Overall, I like it but there is one small issue. If you stop on a steep incline, you may not be able to continue up the hill without backing down and getting a running start. That happened to me early on when I was driving around on some back roads in the Santa Cruz mountains. I never experienced that problem with the factory flywheel.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>John<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b>From:</b> Healeys <healeys-bounces@autox.team.net> <b>On Behalf Of </b>Bob Spidell<br><b>Sent:</b> Thursday, June 20, 2024 7:30 AM<br><b>To:</b> healeys@autox.team.net<br><b>Subject:</b> Re: [Healeys] Healeys Digest, Vol 17, Issue 98<o:p></o:p></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal style='margin-bottom:12.0pt'>Thanks for the input Craig.

My BN1 has one from DW that weighs about 12 pounds and I'm using DW's damper on the front. The car has an upgraded crankshaft and BN7 gearbox, so maybe that's kept it from flying apart. My BN7 w/BJ8 cam has an alloy flywheel I got on eBay that I think weighs about 20 pounds. It runs smooth as silk with no ill effects. I still can get occasional run-on though, with lower octane fuel. <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:18.0pt'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span style='font-size:18.0pt'>On the gearbox oil leaks, check the lower bell housing bolts which, at least on the side shifts, extend into the gearbox and can leak. Also, "Quad Ring" OD operating shaft seals are available from AH Spares, part 0VD185MS. I haven't tried them yet, but it seems like they would be an improvement over the single O rings generally used. <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:Roboto;color:#2E2E2E'>OVD185MS</span><span style='font-size:18.0pt'><o:p></o:p></span></p></div></div></blockquote><p class=MsoNormal><o:p> </o:p></p></div></body></html>
