spark plug issue
A guy brings a 93 jeep into the shop, he bought this jeep with an older 350 engine already in it. He complains that it has a hesitation when acclerating from a stop sign or at a low speed around town. Now this motor has an electronic igntion on it, with what looks like a 650 or 750 edlebrook carb on it, also with what sounds like a mild beefy cam in it. he bought it this way and is not sure what size cam is in it. but the issue he is having jus started a few days ago. after checking timing it looks to be 31.5 degree'* advanced. and the spark plug that i took out of the #1 cilynder is very black and is CR43TS delco.. my question is that, is that plug to cold of a plug for that motor? or is there something else that i could check?
