I have installed, uninstalled, inverted, reinstalled, re-uninstalled re-inverted and re-insalled my Magnum .91 4 stroke on a SIG Kadet Senior and the carb is always about an inch above the fuel oulet from the tank.

Will it start and run that far above the tank?; or do I need to invert the mount and bolt the engine to the underside of the mount? Re-locate the mount? Invert the fuselage? Phone a freind? ask the audience?.... curl-up into fetal position and rock myself to sleep?...

Send Prozac!!

Hi,

Move the tank so the centre line of the tank is roughly in line with the centre of the carby venturi, if you are unable to move the motor lower and still retain the thrust lines. One inch is too much for reliable fuel draw without a Perry or Cline pump or similar. If you can move neither the motor nor the tank you are looking at a fuel pump for reliable feed.

Setting up is fun isn't it!!!!!!!!!!!!

Um....

Just so I have a fall-back and to help maintain a weakening grasp on my own sanity.....what kind of fuel pump? I will likely re-locate some things, (including some throwable objects in my workshop), but just in case....where would I find a tiny fuel pump which will run on a battery?

It's not that bad, but I do have a deadline for getting this thing running, (Thursday PM). No pressure.

This will be a model used for work...reliability is a concern, so I will need to get the necessary fuel draw one way or another.

Thanks!!

Hi,

The pumps I'm talking about run on muffler pressure not electric current. They are tiny (smaller than a match box) and easy to position. If you are forced into needing a pump through being unable to position tank or motor you better hope your LHS has one in stock to meet a Thursday deadline.

Heh this hobby is supposed to be fun............not another stress factor in your life.

Good Luck,

Colin

I would say not to worry about it. Run it first.

IF you have any problems (And that's a big "IF" ) then ask.

I have a couple ARF's like this. The tank is already as high as it can go.

Anyway, they work just fine.

Enjoy,

Jim
