A few more pics would help.

Graham , you would be surprised what seals are still available , I did a back to front restoration on another Howard 700 over last winter , and got every seal I needed. You may well not get leather clad ones , but later equivilant are often available, which are better for rotor boxes anyway , as grit does not get impregnated in them

Provided you can supply the engine code numbers (stamped in the cowling) Garden Hire Spares are who I usually deal with for coils , they’re a sister company of L&S Engineers , always helpful and give a very swift service.

George shead at villiersparts will sort you out.
tmax , we’re talking float needles here , not fuel needles.

Spot on format , well done all involved.

Firstly a warm welcome , Bantams are my favourite small Howard , and I use them alot for potato and rowcrop work. Infact I’m now in the process of working on yet another one , which I’m building from the heap of broken/spares machines that I’ve accumulated over the years.
Look forward to hearing of your progress.

That’s a good idea , and you’re spot on about differing types of alloy used to make carbs.

Despite what you have read on the internet , my early experiences taught me the hard way that acid “CAN” damage very fine threads ,and I managed to ruin a carb , and it wasn’t because of a too rich mixture of acid. I took experienced advice from a good friend and went over to drain cleaner , and have had no problems since.

If it’s a carb I’m relatively familiar with , and I know there are no hidden/unknown rubber seals etc., I use a little drain cleaner in the ultrasonic , in your case it would definately work fine , as in a 24T2 there are no hidden “dangers”. A 15min cycle in mine with a little drain cleaner will rid the white corrosion deposits , make sure to drop it into some fresh boiled water , and finish by blowing dry with airline.
Glad you had success with the adjustable jet , it’s the only way to go.

I use liquid grease(00grease) quite a bit , but it is vitally important to ensure that you have no brass or bronze components in your gearbox if you have you will need the suitable straight grade SAE.

Charlie Moore is the man for all things Monrotiller , I’m sure when he gets back from Weeley , he will have the answer for you.

24t2s with fixed jets are ok provided there is very little to no wear in the butterfly shaft , and your engine bore/valve set up is also ok , this is especially so for any application that requires smooth tickover and smooth pickup of revs.
I would always go down the route of changing fixed to adjustable , it eliminates all the USUAL problems with the fixed jet , I had a Coleby a few years back that was a comlete pain until I changed to adjustable.

“What surprised me about that engine was the amount of wear on the rings, bushes and big end rollers. Yet the cylinder bore was OK!”

You have to take into account , that extremely few of the machines that come into our hands are all original , many will have had odd bits and pieces fitted to them to keep them running back in their working days.
Soon after the War , my father bought a ModelL brand new , AutoCultos policy then was to have widespread local dealers , who would stock alot of the essential spares. Our dealer was around 8miles away , when cylinder wear started to give poor performance , Father would take the cylinder there , pay a surcharge and walk out with a rebored barrel and new piston , he did this several times in its working life , and it had a HARD life , but it only had one service exhange crank.
This may go some way to explain your possible mismatch of engine bits.

Andy.

I did think it should have been V111C , as they were the model used by Allen and Simmonds. Should you ever need one I have a new piston (cast iron) for one of those , along with a used , but good cylinder barrel.
I would go along with your views and measurements , but as you say , we’re not dealing with formula one engines.
Many years ago I fully rebuilt a 25A on an AutoCulto model L , the crank rebuild cost a small fotune back then , I dread to think what the cost would be today.
