Honda BF2D with sand in the engine

[Denngeor]

Without boring you with the details, I managed to get sand into the combustion chamber. Several starting attempts were made prior to me knowing the sand was ingested. The motor did not start. Any suggestions to save the motor?

You find sand in your engine reassuring?

Can you give us an example of something you'd find upsetting, for calibration purposes?

Maybe a Great White Shark?

I'd not be alone in advising a total strip of the engine end of things, which isn't as awful as it might seem.
Page 52 (ish) onwards would seem to cover most of what you'd need to know, with the carb being a few pages earlier, and covered by this very detailed procedure. These aren't complex engines at all, and all spares should be readily available if you need them.
You do say "without boring you with the details"; go on, bore us with the details, all of us have these stories to tell share!

Jamie,
Since you were so kind to provide those excellent links (Thank you!), I will provide the “boring details”. My mate allowed the motor to catch a wave on a sandy beach while in the process of mounting the motor on my tinnie. Unfortunately, he didn’t think it was important enough to tell me. That led to several unsuccessful starting attempts by me which I’m sure didn’t help matters. Thanks for taking the time to reply to my post.

If the motor wasn't running the sand and salt should only be on the outside. Perhaps clean any dried on salt deposits off the ignition system and try again.

Unfortunately, the sea water entered the motor via the carburetor. Too bad the motor wasn’t fitted with an air filter but, I understand why you normally would not need one.
