1983 Datsun 710 4 cyl Two Wheel Drive Automatic 200000 miles
have 83.5 king cab long bed, z24 engine, when engine is idling, it idles solid, but tail pipe starting smoking grey smoke with a hint of gas smell about 30 seconds after the engine starts, doesnt matter if engine is cold or warm.
When truck is going down road. no smoke, has plenty of power. the guy who had the truck, didnt know what he was doing at all, truck has been beat up. wiring problems ,the works, i need help here, ive been told the reason it smokes is from bad valve guides , rings, the the carb is choking itself, HELP !!!!!!!!!!!! LOL
Check if the choke is adjusted properly if not could be the cause of the smoke and fuel coming out-flooding it out during initial cold starts-also the choke plate should be wide open.
A puff of blue smoke during initial starts could be valve seals/guides/stems problem. Check engine compression wet and dry tests
