It seems all weedwacker motors are hard to start and a primer button sure
helps.
It sounds like you might have some varnish build-up inside your carb as
well. If the machine sat for the last year with gas in the carb it probably
fouled inside. 1 year old gas also causes problems in these smaller motors
(I just went through this with a small Stihl powersaw).
If your needle adjustments don't give you a fix then take off the carb and
clean the inside and the jets and fill it with fresh gas.
