Brent, We also own a 9190 and it seems like when it gets around 35 degrees it wants to start hard also. It has the automatic ether sys. installed and does the trick, but we have found that sometimes it gives it a shot when not necessary and this is not good, so we have resorted to manually spraying a little shot in the air intake after we have cranked it over a little and it will fire right off. It also has 110V grid but we have never tried it. To sum it up I would say that they start up between a 9675, Nav.530 perfect to 7080, 426 liberal ether., Good luck, Mike
