I have a new 3W-157. The plane will not be here for few months, and I need to sore me engine. Here is what I did--please let me know if I missed anything.

I put a tablespoon of 2-cycle oil into the spark plug holes, rotated is few times to coat everything and put the plugs back; attached headers and sealed all orifices (exhaust and intake) with plastic bags and scotch tape. I also put a piece of gas line on all carb tubes and plugged the holes to make everything airtight.

Engine is stored indoors in a dark place at room temperature.

Am I forgettign anyhting?

Thanks
