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.
(IMG:http://www.914world.com/bbs2/uploads_offsite/farm4.staticflickr.com-17836-1409460377.1.jpg) (IMG:http://www.914world.com/bbs2/uploads_offsite/farm6.staticflickr.com-17836-1409460378.2.jpg) 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! |

Wow there are a number of issues base on the photos and what you wrote.
There are a number of warning signs to this engine that should tell you don't assume anything is correct or working. The paper under the coil mount and someone cutting the top engine tin on the passengers side says to me that a number of short cuts were taken. Take this into account during you trouble shooting. I would check the compression on all cylinders. If it is low across them or one is very low then you won't make any progress. Next check the points, cap, and wires. Sounds like you have started that. Verify that you have spark on on 4 plugs. Next pull the existing carb if you are wanting to work with it and clean all of the jets and check the float level. Check for debris in the carb and filters. I saw a pressure regulator for the fuel lins close to the cut tin. After you verify the fuel pump make sure this is set at no more than 3 lbs. If you pass all of these then you will be ready to start fighting the single carb battle. |
