Force 45 sitting for at least 10 years

[arkyfan8588]

Any idea and suggestions on what to do and where to start would be awesome! From the information I've gathered the engine won't stay running once it's started. Maybe a air/fuel mixture problem? Planning to drain the fuel and add new soon. Does it need to be ethanol free? I'm seeing a 50:1 mix for the fuel. I know nothing about two stroke so some advice on that would be great as well.

Don't need to be ethanol free but the ethanol could damage your carbs and hoses if left sitting for to long. My experience is that it evaporates out the carbs before any damage is done, leaving only the oil behind.
A 2% mix should be fine.
The stalling problem could be a clogged up carb or more likely the reeds.
If you can get it going for a least a few seconds, hold a piece of paper behind the carb and see if it gets wet from fuel! If it does you have bad reeds.
Do a compression test. Testers are cheap and useful for other things as well. Both plugs out, attach tester, full throttle and then crank on a fresh battery till the gauge stops. Should be within 1 bar / 15 psi of each other.
Be sure it's in the water or on a hose before attempting to start, even a few seconds without water will damage the impeller.
And last, change the gearoil before you sail it.

I see a lot of posts from folks who have a motor that has been in storage, belonged to their dad or granddad, or for another reason. I recently went through most of these steps myself in preparing a motor which hadnt been used for 15 years. Following is an attempt to provide a concise list of...

That's some solid advise right there...... And a nice checklist to go by!

I hope the OP is not as lazy as me When I bought my 78' Chrysler I didn't change impeller and still haven't yet!
Sometimes it's nice to know if the engine could work before you prep it to actually work.
But if you get it to start and idle, the impeller and new gear oil would be on the top of the list before going anywhere.
