Many of you probably remember, when I built the trailer for my compressor. After I finished, I had problems with spark. Sometimes it had spark and other times not. If it did not have any, you could leave it for a while and it would spark. I thought about it and I remember seeing something in the engine owners manual that it will work on angles up to 30 degrees. When I pick up the tongue to move it by have I am definitely lifting it over 30 degrees, would this affect the spark?

Not sure what engine you have for your compresser,but some of the newer motors have safty switches in the crank case so it won't start if low on oil.If you have a motor with that switch maybe with it tilted oil isn't registering at switch.Not sure if it goes off pressure or oil level.

I had not thought about that, that could very well be the problem! I will have too look in the manual and see if it has that safety switch. It has a Kohler Command Pro 12.5 on it.

Most likely the "oil level" switch is really a ignition kill switch., No spark, to engine turning either :thumbs:

I looked at the manual, it is 25 degrees, not 30 degrees. But, it did say something about the oil there also. I took a pic of the section.

It sounds like it will still run outside of those angles. Better see if you can find a wiring diagram got it to verify, but it may not have any switch.

It may run outside those angles, but probably only if those angles flood the oil sensor with oil. The really picky position is going to be the one that tilts oil away from the sensor.

I don't know if you have seen this manual, Ryan:

http://www.kohler-en...5_DATE810EN.pdf

Page 3.1 shows one reason for non-start is low oil level.

Page 8.4 gives some info on the oil switch.

There are also wiring diagrams showing oil switch which disables spark when oil level is too low.

Thanks! That is a big help! I will try and see if I can find something to point the finger at tomorrow!

Today, I pulled the plug and did not move the compressor or anything, no spark. I checked the oil and it was full. I did not have time to go through the troubleshooting list.
