OK, but how does he know this is where the leak is? when i do a pressure/vac test i slacken the carb screws, place a rubber wedge between the carb and inlet boot, re tighten the carb screws.

 

Good point well made Andrew .

Put some instant gasket round it then put it back together and clamp it up.

 

Did think of that but dont want to block the impulse hole too. It would be difficult not to if i put that on.

the flange is 503 92 85-02 at a price of £2.36 + vat

 

the intake boot is 503 92 87-02 £ 11.02 +vat

The boot may be split and you cant see it untill you pull it and stretch it this wasy and that . Try a new boot .

 

Put a new boot on, didnt help. It was first thing i tried.

Didn't split it with the screw driver ...possibly ?

Just a question, how do you know its leaking?

 

When its assembled and running, which is difficult to keep running, i carefully spray a bit of cleaner at the joint and the saw revs its nuts off.

Thought it was the carb at fault? Least it was that you were blaming last week! :lol:

 

Carb replacement was needed to discount that as the issue, gaskets were very poor, carb full of bits and h n l screws looked like someone has driven them in with a sledge hammer. For the price of the carb it wasnt worth not replacing to make the saw good again, or at least try to.

Not doing pressure test just testing with spray around the joints.
