No idle

[Roxylass]

Coming back to the mooring today put the revs right down almost idle sr2stopped

started first turn when I was going out ignition light went out touch of revs

probally a two hour run didn’t go above half throttle 

carry an aux but still like to know why engine cut out at idle

Is the oil level going up and does the oil feel thin & smell of diesel?

 

All those air cooled Listers have a nasty habit of leaking fuel into their oil and that can cause partial seizure that causes the engine to stop when it drops to tickover.

Hi Tony

Oil pressure never moved at all

No smell out of the ordinary

Oil still shows clean on the dipstick

Couple of minutes to tie the mooring lines on turned the key started no problem

If it keeps doing it see what happens if you try it with the fuel filler cap off.

Are your air ducts present/connected and clear.

My old one used to do that when it got a bit warm..

Aah well-thought Id try the cheapest possibility first .

The next time I came across this problem the engine actually had no oil in it. That was several years ago and as far as I know the owner is still happily chugging about with it ? Robust engines them..
