winter project #1 - bike carbs
as above i am starting the first of my winter modifications with the bits and bobs i have accumulated over the last few months, when its been nice
enough weather to work on the car i end up driving it! which is good i guess, anyway its now all tucked away in a garage and i have a set of bike
carbs to replace my 38 dgas carb, im pretty sure i have everything i need, bike carbs, bike fuel pump, manifold, rubbers, h&h solutions dizzy and
new coil. all i will be ordering should be the hoses/conectors. its a 2.1 pinto engine and fast road cam, and a set of fireblade carbs jetted for a
2.1 with fast road cam and big valve head. is this ok.
so, first few questions,
firstly the pinto i think runs 8mm fuel lines, and the bike carbs run 10mm. so do i need to change all the fuel lines to 10mm or will the fuel just
speed up in the 8mm bits and be ok in the 10mm parts?
also the fuel pump is a gravity feed, so below the tank obviously, the take off from the tank is at the top, is this going to be a problem? also any
pictures of fuel pump mountings would be great, and any setup pics too.
plenty of questions to come im sure,
cheers for any help

Bike carb pumps aren't too fussy where they go as long as there are no air leaks at the pipe joints, though below the tank is best [I've
had mine in the engine bay as well and it worked fine].
I shouldn't have thought having the take off at the top of the tank would be a problem as there must be an internal pipe going to the bottom of
the tank.
The fuel hose will probably expand to 10mm, depending on what type it is - warm it up to make this easier.
You are welcome to come and look at my bike carb setup [on a Zetec]. By the look of it we live fairly close together.

cheers for the help guys, right ive just been out and taken of the dowdraught carb and manifold, didnt get to much coolant on me!
removed fuel lines down to copper pipe, removed pinto fuel pump.
ok i meassured the copper pipe and its nearer to 6mm, then into 8mm tube, should i just get an adapter to 10mm, there is an adapter on the carbs from
8mm up to 10mm. hmm.
anyway all seems good, for the time being. anyone point me in the right direction for how to remove the coil and dizzy.
and also a good place for braided fuel, air and water hose, isnt there someone on here who supplies them? also may aswell put an oil catch can in.
thanks all, and any advice on the fuel line diameters would help.

To remove the old dizzy first turn the engine to TDC on number 1 cylinder and line all timing marks up
then use a 8mm spanner and remove the dizzy clamp
Then slowly pull the dizzy out [ be careful of the oil pump drive some have clips on them ]
IF its a H&H dizzy you have remove the old coil you should have a new one from H&H
 
H and H dizzy and coil
