That does look terminal.

The most common carb is the one in picture 3 , the main adjuster is the one at the very bottom of the carb , undo locking backnut , wind in slightly for a weaker mixture.

Keith , I’ve managed to find it , PM me your address and I’ll pop it in the post.

Andy.

Keith , I have a manual , somewhere , if I can find it , I’ll let you know , and you’d be more than welcome to borrow it.
I have a few spares for them , including Pistons and rings , and a complete carb , just let me know what you need.

One tip , make sure the crankshaft , and flywheel are THOROUGHLY de-greased beforehand , before de-greasing it does no harm to lightly rub the crankshaft with some fine abrasive paper.

Rather than confusing yourself further , try what I have said , and report back , as long as the points just start opening at 5/32 BTDC , it should be fine. You can set the correct point gap before doing the actual timing , it matters not whether anything is lined up or not , the gap will be the same any where on the stroke.

5/32″ is the correct timing for a 25c, as the 25c has an over centre spark plug hole it makes life far easier , just set it so the points just begin to open at 5/32 BTDC , tighten flywheel , RE-CHECK that it hasn’t moved during the tightening process……….job done.

Top job.

Angus , for some unknown reason mine has been disabled also , I used to be able to message…….but no longer.

Another result then , Bantams are great little machines IMO , I have two , and they get used very regularly.

A 400 should have 400.12 , is it just the tyres you need , or the wheels themselves.

James , best to follow Charlies links , a picture would probably explain matters clearer, or even better post us a pic of your machine.

The rotors on a 220 are centre driven , and side driven on the Bantam , both share almost identical handle bar systems.

I would go for Miller , in which case they have long been obsolete.

I also looked at it at Stanfield , for me the jury is still out deciding whether it’s an original production machine , a prototype , or something that has been very well “home engineered”
Personally , I’m leaning toward the latter two of my thoughts , the hydraulic pump , and certainly the pipe work , hardly seem man enough for the machine , I just couldn’t imagine pipe of that diameter permitting enough flow , and this coupled to a very small pump , with no form of cooling the oil.
I , stand to be corrected over this , and really hope some concrete news turns up.
