I am trying to resurrect a 1984 Honda NH125. This is 2- stroke oil injected.
I rebuilt the carb and managed to get it running but it is getting WAY too much oil. The oil pump is adjusted per the factory service manual and when I run it for a second with the oil line disconnected the oil trickles out slowly.
However, every time I pull the plug the cylinder has way too much oil in it. Oil is dripping out of the exhaust, fouling the plug, and when I turn the engine over with no spark plug a cloud of oil comes out. This is blue two stroke oil so there is no chance that I am mistaking it for something else.
I assume the oil pump is bad? However, if the pump is bad, how is so much oil getting into the cylinder? Wouldn't it be leaking out somewhere lower in the system? What else should I be checking?
I don't want to throw parts at this thing as most stuff is NLA and I am hoping to sell it anyway. Bike only has 2230 miles and the engine has 150 psi compression so if pump is worn out it isn't from mileage.
The pump itself may be gummed up or partially stuck so it's constantly dripping oil even when the engine is off,,,,I'd pull the plug turn it over with the plug out to get rid of the excess oil in the combustion chamber then install the plug and run it till it gets hot,,,I mean run it for ten miles hot,,,then I think you'll find there the right amount being metered into the mix,,,I also think your starting so wet that it's interfering with normal operation,,
