88 GT T-Top running (rich)?
Hey guys I picked up an 88 GT 5spd T-Top project car about 2 weeks ago. It had a hole in the timing chain cover that has since been fixed. On the first start up it smoked black constantly, assuming it's running rich. It fouled the plugs out and wouldn't start, so I said hell lets replace plugs and wires. It then ran better but still smoked black. It runs good to me has good power (used to driving a 3.0 5spd ranger). Could someone tell me what all I should check and in what order? I've searched on here but I don't know what to start with!
Thanks in advance. When I get this figgured out I'll let you all know. Yes yes, I'll post pics up sometime
Also If someone could show me a write up on how to remove the headliner in a t-top that would be great as it needs glued or replaced which ever I choose. Thanks
