Yes, Choke knob.. Spell checker got me again. Have an engine sitting waiting to be installed. .90 over, aluminum big valve head, Piper fast road cam, flat side crank and later rods with the balance pads. Haven't decided on the carbs, (something else not well understood anymore) Have the 1 1/2" SU's, 1 3/4" SU's and a DCOE. Also found a Mallory dual point distributor, but don't really see that as an advantage on a 4 banger. Might make 130HP, but in the light weight MBG it should be interesting.
