is there a TON of compression? will it kick back on the starter hard enough to break the housing? i mean , that's pretty thick aluminum....

does the motor have any vibrations? could the fw be bent?

other than that man, i'd almost want to blame it on a manuf. defect in the starter. if everything came from one ford to another - it should all work the same

No vibrations, 2nd flywheel...

It broke the XS start by the adjusting bolts. Worked fine before than. 12 to 1 comp, seems to spin fine but does have some kick back. Think a shim would help?

thats what i was thinking

Talked to a bunch of people this mornng...

Lots of people have had issues with the JW Ultra Bell and starters...

Anyone using a JW Ultra Bell, What starter are you using??

HatefulMechanic

what kind of timing are you running? i've broke the shit out of some on BBC's with a fixed advance dist. having too much advance on start. a crank retarder was needed to fix that one.

Also may want to try asking on VaMustangEnthusiast there's been a huge influx of guys with fast cars on there lately

ICULOKN

35 Deg locked out.... But I do have a 10 deg start retard on it...

i don't think a shim would help in this instance UNLESS maybe the starter were too deep beyond the flywheel when the gear extends, and maybe hangs up behind the ring gear when the motor's running ???

but hell, for the cost of a shim vs. cost of a starter - why not

my father in law has had the same issue on his truck to come to find out it was the wrong starter for the fly wheel I think his was a 162teeth flywheel and he was using the starter for the 157 teeth flywheel

Index the starter or as stated(shim) been thru this with every car I've had when using an other than stock bell or tranny
