    Trip of a life time is starting to get ruined Help

    Where do you find an A/C by-pass pulley? Can that be done with all vehicles? That's something I never heard of before, but could be handy in such a case. Edit: disregard. I just did a search. First I have heard of them! Great Idea if they can find one at the nearest auto parts store for their...

    Onan Generators at high elevation

    I also wondered if my 22 year old Onan was a bit low on compression. I have never checked it, but I will the next time I take the spark plug out. But even if it is low, I will just leave it as is. It's working well enough for me in most cases. I see no evidence of such here in Auburn where the...

    Onan Generators at high elevation

    It's just part of the several reasons why cars / motorcycles run MUCH better at higher elevations than they used to. But perhaps the main reason--seems to do a lot more than mixture, based on several vehicles I have owned. I have removed the sparkplug many times to check. By looking at the...

    Onan Generators at high elevation

    "The new law affects portable gas-powered generators that run under 25 horsepower. These types of generators may be used to power a fridge or other mid-sized appliances." See here. So as long as it's not "portable" it doesn't apply to us RVers. Mounted to an RV should be fine. BTW, there is...

    Onan Generators at high elevation

    It's 2035 and (AFAIK) it only applies to vehicles. See here. -Don- Auburn, CA

    Onan Generators at high elevation

    I find it interesting how at first, smog requirements (early 1980's) were the worse thing that ever happened to cars and motorcycles. Later changed to being the best things that happened when the specs got so tight that efficiency became important and all the engines were redesigned. If it were...

    Onan Generators at high elevation

    Where? Perhaps in my message number 14 above where I said "I realize there is nothing that can be done with rarefied air to get back the lost power". If that 25% loss at 7 K feet, includes modern-day tricks such as a computer controlled advanced ignition and valve timing (which I doubt it...

    Onan Generators at high elevation

    My main point here is that Onan can do many things to help get some of that performance back at higher elevations, just as they did with modern cars. Of course, you're not going to get back 100%, but will get back enough that most people will probably never notice the difference between 7K'...

    Onan Generators at high elevation

    In modern engines, it is done with a computer. In the case of my 1984 Yamha Venture motorcycle, it uses an air pressure sensor to control the TCI (Transistor-Controlled-Ignition) to advance the ignition timing whenever it safely can. Has carburetors and no computer, just the TCI. It runs very...

    Onan Generators at high elevation

    Advanced timing should be much like more compression and get some of that lost performance back. Something that cannot be done at sea level without damage to the engine. If they don't compensate as best they can, I doubt we can expect 50% of the sea level performance. I remember the poor...

    I am still in May, FL?????

    Not really. It decided to stay in Reno when I went to Tom's Place.;) -Don- Auburn, CA

    Likewise, I have not had the issue on that same computer and Verizon connection while here in Auburn. It's been spot on every time I check. -Don- Auburn, CA

    Onan Generators at high elevation

    Since mine is that model (in my Class A) I wonder why it has an elevation setting and choke. I never heard of an elevation setting and choke with TBI. A couple of my motorcycles are TBI and they take care of elevations changes by themselves--no adjustments of any type. No choke. Or did they...

    Onan Generators at high elevation

    The manual for my NEW RV says: "If you travel at high altitudes or in extreme temperatures, your generator can lose power In such lower-density air conditions, you can't operate as many electrical devices as you could under normal operating conditions Power decreases 3 5% for each 1,000 feet...

    Generac generator issues

    Broken start solenoid is a possibility. A flakey smaller relay is also a possibility. So is any remote start switch wiring. -Don- Auburn, CA
