Hi all,
I just finished up with some ignition systems upgrades. Compufire points replacement, and Tiger CDI. Sticking with the Bosch blue coil as there does not seem to be any reason I can find to change it. I pulled the plugs to open the gaps to the recommended .040''. The Wonderbus now starts instantly.
A couple of questions.
This is a new Mexi long block 1600 DP. The plugs that came with it are long-reach NGK BP5ES-A. I should pick up a spare set of something good. Anyone have a strong recommendation?
Also, I noticed that #4's plug had some chalky powder on it. #1 had some powdery soot. #3 and #2 were smooth, light-brown. I run California's 87 octane [(R+M)/2] Mystery Gasoline. Normal variations?
