OK , so here's what I got . I have an older 18" Poulan Wild Thing chainsaw
.. It has an angle plate between the carb and cylinder , it's apparent
purpose is to angle the carb up slightly . Problem area is where the plate
bolts to the cylinder . I can't keep the damn screws tight , and when they
loosen the saw just doesn't run because it's a massive vacuum leak . I've
tried red loctite , tried dry , and they just keep getting loose . Carb to
plate screws are fine , no problems there .
Fortunately I have 2 other FREE ! saws , so I can still cut firewood ,
but I'd like to get this one reliable , as it has the longest bar . Cuttin'
fool when it runs right , as are the others since I learned how to sharpen
chains . Very important tool if you heat with wood !

About those free saws ... both needed work , PO's couldn't get them to run
right . Both have new chains now , 14" Homelite also has a new sprocket .
16" Stihl needed carb cleaned more than anything , though it still has
isolation mount issues .
