    Those weren't oil leaks. They were an anti-corrosion treatment for the underside of the car. Worked fairly well, thought the coverage didn't reach the sills so they tended to rot if you didn't manually apply oil.

    Sorry, nothing personal. I have to ask everyone. Someday I'll find the guy, after these years of searching, then it will be like the ending of Boy Named Sue.

    The new thread is a builder's log, so only TiPi can post there. It is his own account of his particular build, and he's using it to give info on his decision process as well as the actual build. The builder's log format keeps thing on track.
    We could start a separate 810 only regular thread, but there's already a lot of stuff here and it's mostly 810 already, so I'd say it may be better to stick with this one. But, I'm flexible.

    Why couldn't the PTO end be tapered to eliminate the keyway and a portion of the propeller flange ride on the bearing support?

    I figured I was playing left field without a glove again.... thanks for the explanation, my computer skills are that of typical 74yr old. Good thing I have grandkids.

    IIRC, the tapered crank comes on their generator version of the engine, set up for propane/natural gas. It will be interesting to see about availability/cost. If there are no problems there, it would be an attractive approach.

    Instead of retaining flange with one bolt couldn't it be retained by two or three bolts offset from center and "not" evenly spaced, for indexing?

    I'm no expert, but:
    - if there's an off the shelf hub available, it has one hole.
    - more holes = more stock removed= less crank remaining (this is opposite of the direction we want to go). Plus, holes closer to the edge are even worse for raising stress in the remaining material when subjected to bending or torsion.
    -Indexing of the prop can be done at the prop/hub interface. That's more useful, since the prop can be expected to be removed there more often, and it is the prop's position that is/may be significant. IOW, there's no point in indexing the hub if the prop will be removed from it semi-routinelly.
    Just my thoughts.

    Was thinking the bolts can be pretty small and basically inside or close to the periphery dia. of the stock bolt, additionally the PTO end is larger dia.. Also transferring the gizmo's attached to the now discarded flywheel will like to be indexed rather than dialed in each time hub is removed. But a different way to index is probably wiser. I just don't like the keyway and looking for an alternative. The following may be to expensive but is maybe best? https://patents.google.com/patent/US20020164252A1/en

    Maybe he's related to that guy who did the British motorcycle electronics of the sixties, you know, Lucas the "Prince of Darkness".

    measured it this morning, got 3bar (42psi) cranking with the drill on slow speed. So possibly 3.5bar running which is the upper limit of the B&S specs.

    Maybe it's all that warm beer you keep spilling and scaring the electrons? I never had any trouble with my Lucas - MG, Austin, Sprite or Mini. Now the SUs in the winter o_O
    Named one all white cat Lucas. :cool:

    I still remember the time when I was 18 and cornering hard in my sisters Mini on a moonless night...
    I had already learnt to carry a spare light switch for mine and replace it at the first glitch. My sister was behind the curve on that...
    I had a single SU glitch in all my Leyland years. The piston got hung up after a run on my Moggy Minor. I had a spare, so swapped it.

    I escaped much of the electrical trouble, just one behind the dashboard, er, fascia fire in an XKE and iffy headlights on a Spitfire. But the oil and hydraulic seals! That's why I thought of it when I saw blane.c's sketch: build a fiddly, trouble-prone thing and put it in a hard to reach spot. So, leaky rear disc brakes, and place 'em inboard so the rear end has to be dropped to work on them.
    Still, I miss the cars. It's a bit like visiting Italy--nothing works like it should, but you still look back on it fondly.
