Ignoring all the stale fuel etc issues, skyemutt is putting it ion the back of his car.

Bottom line is carb floats are designed to work by floating, so as soon as you turn the thing on it's side / back / front / any angle other than the right way up, the bowl seal is broken & the fuel will dribble out into the carb then onto the air intake & the car will honk of petrol for days after.

So, theories of deposits aside, I'd be empting the carb(s) regardless......

I run mine dry by simply disconnecting the fuel line - its incredible on idle just how long the engine runs for, mine went for at least 2 minutes before it finally cut out!

I agree - I pull the fuel line off just before I jump out, by the time I've walked up to get the car and put the trailer in the water it is just about to run dry and conk out

That's interesting as I have an autolube 2 stroke. Now should I disconnect the fuel or not if it's going to be left for at least a week unused?

That autolube could give problems when run dry.

Depending on how the autolube is set up, it furnishes oil depending on pressure or engine speed. As the fuel mixture leans out, you may find excess oil injected.

As it was probably run in on essentially a 25:1 mix for 10 hrs I doubt that will cause any long term damage.

Probably the best way to find out would be to run all the fuel out and pull a spark plug to examine. If the plug were fouled badly, then the pump put too much oil in, but as long as the oil did not go through the carburator it would not hurt anything.

Our old Evinrude only put a small ratio of oil to gasoline at idle speed, so it may be no problem at all to run it dry.
