Henry,
Thanks for the offer. This morning for comparison I measured a TR3 engine I
have on my own floor and pulled an old starter. Since the starter pinion
gears come at the flywheel from opposite directions I measured the edge of
the gear closest to the block in the engaged position from the block/starter
bolt-up surface on the starter. Then I measured the back edge of the ring
gear from the same location on the blocks. Everything except for my Hi-Tech
starter measured in the 1.066 to 1.099 range. The Hi-Tech starter measures
only .857 and, and it's a big and, the wear pattern on the gear shows only
half ring gear engagement. With the new flywheel it's not quite reaching the
ring gear. I think I had an incorrect starter in my TR4 and it worked at
half engagement. I'd bolt up an aluminum flywheel and measure that but I
used the ring gear. I'd love to know the specs for the non-bolt on ring
gear, but I still need a trustworthy starter. I'm going to order a correct
starter and I bet it works.

Bob,
I am unfamiliar with that flywheel but your synopsis sure sounds right,
I would suspect the flywheel is the problem. I have a stock TR3B engine
with the flywheel installed on my shop floor. No gearbox is attached. If
you would like a measurement or two feel free to ask. Should be able to
get to it tomorrow (Sunday) and get right back to you.

Subject: [FOT] BPNW lightened steel flywheel
Has anyone used a TR4A lightened steel flywheel as sold by BPNW? I have
one in the new TR4A. I had to use a TR6 slave with a shortened TR4A
pushrod to get the throw correct and today I installed the spare hi-tech
starter that fit in my TR4 and it doesn't engage. I'm not sure what the
differences are between the early and late hi tech starters. Do they
have a larger gear? I'm suspicious that the flywheel is the problem
because of the slave issue. I have the later style clutch and the
flywheel uses the bolt on ring gear from the later TR4 version.
