I flippin’ hate modern mowers. Over-priced, under-built tat (unless you have a really expensive professional one), now with all kinds of interlocks that stop things happening. My concern with the reverse polarity incident is that you may well have fried the PMC module, so effectively your interlock circuit is broken and locking everything else out.
I should emphasise that this is a guess based on this being the only thing likely to contain semiconductors sensitive to polarity. I suppose it’s possible alternator diodes beefier be damaged too (though these are beefier devices).
Good luck….

Your considered, methodical, patient approach is an example to us all!
The god of unforeseen consequences lies in wait for all we modifiers, licking his lips and waiting his chance to pounce. He certainly has a ball with me, but I don’t reckon he gets much luck with you…..
Keep up the excellent work!

I would have thought in that age range the immobiliser is the main issue.
The factory Honda ECUs of that era were regarded as quite “hackable” and got transferred to other cars as a result. There were a couple of quite good forums covering it, dunno if they still exist. I didn’t go that far with the idea as I needed 6 cylinder coverage

Not blocked jet as one carb feeds all and SUs don’t really block. Are you running this with choke, does the misfire start when you put the choke in? Does pulling the choke out help? Does the misfire go as the revs are increased?
If yes to above, possibly inlet manifold air leak, perhaps at the head face (could affect two cylinders more than the other two because shared ports.
Beyond that, new unfortunately doesn't mean perfect for the ignition parts and if you have one of those cheap electronic ignitions fitted they can do very strange things, especially if inadvertently fed reduced voltage via the ballast resistor (not always obvious)
Good luck!

If you can get the main caps off in situ then you can change the main shells without damaging them if you are careful. Cut yourself a plastic strip just thinner than the bearings and just narrower. Piece of filler spreader works well. Must be kept spotlessly clean at all times. Use this to push on the non-tang end of the bearing and roll it out. You may need to give the end of the bearing a tap with wide bladed screwdriver and hammer to get it started. If reluctant to come out once started, you can roll the crank over in the same direction to help. Refit is more or less the reverse. Oil the new shells before fitting.
Have successfully done this on several Triumph engines, including once in a London street. Don’t recommend that.

Probably depends on how old the donor vehicle is and how integrated the ECU is with other systems. Older stuff the biggest worry is likely the immobiliser.
Fairly sure the D series is reverse rotation…..

Well, I couldn’t spend that much money on a car….. because I don’t have that much.
Not money well spent IMHO.
I’ve had a car for 36 years, in service and all the road for all but the first year and I don’t think I’ve even spent £20k on that (provided I leave the fuel out anyway!)

Triumph Herald/Spitfire/Vitesse etc rack goes in front of the wheels and would also be easy to shorten. Two different ratios available too.

At what point are you trying to separate it?
I take it you seen this (or one of the many similar ones)

Compression has to be really quite low to stop firing and compression tests on cold engines that have been standing for months/years can be seriously disappointing.
If you’ve got 60+psi on most pots it should run after a fashion and once you’ve got it thoroughly warm, another compression test will give a better indication.

Meant to say (seems I no longer have editing rights?)
OP symptoms sound like the receiver dryer (what passes for it in your system design) is clogged. This means the pressure downstream of the orifice tube is nearly as high as upstream so the system works very poorly.

While I agree in principle to the above, the challenge (in this neck of the woods at least) is finding a “specialist” who
a). Actually knows more about automotive AC than I do (and I don’t know much!), or even knows how to work his automatic machine properly……
b). Doesn’t expect two limbs and a kidney in payment.
“it’s yer compressor mate”. Two different vehicles, 4 different places. It wasn’t on either vehicle….. it was something cheap and simple instead.

Mercedes were the original kings of the extra charge. An base model Benz had no frills at all.

Nice work - as always. 🙂
I have seen similar “pro” work when restoring my GT6. Vast thicknesses of filler (sometimes even lead then filler) covering dents that could easily have been knocked out and finished with a skim of glaze. Also vast thicknesses of bog covering untreated rot and disguising misaligned panels.
“Panel beaters” who are actually bog sculptors with almost zero metal-working skills 😡
