Hmmm.... time flies.... busy month or so.......
Tech not behaving...... seems the email notification I had set for this thread "fell off".... so am just now catching up on recent interesting posts....
Drew - did you get your battery-start issue sorted out ? I wouldn't want to be w/o a nicely designed pull-start, but electric is convenient....
The comments about Generac had me smiling..... after years in the Tech trenches, I can relate to the performance/reliability/cost perpetual battles.... esp. chuckled re. the Least Worst comment.....
Propane.... it makes sense to me that oil stays clean, but I often think of a counterpart from my Tech Daze when propane comes up...... he'd converted his pickup to propane, and lived in Dallas. Said that the motor oil never noticeably changed colour, but could tell by his (aftermarket) Oil Temp gauge - he paid attention enough (total opposite of grs's customers.....) that he'd notice the Oil Temperature starting to creep up (vs. Ambient/Load/Driving style) as the oil was mechanically starting to deteriorate......
Interesting recollections of the Spring Start engines.... that's one older type I'd never seen myself. Makes a lot of sense, and done well, could be reliable for a very long time........ memories of yesteryear.......
Rgds, D.
