Having thought most of the bad problems were gone last year, a new one has come to light.

The coach has been in the drive over Winter. She was driven there directly from the Mechanic. A lot of running had been done in the effert to find and fix the power loss problem.

I ran her a week ago and noticed she had trouble holding a good idle speed after warming up. I shut her down.

The other day I tried to start her and only had sputtering and then just cranking.
As I knew the fuel was low, I pressed the RESERVE button but to no avail, just cranking. I even put gas in the bowl in the carborator to help. She ran for a sec or two then down again.

I began assuming she was out of gas but the RESERVE should have supplied some fuel, about 25 miles I think it is, but this save did not happen.

I put 4 gallons of gas in and she started to run again.

The fickle finger is pointing at a bad reserve.....

Can the reserve wall fail in the tank? anyone ever hear of this or maybe the valve could fail?? I can hear the valve clicking when the switch is hit...

Or maybe the main/res valve is not working?? can that be when I can clearly hear the click of the solenoid???

If I were to pull gas line to the gas pump, how would I prove one or the other is working?

As always, any ideas are appreciated....

LarC ( Thinking the Reserve barrier may have come loose inside the tank making the RESERVE supply a memory )
