So I was changing my struts, and a friend who also owns a z was helping me and noticed I have an l28 in my 73, but with carbs, not fuel injection . At the moment, I dont know if I have flattop or roundtop carbs as a previous owner did the swap and I've been too lazy to check. Now, for the issue, while I was working on the struts, my friend messed wit the throttle linkage,but just pulling it, not adjusting or anything, and when i turned the car on to go home, the idle was ridiculously high, like it sounds like its steadily revving (I dont know how many revs as the tach doesnt work :S). Even before the messing with the throttle linkage, the car took awhile to turn on, and still does. Plus there has been a clinking noise too. I have thought about getting a carb rebuild kit, electric dizzy converter (as maybe high idle is caused by messed up timing?), or rebuilding the engine as it is old and feels enormously underpowered, which I will do eventually as cash permits. Please help!! I dont wanna drive the car in fear I blow my engine, plus I need a cheaper solution as I am on a super tight budget. Thanks!
