Tank is 1" deep by 1 7/8" by 3 3/4" tin open uniflow, pinch corner, back corner kicked out 1/8". Cutoff loop does work if I wait until it jumps on the lean, lean step. Engine is upright mounted Fox 35, PA-Fox needle, stuffer backplate, stick in bypass, stock head, tube muffler with 3/8" outlet. Current prop is cut top flite spoon 9 1/2 by 6.3 (10 x 6 cut). Fuel is Byron's 10% with castor and Klotz (50/50) added to get to 27% total oil. Engine has no binding, no rod or shaft slop. Plug is Enya No. 4. Pretty straight forward normal stuff.
Best, DennisT
