I did my first fuel line on my 029S a few months back. I never installed one before so I just dipped the bottom end of it in 2 cycle oil and still a PITA to get it seated. I had a pair of plyers pulling inside of tank and tried twisting it, on the topside, side to side and finally seated.
Major pain. Probably wouldn't be so bad if we did it every day like some of the saw mechanics on here. I ran it tonight, leaned out the high just a tad and it ran much better. I have the low set about 1 and 1/3 turn out right now and it is throttling up very smoothly and at the rate I am pulling the throttle trigger. It ran much, much longer tonight than it did the other night. The rebuild kit that I bought was the one off of Baileys. All it had was the diaphragm and all the seals, needle and spring. It did not have the jets or any of that.
