The mush button for the gas is the primer. Try it x2 pushes, instead

It would NEVER start with just 2x. The owners manual says to use 6x; the
bulb has a 6x embossed just below it; and the complex starting instructions
on the sticker on the side say 6x. Even when new, it barely started with
6x. It took more like 8x to 10x.

Dunno if it's a California thing or not but it just never ran well.

From what people say, I either need to mess with the screws on the carb or
I need to find why (if) it doesn't have spark.

I can easily mess with the screws (after finding the procedure somewhere)
... but how do I tell if it doesn't have spark?


As far as the run and idle screws...I start at 1 to 1.25 turns backed-
out. The carbs on new stuff is pretty much crap these days.
