honda 2hp lockup problem

I hauled my new honda 4 stroke 2hp engine laying handle side down for 8days. I see that the manual says not to do that. Now I can't pull the starter rope. Anyone know what I have to do to correct the problem? Apparently oil has gotten from the sump into the combustion chamber.

Firstly stand it upright.
Turn off the fuel if you've not already done so.
Pull the kill cord.
Now remove the spark plug.
Gently pull the cord about a few times (you might want to put a rag over the plug whole to catch any oil).
If the plug is oily give it a clean (perhaps in gasoline?).
Refit the plug.
Check the oil level in the "sump" - there is a small sight glass on the side of the engine. It is absolutely critical that the engine is properly level doing this (both in the front/rear and left/right planes). Top up as required.
Reconnect the HT lead, kill cord etc, turn the fuel back on.
Gently pull the started - it shouldn't hydraulically lock this time.
It will take a few pulls to get it to start as everything is oily in there. Beware when it does start it will smoke like mad for at least 5 minutes as it burns off all the excess oil.

Hope that helps.

2HP honda's don't have an "in gear" they have a centrifugal clutch.

It's also possible the sump has filled with fuel. When checking the sight glass, if it appears difficult to read it could be full so change the sump oil before starting. Or, if the amount of oil which has passed the piston into the cylinder is significant, top up the sump oil.

always worth a check though. I cant count the number of times I've seen that on pull start outboards of many descriptions.

Sniff the oil filler hole-you'll smell if there's petrol in the oil.
