Starting

Your experience is identical to mine. The gas must evaporate or drain from
the carburetor bowl. I have considered an electric fuel pump just to cut
down on the "cranking" time.

Is it normal that the motorhome has to crank several seconds, 10-15, before
starting?

If I let it sit more than a couple of days it seems to take a long time for
the gas to make it from the tank to the carb. If I start it with in a day
it will start right up.

It's "normal" on our coach, but I suspect that the fuel pump has a leakey valve that lets the gas drain out. I haven't had the
time to diaganose that problem.

According to the guys at NorCal GMC, the engine should fire up with 2 or 3 short tries at cranking.

Hi Ed:

I always pump the gas pedal once or twice then crank-er-over. She
usually starts after 5 seconds or so.

P.S. The new exhaust manifold is in along with the window broken by
vandals.

I just bought a new McCullogh Chain Saw, and discovered that they have
made a tremendous improvement by stealing a page from the past. They
have a thumb bulb manual primer with instructions to push it 10 times
before pulling the starter. It always starts right away, now. Most
airplanes don't have very heavy...read high CCA capacity batteries, but
many do have manual priming pumps and those engines usually start right
away. I see a pattern here.

There are some downsides to the electric fuel pump I recall, but what
about a manual primer?

Wellll, the fuel does have to travel a long way and the pump is pulling
nstead of pushing. Yes, it does take a long time and it wreacks haoc on
the battery. Some owners install an electric fuel pump somewhere down the
line but I have mine close to the engine and just throw th switch on
until I don't hear the pump running.

That usually works well enough to fill the line and put some pressure on
the fuel.

John,

The coach is really starting to look good. I still have to get the electric
mirrors put on yet. I took it back to storage yesterday.

Hi Ed:
I saw you driving down Maple Street yesterday around 4:00pm. Your new
paint job looked great from my side of the road! I tried to get you on
the "GMC" CB channel, but you didn't answer. Maybe it's because I don't
have a CB in my car!
