Hello gents,
the coil/flywheel from the 11ci vertical pull quantum wont work, it's the same size as a 9ci motor(450 series, classic 35, sprint 375 etc.)
You will need a coil from a 12ci quantum, I've got heaps of them here, but postage may hurt a little getting it to you.
The tecumseh coil i've never tried but probably wont fit either
Cheers, Ted
