Can someone give me a rough idea or point me to a place that has instructions of how to check/adjust the timing on my 350? Also, when my car is cold it starts instantly but when it's warm it acts like the battery is weak (barely can tuuuuuurrrrrrn oooveeerrrr the motor then suddently it starts turning over and starts and runs good.) Any ideas on that? All my co-worker said was, "Yeah, sounds like a chevy." Real useful info huh?
