The chainsaw is not oiling the bar. No oil out of the oil outlet gromet.
The oil gromet (14) is clear. The oil tank filter and line (15 & 26) up to the outlet gromet are clean/clear.
Just above the screw in oiler resevoir cap is a brass filter element. Behind it is a duckbill. I think the problem may be there. Either the brass element (12) is pugged or the duck bill (13) is not working.
The plug goes into a hole which runs to a 1/2 inch or so tube molded into the inside of the case. I am not sure how the duckbill fits in. Either it goes through the outside hole followed by the brass filter or put in from the inside over the short pipe. When I look in with a mirror I can just see something white up in the hole which may be the duckbill. If it is then it must have been installed from the outside.
I assume the pressure for the tank comes throught the duckbill but not sure how pressure gets there. It might be the filter allows air in which might be sourced from the flywheel fins. It might also be sourced by a hole near the filter and air routed from somplace throgh the case to the filter. ?? Not sure.
The questions are:
1. How does air get to the duckbill.
2. How does the brass element come out?
I used a bent coathanger to try pushing out the brass element from the inside but realized there was something squishey in there and probably the duckbill.
17 - outlet gromet
19 - Oil intake tube. The filter goes on the bottom end (not the brass element filter).
16 - Called a oil pump kit. It's just a plastic part with a tube on each side of the standoff. One is for the oil tube, the other accepts the outlet gromet.
15 - Oil outlet tube (same as 19 above)
14 - Oil outlet gromet.
26 - Oil intake filter (not the brass element filter).
12 - Brass element filter.
13 - Duckbill.
