Help,
I've hit a brick wall in installing the fuel tank vent. :bang:
Following instructions in a downloaded manual(see below),
I removed the old vent. (It was was leaving a puddle of fuel if the saw was clutch side down.)
Figured it would be fairly straight forward to install new one. Looks like it should be a taper fit and used a drift to try to seat it.
No matter what I do, I can't seem to get it to seat tightly.
I've knocked the drift with a hammer and it feels solid,
but if I put my finger in the fuel tank, I can push the vent out with very little pressure. Surely the vent will fall out when the tank vibrates while running.
It took some effort to remove the old one.
I even took an exacto knife and tapered the shoulders on each of the two connections of the three size 'tubes?' that make up the breather body, thinking the shoulders where too square and hanging up on the shoulders molded in the tank body.
Now that I think of it, the only thing I haven't done is clamp on to the vent tube from inside the tank and really pull on it. I did pull lightly trying to line up the shoulders, but didn't really put effort to pulling for fear of ruining the new vent.
From the manual:
Disassembly
The fuel tank vent is located on the right side of the fuel
tank next to the right rear rubber element. With the fuel
tank empty and the fuel hose disconnected at the
carburetor, remove the two rear rubber elements as
described in section 9. Anti-Vibration System. Separate
the rear of the crankcase and the fuel tank enough to
expose the fuel tank vent.
Working through the fuel filler opening, grasp the fuel
tank vent tube with a pair of needle nose pliers. Push the
vent out the other side.
Assembly
Install the fuel tank vent using a drift the same diameter
as the vent tube. The remainder of assembly is the
reverse of disassembly
