RE: Engine problems OS 90FS 4 stroke
one more thing I forgot to mention, I think the former owner bent the needles. Becouse at different settings it will lean out then richen up then lean back out. It acts weird. I have done all of what you fellers have said. As I have had many engines 4stroke and 2. But this one just stumped me. I think I will check the valves and then buy a new carb. Unless a miricale happens.
