Mcculloch ?

Have a 3216 mac I was given years ago replaced fuel lines and rebuilt carb. This was 3 years ago I did the carb and lines well it will start for a few seconds and die took carb apart and diaphragm looks good screen is clear fuel pump is the new plastic type it looks good no obvious signs of air leaks, short of buying a mytivac and pressure checking the saw and carb what else can I check fuel lines are still good and carb adjustments tried a turn and half and two turns any ideas would be apreciated.

it's spelled mcculloch,

is the fuel filter clear?
dose the primer bulb have cracks?

Sorry about the misspelling the fuel filter is clear and I bypassed the primer bulb, its just a cheap saw just irritates me when I cant figure something out and thanks for the ideas.

To many gas fumes has compromised my spelling.

it's all good, i can't even spell..
you need the primer bulb it acts like a one way valve. try just blocking off the return line

Will try that thanks I need another length of hose to rehook the primer bulb, will try that blocking it off in for now. Thanks
