Twins / Re: Starting hot engine

My Maggie hates restarting when hot also. I wish I knew why. However I found if you swop the plug leads and kick over until the exhaust pops, then swop back, it starts. Why?

We call these brake blocks and used as low speed and parking brakes on a power car. Common on feightbut not so  passenger trains.our 373 s use them and the cylinders have a ratchet and spring which keeps the brake on when the air bleeds off.

train brakes consist of 2 friction pads squeezed together on a disc by a pneumatic caliper. no pistons or slides involved. unless in valves . high speed braking is controlled by traction motors - regen braking.
in frozen weather most people leave the car at home and catch the train instead.

from my limited experience with an a65 spitfire. i found the highly tuned motor was very fussy about carburation. the new amals have removeable pilot jets and thats the direction i would go in.
check your spark with a strobe. if you have points are they insulated properly or sticking?

hi ken, luckily i m not a lawyer. but it  seems triumph disc front ends are ok. no mot required.
if crofty can source a t160 font end all the better as the forks are slightly lower i believe. also steering stop has to be made and the steering damper arrangement thought .

hello, a t140 disc front end on a bsa a10  was always a common mod to improve braking. its the restoration nutters who removed them. another mod is the later twin leading shoe front brake. i guess a lot of us will now have to have an mot.

hi julian,
i missed article in the star as my membership ran out without knowing. i have the chaincases and 2 a7 alt cranks. small journal. any idea who used these back in the late 50 s ?

hello, unfortunately the chaincases are more rare than the crankshaft. and the crankcases rarer still. s.r.m. had some made about 30 years ago otherwise its ebay.
is this the crank that was on ebay around 3 months ago?
i was outbid on one then.
