Kohler propane generator won't start
This is a Kohler Confidant 7, 6300watt liquid propane genset. Long story short, last weekend on Saturday I went to show the rv to someone (in the process of selling it), and on the way home, while the generator was running and ac's were going, the thing stopped. I was pulling onto my street so I didn't bother with it, figured, I had to stop it in another hundred yards anyway.
Well, went to prep it to show to someone later today, and the thing won't start anymore. It cranks but it won't start. Pulled the spark plug and grounded it, there is spark. Went and bought a new spark plug from Autozone, same deal. I had just filled up with propane 2 weekends ago, 100 bucks to fill the tank... is it possible I got "bad" propane - or more air than propane or something? I thought propane was cleaner than gas and didn't go stale, so less chance of bad propane? It cranks and cranks, but doesn't start... if I crank it with the spark plug out, should i be able to smell propane coming into the cylinder or is there not enough to actually have a smell?
Being that it is propane, can I spray starting fluid down the intake tube? I haven't tried taking the thing out to get to the carb and whatnot, so I don't think I can get that close...
Any ideas on how to troubleshoot this thing? It's bolted to the rv - not on a fancy slide or anything - so should I even attempt to take this thing out to look at without a cherry picker? I imagine it weighs a ton...
Thanks in advance,
