Hi all..Just joined forum to hopefully get some advise.I have an old Oleo Mac 251 saw which up to now has been ok.I have the following problem...
A vacuum is being formed in the fuel tank and I cannot understand the tank breather arrangement.The tank has a solid cap.On the top of the tank is a diamond shaped bolt on unit which takes connections to (a)underside of it to fuel pipe/filter inside of tank and (b)on top one tube connection to the carberetta and another to the outside.
Has anybody a clue on what should happen.
Thanks in advance

Ps. is it pos to upload pics?
