I have successfully rebuilt the carburetor on my WD45 and it actually started and ran! I used some info from the archives and the tune-up video to help get me through it.
I have a couple of other questions now - I'm considering an engine overhaul including new sleeves and pistons, and possibly sending the head off to have the valves and seats ground. I don't have the tools to remove the engine (a cherry picker or engine stand) and wondered if anyone here has done an in-frame overhaul? Seems like the easiest way but thought I'd check.
Also, the right rear tire is going down a little so I tried to put some air in it. As I understand it there is supposed to be fluid in the tires up to a certain point and then air added to make up the correct pressure. When I put the air nozzle on the valve, with the valve at the top-most point in the tire travel, fluid squirted out of the valve and out the back of the nozzle. Are these tires supposed to be completely full of fluid? It might just be that the air pressure pushes the fluid out, but I couldn't get any air in the tire.
I really appreciate all the help and expereince here on this board - I wouldn't have a running Wd45 if it was for you guys!
