Hello everyone, I just bought a 1980 MGB that I will doing a V8 conversion on and I have a quick question. Whatever idiot had the car before me did some major rigging and there are cut wires and hoses all over the car. He removed the emissions lines but he left the components, liek the separation valve in the trunk, the lines, the canisters etc.

So my question is, all I want to do is get the car started and take it for a quick spin just so I know the negine works before I sell it, but I want to go ahead and remove the parts just to get them out. I will be tracingf lines etc, so the less stuff in there the better. If I remove the canisters, will it affect any of the ability to get this car runnubg? I know it ususally doesnt but it looks like there is a line going from one of the canisters into the valve cover? Do I need to re-route any of these lines or can I simply disconnect all the canisters etc and take them out?

No it won't affect your ability to get the engine running.<div class="ubbcode-block"><div class="ubbcode-header">Quote:] I know it ususally doesnt but it looks like there is a line going from one of the canisters into the valve cover?[/QUOTE]Yes, one of the lines does usually connect the valve cover to the charcoal canisters. <div class="ubbcode-block"><div class="ubbcode-header">Quote:]Do I need to re-route any of these lines or can I simply disconnect all the canisters etc and take them out?[/QUOTE]You can take them out. They're there to 'scrub' the evaporative vapors before entering the atmosphere. Their removal should not affect the running of the engine. However, there is an anti-run-on valve that is connected to them and the stock carb (assuming it still has the single Zenith-Stromberg carb). If this valve is stuck 'on', you will not be able to start the engine unless the carb has been disconnected from the charcoal canisters.

you can leave it on without the vacuum line connected to it. Or get fancy and fabricate a plate to cover the 2 holes in the manifold...
