Hello forum.
Maurice.
Have a Yamaha 3.5AC 2stroke aircouled .
Full cleand caburature . fuel lines filter tank.
New plug. ect.
Also blow throug the valve on the cilinder.
Some kind of compressionvalve?
First pull runs smouth and perfect.
Full power ok till about 15min. Than stalling.
Pull out the choke first pull running. But
no running when I push in the choke.
So can run for 3 min on choke out a bit.
Than It sounds after 3 min better and I can push in
the choke and it runs again Full power
perfect.
Then 5 min again stalls pull out choke 3 min. in
again full power.
I allready adjust the fuel level floting.
Have 4times cleand the cabb now and with airpresure
blown all the nozzels.
Some timer in that engin that suddenly
with in seconds stall that engin.
Its no ignition I think . First pull it runs quite and smouth
every time.Also after stalling. it runs in 1 second with choke out.
Also take off the fuelcap. There is already extra
fuelfilter installed.
Can.t figure out this problem.
