Well...I assambled the chainsaw today. Oil pump to. Cleaned
ewerything to perfection...still got no oil on the chain bar and
chain.
Something strange happens all the time. On the oil cap
side,bellow the exhaust, there is a small bleed hole wich serves
as air inlet hole as oil is getting used and dissapears. On that
werry hole when I press full trottle oil is comming out it
bublles if oil tank is full... Buth on the chain side a hole
which should be draining oil hotthing happens. No oil.
Checked all holes, cleaned them. Made new gaskets. Tryed
ewerything. And no oil on chain. :(
Please help, i am getting disenchanted totally
EDIT:
Here are few oil pump pictures beffore cleaning:

take the pump off and soak it in some kerosene for a few days.
the check valves are gummed up. and you can't take them out for
service.
another thing to try is in a container big enough, submerse the
pump housing with the piston/spring instaled and tap the piston
in/out very fast and firm. unscrew the limiting screw to add
some more stroke to the piston. gawd sounds dirtay :D
you'll notice when the little check valves come loose. lift it
out of the kerosene (or diesel) and give the piston a few pumps.
you should see the level in the intake port go down. and the
output port go up. keep doing this for a while, then switch over
to a light oil. should clear the oiler out so it works again.

the little check valves in the pump housing are still stuck. if
you're seeing 'pressure', or bubling oil coming out of the tank
vent, it's because the checkvalves are stuck. i'm talking about
the small spring and ball type in the pump housing that you
can't get at as they are permenantly assembled. you need to get
them unstuck. try as i posted using the red piston/spring. you
need to be pretty vigorus moving that piston in/out until they
free up. you don't have the pump cleaned perfectly until it
pumps oil. after that it'll take about a minute or 2 until you
get bar oil to the bar.

so majhne preverite ventili na ohišju črpalke, so še vedno
zaljubljen. če ste videli "pritisk", ali bubling olje
prihaja iz rezervoarja vent, je to zato, ker so obtičali v
checkvalves. Govorim o malih črkah spomladi in žogo v
ohišju črpalke, da ne morete priti v kolikor so permenantly
sestavljeno. jih morate dobiti odlijepio. poskusite kot sem
objavil z rdečo bat / pomlad. morate biti lepa vigorus
gibljivi, da je bat in / out, dokler ne sprostite. nimate
črpalka očiščena odlično, dokler se ne
črpa olje. Po tem bo trajalo približno minuto ali 2, dokler
ne prideš bar olja v bar.

musíte si ich rozlepený. sa snažil, ako som vyslaný pomocou

nemáte čerpadlo vyčistiť perfektne, kým
čerpadla oleja. potom, čo to bude trvať o minútu
alebo 2, kým sa nedostanete bar olej do baru.
