Well I must agree. If I try gliding (putting it in neutral sometimes and coasting), planning my stops, driving so I don't strain the engine, go not more than 50 MPH on the highway, then I can get around 45 MPG. If I drive "normally" and average 65 MPH, I get 32 MPG. Now, at the time I was getting the phenominal MPG, I also unwhittingly had something akin to a 3"x2"x1/4" piece of wood inside my aircleaner that rattled around and would basically close off most of the air intake to the carb. In order to accelerate I had to GENTLY hit the gas. To get up to 50 took about 5 miles. If I hit the gas too hard it would bog down and actually slow down.
It turned an impatient, gonzo, banzai driver into someone with empathy for the slow and oppressed. (Still not tollerant of the sloppy incompetent drivers though... they should be blown off the road by a 120mm cannon firing a hyper-velocity KE round - - - maybe even a LOSAT missile. 8*)
