I am using a four stroke Saito 91 which draws fuel better than many 2 strokes, the position of the engine is a little different than the way stated in the manual, I had to use some washers to move the thrust but that's it. The tank rests on very thin foam attached to the tray. Any way while in the building process you should draw a line in the fuse horizontally with the carburetor then draw a line at the center of the tank, make a small hole in the fuse line to check if both lines are centered, ideally the center of the tank should be 1/4" inch below the center line of the carburetor.

Hi alfred,
earlier in this thread there was talk about the fuel tank support being too low.
that is true as the centerline of the tank should be inline with the carb.
My o.s. was hard starting and would not idle. I raised the tank level to centerline of tank inline with carb, and
it worked fine.
Was this the case with your engine? does your engine have a pump?
I also had to do a little tuning because i used a pitts style muffler inplace of the stock muffler, first time with this engine.
It runs great now.
