Help me get my 2.0 running smoothly! Options

[jaywood]

I just picked up a 74' 2.0 and I got a few questions. We bought this thing as non-running. It runs....but it's real rough. What can you tell me about this carb setup that came installed? We have the factory carbs as well but it came with this carb setup installed. They appear to be brand new and looks like the PO never got the car to run right with this carb setup installed.

Should there be a vacuum hose coming off the carb? There's a port for it but no hose has been run.

We pulled the plugs and all of them were in rough shape...#4 especially. Cylinder #4 has a timesert on the spark plug threads and looked to be drenched in fuel. The rest were just old and worn out (and none of them matched...had 4 different plugs in there, lol)

We also did a valve adjustment. Wow were those out of spec. One of the intake valves had almost .120" of clearance. (IMG:style_emoticons/default/aktion035.gif) So we got all the valves within spec and tomorrow will be putting in the new plugs. Hoping to get this 2.0 running smoothly!

The breather hoses seem to be cracked at the ports.


Any other recommendations on what to do/check to get it running proper would be great. Thanks 914world! Great community, glad to be a part of it!

The single carb setup will never be good. The biggest problem is the intake runners are way too long and the fuel doesn't stay atomized well, so it will never be smooth or efficient.

Hopefully you have everything you need to get the duals set up. It was fuel injected from the factory, not carbed. But odds are converting back to FI will be more challenging now as there are a lot of parts that are probably long gone.

Can you tell what kind the other carbs are? Dellorto or Weber are the most common. Do you have the linkage for them? Any idea what size they are? 40s would be nice. Any info about the fuel pump? The factory fuel pump would put out way too much pressure for a carb setup (like 30psi instead of 5psi), so hopefully the PO put a proper pump on.

Thanks for the response guys.

The other carbs that we have are Webers and yes the linkage is there. I do not know the size of them, I'll check that out tomorrow. No info about the fuel pump either, I'll have to take a look at that as well.
