Carb Question
Hello,
I have a used magnum 40 engine with out a manual.I am trying to get it tuned and its really out of whack.
After reading some other threads here at rcu Im convident I get it running.
The question I have is about the 2 screws on the carb.When looking at the engine from the front,the needle valves on the right.
On the left of the carb there is a screw that is inline with the needle.(I asume this is the idle screw).
Behind that is a screw that come straight up.Im not sure what this adjusts.
any help would be appreciated.
Thanks, Scott
