Hello,
I have a few questions. First is what fuel to use right now i have been using 87 with a 50 to 1 mix is this wrong should i be using 91 with the 50 to 1 or 25 to 1. will this lower the carbon build up. And the second is the fuel connection on the tiller arm leaks when I prime the bulb to rock hard is this normal. I have replaced the female end do I need to replace the male side and if so whats the part number. The reason i ask these question is becuase it seam to have a little sputter about 2 sec long about every 7 mins. I rebuild the carb. done pressure checks 90 with only 5diffrence.

Your fuel/oil is correct. The primer bulb should pump up hard if the engine is not running. There is an oring at the connector, but if you replaced the connector it should be good. A fuel leak could also let air in the fuel system causing problems.
You might check the male end and make sure it does not have a burr or something cutting the o-ring.
