Trambia,
I am having a couple issues with my "new to me" '97 ranger. Sounds bout the same. Called a local marine guy I know, he told me to stop buying the cheap gas because it has ethenal content. He stated that the 2strokes do not like it at all. Dont know if anyone else is having or heard of this problem???
I am working on the problem myself, as I have changed plugs, gas filter, gas water seperator filter, added stabil ethenal conditioner.... I am still working on it. He stated that he would look at it after I tried these things, so he didnt have to charge me for simple fixes.
I will ask him if he would like more work, if he does I will pm you his number. Hes a great guy and understand hes a gem with marine motors.
