Morse lever creeping back in use ...

[Refueler]

I have the following old style Morse Single lever on the VP AQ170 ...



It works fine - clutch is easy .. lever moves without any grating or signs of wear ... but if set at a low to mid range throttle lets say 1500 to 3000 rpm - the lever slowly moves back to idle .. if I set at higher - lets say 4000+ - the lever tends to stay where put.

Is there any way to stop this ?? It means at lowish setting - need to rest hand on lever ...

Morse used to sell a cable clamp that applied pressure between the outer sleeve and inner cable.
Don't know if still available.

Small U-Bolt should do the same.

See other current post
Treat it nice
See if there is a friction device on engine
Don’t be tempted to open it detent spring Is specifically designed to move like a winch handle in flight

From memory, there is a flat spring- loaded pawl that puts pressure on the main wheel assembly.
Maybe the spring is just a bit tired

Yes. In MT control but not in this unit

OK ...

I was thinking whether to get some thick string or rubber to wind between the lever and the body ..

I was hoping that the 'button' on top was something to do with this - but its only a spring housing for the ball detente.

At the engine end is there a spring you could adjust, a lever you could change the effective length of, or angle of pull of the lever and/or cable you could adjust.

Alternatively, you could advertise in the Wanted forum for someone else's old, seized stiff Morse cable they were replacing!

I tried looking at the carb end of the cable - it terminates underneath the front one of the three huge carbs ..

Difficult to see ...

Here's a picture taken by holding phone down there ...

Here's the carbs hiding the assembly !!

Isn't it always something like that?

I would be looking at the carburettor linkage for a solution

. . . if set at a low to mid range throttle lets say 1500 to 3000 rpm - the lever slowly moves back to idle .. if I set at higher - lets say 4000+ - the lever tends to stay where put.

You just need to go faster then!

At mid range - 10ltrs / hr ........ at max = 0ver 25ltrs / hr .....

Yep ... and dreading taking that great big air intake off ... whoever created the engine bay - left it at rear over the intake body - so its a real pain to remove ..... there must be about 1 micron gap !!

Small U-Bolt should do the same.

The type I have seen just had a single clamping bolt

Used to be able to get in bike shops I think

Cable clamp seems a bit 'agricultural' .... but if that's the way - then that's it.
