Motors should not be laid down on one particular side or the oil will find its way into the cylinder. I don't remember which side that it is but the manual will tell you. If it does get oil in the cylinder, then remove the spark plug and pull it thru until it stops squirting oil out the spark plug hole. Re-install the spark plug, hook up the gas tank, and start the engine in a water tank. It will smoke for a minute as it burns out any oil left in the cylinder and then settle down and run normal.

My Honda 2 hp is a 4-cycle, and there is only ONE side it can be laid down on or oil gets into the carb and who knows where else. I would think (but I don't know) that a two-cycle would be immune to anything other than varnish build-up from old gas. here

Evidently, a lot of the earlier Honda motors were susceptible to oil back draining into the carb if laid on the wrong side, in some cases I’m told even with a little of that kick up your heels & have fun with excessive healing will create problems. If you have the manual, check it. I have a Merc 4-stroke on C27. There’s no trouble with the boat healing, but the manual says it shouldn’t lay on one side or face down. Ferg [links]

My Honda 5hp has been a real pain in the a---!! New in 2003, it does not have many hours on it. I have always religiously run the outboard until it cuts out to run any gas out of the carb before laying it horizontally in the lazerette. But you can never run it totally dry. It seems there are fine little passages in the carb that somehow retain gas which then subsequently turns to gum /jelly and gums up the carb. It took a while to find that problem. An annual stripping/cleaning of the carb works which includes soaking the carb for a day in a bath of carb cleaner. If you do not do this, it does not idle properly, other than at highish revs. I could never see the outboard being ruined but the gumming problem is a PITA. Peter

I had an old honda 7.5 that I lay down regularly but never for that long. Any motor going two years without being ran might have problems. For what it's worth I stored a little two stroke for 5-6 years without running it. The carb was dried out with gunked up jets. But after cleaning it started and still runs. [links]

If you are getting a good price and you believe what the guy said, go for it. The rings may be stuck due to dried oil residue. The carb may be full of gum. But you can get that stuff out with patient. The only reason to buy used stuff is price. So make him an offer YOU can't refuse. All else fails you can still sell it on eBay for a profit.

Re: which side to lay down 9.9 - 4 stroke?

[cronicleu1]

Does it not have a rubber "stand" so that it would lay on its back, with the prop up?

[granerica]

Thanks Guys!<br /><br />Hopefully that manual will show up in the mail soon! [links]

[Metal]

There is normally a decal/label that directs which side to lay it on. As pointed out, there are normally some rubber feet that provide a clue as well.

[MartinaIgnatius]

If it is viscous, clean and has the typical rotting cabbage smell of gear oil then its gear oil. here

[r4king]

If its mobile, black and smells burnt then its old partly burnt 2 stroke oil.

[DevoJinx]

Its is gear oil though is it, not old unburnt 2 stroke oil ?

[ueleniacostae]

Its is gear oil though is it, not old unburt 2 stroke oil ? [links]

[Leonassan]

If it is gear oil then you will need to renew the seals or you will get water intrusion into the gear case. Unlike Seagulls it should not be run on a mix of oil and water.

[tashlan]

I can't say which side as I avoid 4-strokes like the plague for weight reasons, but I strongly suggest you also keep the head up higher than the leg to avoid water filling the head and hydraulic lock unpleasantness. more

As my engine goes in and out of a well and into a locker for sailing I have found rubber car mats are invaluable for the bottom of the locker; I transfer the engine over in upright position - having first let it drain - then slide it into the locker, with the head up on a fender. more
