Cruiser AMC - Help starting

Post  Mickdowning on Mon Jul 10, 2017 6:49 pm

Hi All,

I have just retired a new ignition switch on my FB Cruiser .
However the lights still do not work?
Also having trouble with choke dependency?
Any help appreciated

AMC 25T

Have you got a wirng diagram? The 25T used the Wipac elctrical system. A 6v alternator with rectified DC for whatever. The Wiapc switches were in the mae leauge as Lucas, good when new, but soon caused problems. send me PM and I will send you a wiring diagram, or there might be one on this forum.
All new switches can be bought along with a new proper rectifier. You can also make it 12V if required.

Stay cool Mick, the commonest cause of a leaking carb must be the float needle not seating properly, are you sure fuel is not just leaking from the top of the carb and dripping from the bottom. As bigjim says the choke dependency is likely to be an airleak possibly carb-manifold or crankcase seals, changing seals is cheap and easy on the villiers, don't know about the amc.
I have little doubt you have checked the above already, I know all too well these bikes can be headbangers.

When you say choke dependency you mean it needs it on to run?
As said check for air leaks especially where the carb mounts. Most flanges have a Bow in them.
One big thing on the Amal Monoblock is the fuel height, it makes a world of difference to starting, choke,and running. On the float chamber cover is the word Amal . There is a cast Dot in the middle of it. That's your fuel height. It's adjusted by the thickness of washers under the needle valve. I even flatted a washer down to get it correct.
I have a cover with a 1mm hole and set it to just trickle from this.
You are supposed to be able to do the same with a U tube but I couldn't work this out.
Oh and of course check you jet and needle sizes are correct.

Difficulty in starting and cutting out when the choke is opened slightly could indicate that the pilot jet is obstructed. This is particularly likely if the tank has been sealed with non ethanol resistant tank liner.
Remove pilot jet and check/clear (with nylon bristle) Also check that the leak is not coming from the pilot jet sleeve nut seal.

Regards
Dave.

New ignition switch/light don't work ?

Post  piston 197 on Fri Jul 14, 2017 11:26 am

Is this bike a Light Cruiser 79 as this uses a combined lighting/ignition switch ,?? other cruisers 80 and 84 use 2 separate switches and fitting a new ignition switch on these is unlikely to influence the lighting switch ??
