right, after messing around (see other posts) i'm still not getting this baby to work properly
next thing to do is follow and probably replace the fuel line.
i've rebuilt the pump. cleaned out all the carbs. but and this is something of a big but (sorry, gone off for childish giggle)
i can run her from a can of petrol on the floor in front of the bonnet but it's not sucking the fuel through from the tank (again?)
so does anyone have a nice clrear picture of the normal route fot the fuel line?
thanks again
bill

Re: fuel line
Bill:-
I had a similar problem with one of my Javelins many years ago. It would unexpectedly lose
power but if I pulled the choke out quickly enough the problem would clear and the choke could be put back.
The problem eventually turned out to be the filter in the petrol tank.
I seem to recall that there was an official Jowett instruction to 'run a 3/8" diameter drill through the filter', in other words destroy it!
After all, there is an in-line filter and two more, one in each carb banjo.
Of course you have to drain the tank first, and if the filter is blocked . . .

The devil is in the detail!

Re: fuel line
The fuel starts it's journey in the pick up tube in the tank. This may be blocked intermittently with rust . A union on the outside of the tank may be leaking air. The tube then bends over the exhaust and to the inner side of the battery to go through the midship bearing support. There is a union before it travels through the chassis cross member. A petrol filter may also be there. The tube then bends in a convoluted way to cross behind the rad. Could possibly be flattened. The tube moves forward just above the offside carb to a union and flexible pipe delivering to the pump. Note too that the tank must be able to breathe and must not be sealed.
You can check flow of petrol by disconnecting at flexi pipe and putting into tin. Then blow into tank either with compressed air at low pressure or with your own lungs (but take care). Blowing the other way may clear tubes and you should hear bubbling in the tank.
