seemed to work like it should. The cylinder walls was ok as well. I putted it together, primed it and fired it up. I worked like it should.
