The magneto is completely independent of the rest of the electrical system – be assured it’s condition cannot affect cranking speed whatsoever!

With that said, a “slow crank” condition can only be caused by the following: 1 - Weak, partially discharged or undersized battery. 2 - Excessive resistance in the power circuit (undersized cables, corroded terminals, worn starter switch), or 3 – A weak starter.

#1 and #2 are pretty easy to diagnose and correct. #3 however may be more difficult.

If you are so inclined, open the starter up and check for a broken or stuck brush, a bad solder connection where the power terminal connects to the field winding straps (this connection fails frequently…), or an open circuit in one of the field windings.

Otherwise take the starter to a different starter shop. (Could be the first shop “tested” the starter simply by applying power to it on the bench - it can spin fine under no load but still be weak).

Another way to test the starter: If you can borrow a starter off another C (or an A, H or M), install it temporarily on your C and see if the cranking problem goes away.

Hope something here helps!
