You can buy the MC28 manual from Charles (see post above this) which is helpful with many things you'll likely need including engine, transmission, and carburetion. Until the other one is ready this is the best thing going.
Where are you in the states? There are a few of us floating around here. Charles is down south, 2 of us are in Pittsburgh, we have at least one in OH, some sprinkled through the midwest, and then of course a gaggle over on the west coast where we send all the crazy people.
And in case you were wondering - I get my parts from Tyga. There's a link on the ever-changing banner at the top of your screen. Shipping from Thailand is expensive so make sure you're ordering everything you want or it'll hurt to have that 2nd box sent for one or two things.
HTH, Craig
