Ordered a new cam today for the W2 408

I dont get any bucking.
246/250 on a 108 and a 20lb Mcleod flywheel . 3.55 gears and an 833 with normal first ... not 3.09.
That is good news, I was getting a little bit at very slow speeds with 3.23 and 3.09 first. I thought my flywheel was 18lbs by memory, but it has been a while since I looked, could be 20. Might also be the 23 degrees initial timing. Also changing to 3.73 gears.
