I got me a good start on a sunburn this weekend too, (even though I worked 9 hrs friday and 9.5 today at work that left the nice sunny sat day oopen to BBQ some STEAKS and put in a barn window, the JINMA still has it's backhoe on, and I need to get the tiller on to finish the garden up. (used the walkbehind some and my brother took over while I framed the window.
I hope I didn't stear you wrong with the spool problem, make sure once you get the cover off to take a good look at the linkages too, make sure all is copasetic. check that hoseout as well.
