    Mark, what do you suppose I might find causing it not to work? I've actually never had a manual oiler not work. I'm thinking it.must he the check valve not working.

    It's possible that your check valve is gummed up with old oil that gets almost like gel.That's why I think some type of penetrant in there to help dissolve that crud.

    Most SDC do have the check valve diaphragm in them. Attached is a list of SDC carbs (I think a few are missing). Find your carb model number on the list and look to see if #25 check valve diaphragm is listed or if there's just a dash in there. If there's a dash instead of a part number the check valve diaphragm is not needed.

    Tim,I've looked over the SDC that I rebuilt yesterday from top to bottom & I can't find the model # anywhere.That carb had the two pump diaphragms in it when I took it apart,so that's the way it went back together.It won't do much good to put it back on the saw just yet,I need a new fuel,I should get it by the end of the week.

    And new rubber goods in the carb. Darn Zama!

    One more 125 question.

    This cylinder seems to have a fix on the clutch side. There is the much love JB Weld goop with a plate. Looking inside I'm not seeing any cracks.

    So...is this a fix or a reinforcement?

    This cylinder is about to be sent out to be bored out and want to make sure it isn't junk.

    Do not send it with the nut retainers or anything else that will come off or they will not come back. Brian

    Did anyone watch Pawnstars tonight? They toured Ronald Reagan's ranch. At one point they toured his garage/shop. You can see on the shelf 4 McCulloch chainsaws.

    He could have had one of the SS guys sharpen his chain.
