Dragged out the chain saw and fuel lines fell apart, can't tell where lines originally went.
The way I have it is, from fuel filter pickup into top fitting on carb, out of bottom fitting on carb to short nipple on prime bulb, then from long nipple on primer bulb back into Tank, The way I understand it, is the Primer sucks fuel through the Carb, and not Pump into Carb.
Manufacturers site does not show fuel routing and no one answers the phone.
Thanks

Hi,
I will give a link and we can go from there; be a bit patient as there have been ownership changes with McCulloch right and left in the last decade or so.
Free McCulloch owners manuals, user guides & how to instructions | ManualsOnline (http://lawnandgarden.manualsonline.com/manuals/mfg/mcculloch/)
And try the MS1635
Peace,
Clarke

Hey Thanks, I had found the User Manual with the Exploded diagram, did not show Fuel Line Connections, just straight pieces of tubing.
I had also checked their site, calling them got no answer.
Hopefully someone else will provide additional info, thanks.
