Redline's what I use in everything... off road bikes and power equipment.
The aircooled oil is designed to work in a hotter engine
without leaving too many deposits but any quality synthetic will do
fine... this isn't a highly tuned motor.

The pump is a diaphram on one side of the carb.
That side of the carb will have a vacuum line to the crankcases.
Case vacuum moves the diaphram, which pumps gas
into the bore of the carb.

Sometimes that's a symptom of a fouled plug.
Happened to my weed whacker a couple weeks ago. In a pinch you
can ressurect a plug by spraying it with carb cleaner and
using a propane torch to burn off the carb cleaner.
A short spritz of carb cleaner in the cylinder before you
put in the plug (after letting it cool) will act as
But of course a new plug is better.
