I'll start with the starting problems. If I pump the primer bulb until it's hard (it only takes 1 or 2 pumps) then it will actually spit gas out of the carburetor. Once that happens it will not start. I have since tried spraying starting fluid in first thing and it usually starts right up that way. I have also tried starting it without priming or spraying starting fluid in and it just cranks and will not start. Should I rebuild the carbs or is there something else I should check? I have searched these forums for a couple of hours and found 1 old posting about it but it didn't give me any help.<br />Next question is about shifting. It won't shift into reverse until I throttle it up quite a bit and then it finally catches. (It makes it pretty hard to launch, and it is kind of embarrasing) It goes in to forward ok but just not reverse. The weird thing is it will not do it everytime just most of the time. Do I need to rebuild the l.u. or is there another adjustment I should make? <br />Thanks.
