1997 Johnson 50/35 jet. Motor ran great ~2 weeks ago when out on the river, but in the beginning of my fishing trip, I must of hit a suspended log or something, and damaged the jet. I had to limp back to the boat launch (about 1/4 to 1/3 throttle for about 20 minutes). Since then, I fixed the jet and while I had it off, I also replaced the water pump. I took the boat out this weekend for a test run, and the water pump and jet both seemed to work fine, but my problem now is that the motor idles kind of rough and when I try to give it throttle, just kind of sputters like it either missing or starving for fuel come about half throttle. If I go from idle to full throttle quickly, it will rev up nice and smooth for a spit second, but sputter again. It is oil injected, and runs kind of smokey when trying to run it full throttle. I am going to check compression and spark and replace the fuel filter while I'm at it, just want to try everything while I'm at a lake since I can't really hook up a motor flusher or something of the sort. Thanks...
