I have a model year 2000 200 EFI Merc. It sat for a month or so. I took it out to the lake to test a new kicker I had installed. When I went to start the 200 it ran very slowly and would not allow any additional throttle or it would quit. After a few of these starts and stops it began to stop immediately after starting. I would crank it, it would fire like once and kick out the starter then quit. Over and over again. I drifted around the lake a while testing the new 15 hp and then went to try starting the big motor again. It acted like it did at the doc. It would start and run very weekly for a bit but would not allow any throttle. After many attempts it finally allowed me to advance the throttle in neutral. After revving it a bit it seemed to clear up and then ran fine for the rest of the morning.
When it initially started and kept running it smoked a LOT for a minute or so then cleaned up. It has been smoking a lot after sitting a while for some years now but never refused to start. Could the oil injection be leaking or something like that?
Looking for any suggestions as to what might cause this. The primer bulb remained firm during all this.
