Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello, my name is ***** ***** I am going to assist you with this.
Could you please provide some detail here?
Is the genset running well, good and smooth?
Is the A/C the only thing that is not being powered, or are there other things that are not being powered?
What happens when you try to turn the A/C on?
The more detail you provide, the easier and quicker it will be to find the problem.
If it is running that hot, it is not good.
It indicates that the engine is running too lean, either a bad carb, or an air leak, or the valves may be out of adjustment, or the muffler is restricted.
Check the altitude adjust on the carb, and if it is not already open all the way, open it up.
Since this is a new carb, we will assume it is good, but still keep in mind that it may not be.
I would also recommend adjusting the valves before going on.
Let's see what happens with that.
It depends on how the genset is mounted in the coach. Sometimes they have to be removed, sometimes they do not.
The intake manifold has to come off to be able to adjust the valves.
Side clearance doesn't matter - it is overhead clearance that you need.
If the gen will run all day with 1 A/C, it is extremely unlikely that the fuel pump is the problem.
What do you mean by "shed power" exaclty?
And how often is "often"?
You need to be specific and detailed. Remember, I can't see or hear what is going on, and I only know as much - or as little - as you tell me.
Get the valve adjustment done, and lets see what happens.

No, you do not need to do the 7 day trial thing if you do not want.
Not sure why you are testing the ignition system. If the engine will start and run, the ignition system is working.
But if you are testing it, it is best to disconnect the ignition module wire from both sides of the coil, and just test the module. It is possible for the coil to interfere with getting an accurate reading.
The ignition module only has 2 wires - red and black. They both go on the coil, red on positive, black on negative.
No, you can still have good compression even if the valves are out of adjustment.
That's different. Usually it is the exhaust valves that come out of adjustment.
Since everything else is checking out, it is pointing to a lean running condition - either you have an air leak somewhere in the intake, or the carb is not set up properly, or is bad.
Timing is not adjustable. It is either in time, or the engine won't run.
The hot exhaust is due to the engine running too lean - either an air leak at the intake, or not enough fuel going through the carb.
