hi guys,
heres the torque values for a mc motor as set forth by Mike Savin in his booklet "Speed Secrets and Tuning Tips"
torque values
Coil/lamination Screws ------------55-60 inch pounds
Condenser screws ----------------30-35 inch pounds
Con rod - mc49 mc 91 -------------105-110 inch pounds *
Con rod - mc101 ---------------90-95 inch pounds *
*torquing to 110 possibly could result in a cracked caps.i myself do 85-90 inch pounds
Crankcase End Cover Screws --------60-65 inch pounds
Crankcase Bottom screws -------- --95-100 inch pounds
Cylinder Head Screws -------- --55-60 inch pounds
Exhaust Header Screws -------- ----55-60 inch pounds
Fan Housing Screws ----------------55-60 inch pounds
Flywheel nut ----------------------300-360 inch pounds
Spark plug -----------------------216-264 inch pounds
Clutch Nut ------------------------ 260-300 inch pounds
Bonus info:
the following piston to cylinder clearances are recommended
mc49 series .0045 to .0055 inches
mc91 series .0065 to .0075 inches
mc101 series .0070 to .0100 inches

coil gap .018" and points .018" to start with before timing is set. Make sure your timing light is firing when the timing mark on your flywheel hits the front side of the magnet going from left to right. This will give you a good spark and ensure your timing is not advanced to far.
To test your condensor you can take a multimeter set on ohm's to charge your condensor (capacitor) by placing the negative lead on the mounting screw and the positive lead of the multimeter on your condensor lead while it is not hooked up. You should be seeing your meter take incremental readings until it over loads. Quickly switch back to voltage DC and watch your voltage drop back to zero. This will give you an indication if your condensor is still good.
