You mentioned 40 HP above not 4 HP? If it's a 4 HP then that should be a whole different set of numbers to look at in the chart vs the 40 HP posted above.thanks for that.
Its im 90% sure its a 4hp, its tiny.
The 2 cylinder " gnat ", was marketed from 76 to 81.----------Not one of their best / most popular machines.--------Got one laying on the junk pile I think.
