Picked up my '74 2.0 this evening after getting a new set of EMPI 40mm's in place of the Weber Progressive that was on there when I bought the car last year.
Wow. It's like a different car. I was expecting a little better throttle response and less gurgling/flooding, but here's what I found: No gurgling or stumbling at all... big difference there. Instantaneous throttle response Quicker throttle take-up - I think the cable has less play than before. This is the biggest change and one I'll have to adjust to... I found myself revving to 3K RPM to get rolling in 1st gear. Got to get used to a softer touch. Smoother running at idle and throughout the rev band Big difference in sound.... this one I wasn't expecting. With the single Weber, there was a lot of burping, popping, etc, sounded pretty mean. Now it's got a deeper, throatier, smoother howl. Didn't touch the exhaust, but I swear there's a big difference in the sound. Can also hear the carbs sucking air at times. All of this is more impressive since I was driving home in 30-something degrees. The Weber carb had major issues with cold temps, due to fuel condensing in the intake runners. My mechanic also changed the trans fluid. So far I've only driven it ~10 miles on a scenic drive home from the shop. Hope I get another drive this week, although they're predicting snow... which means heavily salted roads. (IMG:style_emoticons/default/sad.gif) Oh, and here's my "ask": My mechanic had a very hard time getting the carbs dialed in. It's running rich right now, but he said the engine doesn't seem to like when he leans it out. Can others please share tuning/setup/jet sizing/etc. tips for my setup? It's new EMPI 40mm carbs on a stock 2.0 motor, for street use. Much obliged, and happy (IMG:style_emoticons/default/driving.gif) |

First the carbs.
Find out what jetting you have on them now, get all the sizes and write them down, they can be tuned better, but you may need to change jets and venturis. On the fluid...dab your finger in it and smell it...gas and brake fluid have different odors. If you dont have jacks and a set of jack stands, now is your excuse to buy them....you cant own one of these cars without jack stands and a good floor jack. Rich |
