[Shop-talk] Winterizing (summerizing?) an engine?

[Pat Horne]

Scott,

I’d change the oil on it, run it to warm up, then change the oil again, then run it until all the fuel is burned up. 

If you like, spray the carb down & do a plug & filters service. Check the fuel lines for stiffness & cracks. 

Put a little oil into the cylinder & turn it over a few times. Try to leave the engine @ TDC. 

If the carb has a priming bulb, buy a new one before next season “just in case”. 

Peace,
Pat

Guys,

I have a snowblower. It might not get used at all in a winter, it might get used ten times. And I have a long driveway, so I don't want to sell it.

I would like to winterize it such that next October if I want to fire it up I don't have to do what I did this February and disassemble it in the cold to get it to run.

It doesn't have a battery, so this is a gas/carb. issue only.

Is it best to drain most of the gas and let it run until it dies from starvation? Would that leave residue on the jets that might varnish? I'm hesitant to use Sta-bil--I had a bad experience with that once. Drain the gas, take it apart and spray everything with carb cleaner or the like?

This is the first engine I have that might sit for two years straight then need to get fired up as quickly as possible, so I'd like to do this right.

Thanks in advance.
