Not sure if this is well known or not, maybe I am the last to know. I saw a trick done today by a neighbor who was kind enough to come take a look at my car. I have been having problems with it running rich for a while now. My buddy (also my neighbor) asked his neighbor to come take a look because he is a long time mechanic and muscle car guy. I started the car, he listened to it, smelled the exhaust, then asked for a can of carb cleaner.
He alternated spraying carb cleaner at the air horn from about 3 feet away, so just a misting, and tweaking the air screws. He was listening to what the engine did when he hit it with the cleaner. If the engine slowed down it meant it was running rich and tweaked it down, when it sped the engine up it meant he had gone too far and it was lean. after about 2 minutes tweaking, listening, and spraying he had the car running better and sounding better. So that is a little trick for anyone looking for a new tool in the box.
I took it for a run and it sounded pretty good. I may come back a little bit to the rich side as the car had a stumble at lower speeds.
Another thing I noticed was the transmission was off. taking off at the first stop sign the car came out of 1st half way through the intersection. I am wondering if I just need to adjust the clutch. It has sometimes had an issue getting into 2nd as well. Then, with the car running in 3rd if I let off the gas sometimes it will come out of gear. Seems kind of odd, I figure it is in the gear levers under the car and outside the tranny. anyone have any thoughts?
