Calling Kohler experts
« on: January 20, 2014, 08:17:02 PM »
I try to start my generator every month and the last two times it was hard to start.  Nearly ran down the battery today.  It runs and idles fine once it starts.  The engine is a 674cc Kohler.  Even after running for 5 min. it still needed the choke to fire off quickly.
I drained out all the old gas and it looked a little yellow.  I ran the gen for several days this summer so the fuel is at most 6 months old.  The engine has 98 hours so plugs, etc. should be good.  I'll try it with the new fuel in the morning and then where do I look?   Plugs, fuel filter, fuel pump.  The fact that it runs with good power after starting and idles smooth makes diagnosis a bit tough.  With the weather we have coming I  want to be sure I can get it started.  I'm listening small engine guys  :D

I usually only start up my generator twice a year, (assuming I don't need it for a problem.)  Mechanic I know strongly suggested I add Sea Foam additive and have been using it in all my power equipment since.  Haven't had a problem with any of my gas equipment since.

4 or 5 years ago, I had a conversation with a guy who is a small engine engineer. I complained that it seemed like every year I was rebuilding or replacing carbs on my various small engines. We talked about fuel additives and he recommended some stuff called "Pri-G". He claimed it was the best on the market...I gave him a ribbing but he insisted that he had no financial arrangement with the company.

I have used it in every small engine (ranging from 2--38 HP both 2 stroke and 4) and haven't had a problem since. In one small tiller, it had 2 1/2 year old gas in it treated with Pri G and it started right up and ran like a champ.

A lot of these engines are seasonal use.  I just top it each one off with treated fuel and 6-9 months later they all start like they have fresh gas.

OK, 18 deg. this morning and with fresh fuel the engine started on the first rotation.  How do we get around this rotten fuel?  Will going to a higher grade help?  I would think it would still have alcohol and that is the problem, Right?  My 4 wheeler was getting hard to start also and new fuel fixed that too. 
I'll try to locate a service station with alcohol free gas today.  I want to keep my generator full of fuel but this gas will not work for that.    There is no way for water to get in the generator fuel tank unless in was in the fuel as it came from the filling station.  The fuel that I pulled from the tank was really yellow so I know it was  bad.

Cousin Rodney told me that the 89 grade and above do not contain ethanol.  How can I know if this is true?

Our pumps have to be marked if the gas contains ethanol. I've noticed that if there is no ethanol, it is also listed as "recreational gas".

Well it was definitely the fuel.  I've started it every day now and it starts instantly at sub 0 temps.
