I believe this thing would be carbed, what model crx is it? I hate the first gen crx's. They're so ugly, however the suspension handling makes up for the ugliness of the car. I personally wouldn't waste a dime on the car and save up and get a 88-91 crx. They've been going for extremely cheap lately. You'd better check the oil by looking at the dipstick and making sure there is no water in the oil. Just make sure there is no oil leaking around the head or anything as well. I think the motor would be a d15b series if it's an hf or something. good luck wit it.
