The back of the case is flat and square, no standoffs needed.
The 1.9 (30 OZ) is as pictured...
Ignition is about 4 oz, muffler 3 or 4 more, depends on the brand...
Engine and ignition, 34 oz..Close to a G26, but no contest on the price...I have not tested it myself, we'll see what it does with my 18-6 Mejzlik test prop...9000 rpm is a hard act to follow
