Well, I don't have a service manual, but last Thursday, I punched in my Paul Short BX 25 repair video and reviewed it while having a cup of coffee. Then I tackled all the filters, changed the oil, tightened everything and put the machine back together. The fuel filters took the longest, mainly because of the crummy clamps and the fact that it was the first change for them. I guess I'm visually oriented, due to the fact that TV was the great new invention when I was around 8 years old, and I watched it for hours. If you need help with service, watch this video.:thumbsup:
