I cannot advance or retard my timing. WHY??? The mechanic who installed the cobra intake said he reset it to 10degrees and didn't advance it since that's where I had it. I tried advancing it yesterday and as soon as I moved the distributor just a little bit, it would start to bog and engine would almost flip over. I just left it where it was and it's running fine. Another thing, I can't see the timing line on the timing "thing" (IDK) and neither could the mechanic but he said he set it at 10degrees. I feel like I'm missing out on some free horsepower.
