We have a Johnson 3.5 two stroke for a spare dinghy motor
. Nasty little thing -- noisy, vibrates like hell, uses too much fuel
, etc, but it was reliable for many years. Then one day it refused to start. investigation shows zero spark. Did the usual checks, and was left with the thought that either the coil or the CD unit itself has died. Don't have any friends with similar motors to swap parts
with, dpn't want to start buying
bits at random. It's a bit embarrassing to admit but I don't know how to effectively determine which part is at fault, so I would appreciate any wisdom from the crowd.
