Our BN2 has =E2=80=9CM=E2=80=9D mods using a different cam grind then the f=
actory M grind (Delta Cams) and 10:1 compression. The stock head compressio=
n chamber was cleaned up a bit and the ports slightly smoothed. I had to fi=
nd the right carb needles to make the rev range smoother and to provide con=
sistent performance. Took a bit of trail and error. Also had to play with t=
he static timing but did not have to re curve the distributor. I run a few =
more degrees than stock but that has a lot to due with the cam grind. =C2=
=A0Suspect that if the spark plugs fire at 0 RPM to 2500 and from 3200 up, =
its probably not a plug or distributor problem. The variable is the control=
 of fuel and the mentioned potential problem areas (needles, damper springs=
 and oil in the pots) have a lot to due with controlling the mixture.=20
