"I have a PCM Chevy 350, Holly
"I have a PCM Chevy 350, Holly Carb in my 1987 Supra Comp ts6m. When I start it up cold after a few days of not running it, it lets off black smoke for aboute 5 minutes until the engine warms up. Does not seem to affect performance. No smoke after that. Any Ideas? Thanks!"
