You gotta love spell correct! The subject should read, “028 Hard to Cold Start”. (I can’t find a way to edit the subject line.) Is this possible?
It looks like the butterfly on the carb is very slightly opened when in the choke position. Once the master control is moved to the run position the butterfly closes completely. Recently had the chainsaw disassembled and the engine passed vacuum/pressure test, that included both the intake manifole and the impulse line. I think I know the problem.
On cold start when my wife plugs the carb throat with her finger it pops right away.
Also (another issue that may be related), once the engine pops and the control is set to the run position, it is much easier to start if I tilt my foot in the handle to move the throttle level to full speed.
Is it possible the small black plastic rod that is controlled by the master control is bad?
