EXHAUST MANIFOLD ISSUE
in 2 Stroke Technical Questions
13 years ago
On my 618 today I got 750F on the one cylinder and 130F on the other one, All these on the runup.
I went back to the hangar and switched the sensors, I did another runup This time the same thing happen but in reverse, I think that issue can be solved with 2 new sending units.
But I also notice oil spiting out of the 2 ends of the elbow connector that connects the mafler to the manifold, I notice this as well on the 1st runup but the amount of oil spited out from the 2 ends had been doubled on the 2nd runup,
I also my full throtle only give me 3400RPM whch is about 1/2 of what it supposed to be.
Is there a posibility for one of the cylinders not to run?
I suspect that The RPM issue can be a PROP pitch issue as it is a new prop, Although a got me 6800 rpm on my static test but before I start with the prop I want to fix the manifold issue first.
Any assistance advise or idea wil be apreciated, I did attach a picturer showing the elbow connector and the oil on the mafler.
