I will be trying one of those on my beloved hotel when I next get the opportunity to play with it. Fingers crossed the stem seals cure it. I doubt it, though.

I did a little impromptu work on the KP tonight, and finished the grill mounting improvements: https://twitter.com/FredCookeNZ/status/ ... 5972276227

And noted that it's still an utter failure, living up to its name: https://twitter.com/FredCookeNZ/status/ ... 4351674368

Moved her back against the engines and BBQ, too, so there's a bunch more room at the front of the garage for GP use. Including getting her half out to work on the back of her.

Tonight the second 4age got chained up and hoisted up into the air. This is how it looked: https://twitter.com/FredCookeNZ/status/ ... 8622990337

I suspect a bad bottom end in this engine, so I need to get the sump off and verify that I'm right, or wrong, and make plans accordingly. If the bearings are fully gone/spun/loose, the head will be damaged, too. Hopefully not, but...

The crank in this engine is damaged anyway, on the outside, the nose has been ground/mangled away. So I'll need a new crank from some other similar 4age (only two crank types) to make it right again.

Tomorrow I'll whip the sump off and try to figure out what the story is. Fingers crossed! Expecting the worst, hoping for the best.

Sump and windage tray are off. Looks OK. Fairly clean and though I can move the rods along the crank slightly (normal play), I can't get any slop out of them in any other direction! Good news! A couple of pics of it:

Windage: https://twitter.com/FredCookeNZ/status/ ... 2916994048
Crank/rods: https://twitter.com/FredCookeNZ/status/ ... 4147767296

Next steps:

1) Find new crank, probably from a silvertop
2) Find sprocket and disk, definitely from a blacktop, or use the ones from the smoky blacktop
3) Pull rear main and oil pump off
4) Install with new bearings/gaskets as required
5) Find a bell housing and run it up on the bench :-D
6) Install in Starlet :-)
7) Lose license :-p

Dreams are free. Unlikely to progress beyond this point anytime soon, sadly.

Cunning plan for a trigger signal and code combination documented in my mind, jogged here:

Brought home the new wheels for this tonight, nice and light, just the wrong offset, so I can't try them out until I can afford some spacers. What I do have, though, is some tyres that are close enough to correct to work for test fitting and a bit of a play. They're basically ruined 205/50R15 R888s that some BMW owner destroyed. I paid too much for them a while back (80 bucks for the 4, no big deal) and thought "I'll chuck them on something at some point" and this is it. In inches, rolling diameter for the 205/50R15 is 23.1, just a hair bigger than the 22.6 of the current 13" piles of junk. I can re-evaluate what I want once I'm up and running scuffing the last rubber off of the worn out R888s. References:

https://tiresize.com/tiresizes/195-50R15.htm 22.7 < super close.

Re those rolling diameter numbers, here's a KP60 on 15s with 175/65R15 tyres, which have a diameter of 24.0 inches, significantly bigger than stock:

It is lowered on "super low" springs, though, which helps make them tuck in and not look bulgy.

I don't think it looks out of place on 15s, personally. Many KP and AE fans prefer 14s, but to do that you have to suffer on brakes. Speaking of which, I should revisit the brake measurement situation now that the new wheels are in hand. Ref: viewtopic.php?p=41545#p41545

The thickness of that outer piece is about 25mm, and a further 4mm to the edge of the pad, which we'll split in 2 for clearance, and call 27mm, implying a correct rotor diameter of 282mm. Obviously it'd be OK to go a bit bigger or a bit smaller than these figures, and my measurements could be a little out anyway, but looking at the wheels I have on hand: https://twitter.com/FredCookeNZ/status/ ... 7748806656
https://twitter.com/FredCookeNZ/status/ ... 6817507328

Looks like I have a comfortable 325mm to work with, probably more as we get away from the flange and further into the centre of the vehicle. I have no idea what's possible/reasonable in that respect at this point, but will need to find out before choosing rotors. Pessimistically, though, 325 is 11mm under my ideal for the calipers, so I'm 11mm under the ideal rotors, so my rotors should be max 270-272mm. I think the Lantis ones are 274mm, so they're no good. Might run something with alloy hats like I will on the truck, anyway. Then I can pick and choose the position to suit myself. That should also mean that I don't even have to machine the stock hubs. I will need longer studs in there, though, and I'll need to do that to the rear end, too, in order to fit these wheels up and try them out on the street :-)

In other news, the second 4age is tucked in the corner to the right of where you see it hanging in this shot: https://twitter.com/FredCookeNZ/status/ ... 4053237760

viewtopic.php?p=41577#p41577

I've been doing some more research on this topic and have decided that I don't like where the handbrake is, either.

135mm from dash to knob centre in third. My arm at full extension, dead straight.
255mm from dash to knob centre in fourth. My natural position for neutral.
70mm further back than current fourth, my rear most position, elbow touching seat.
Steering wheel is roughly 50 to 100 mm further back than the shifter in neutral.

Arm also fully extended and dead straight to handbrake handle in down position.
20-50mm further back would work well for me.

200mm from shifter centre at floor to tip of handbrake handle. Is this what I said above? Sort of.

Shifter is angled back pretty heavily to be even vaguely comfortable, as it is.

Sampling five vehicles, three manual, four with proper handbrakes, I found that the Starlet handbrake could go back as much as 80mm to be where the other three are, and that the other two manuals put fourth gear in the most comfortable rearward position, with neutral just forward of there, and third being maybe 80mm before the extent of my reach.

Reading through that, new fourth should be 70mm further back than old fourth, and old fourth is 200 further back than the hole centre, and new fourth is 70 behind the new hole, meaning that the new hole should be exactly where the handbrake handle tip is now, and the handbrake should go back enough to be clear of the new shifter in neutral.

I think. A couple of pics/tweets:

EDIT in morning. Too tired now.
