Yes, I did misunderstand. I'm sure more power would help in that case.

A 671 has a lot of pull when wound up in first gear, but it does not like low RPMs. I've never faced a slope I couldn't pull in first with the engine wound up.

Please keep us posted on the final outcome of this saga. Curiosity is rampant!!

  I'm just looking for a lil insurance to make it up here, something simple, like a shot of gas near the steepest part of the grade in case it thinks about slowing down. So any thoughts or knowledge on propane would be of interest.
