First time out since resto.didnt go good.Need some help.
Well after ten years and a lot of work my 70 is ready for the road again. So i thought. I took it out today and have some engine problems. Engine is a 406, basically stock, a little work to the heads,mild cam,Edelbrock RPM intake,Edelbrock 600 carb and HEI.Auto trans. No real road miles since rebuild. Just a lot of moving it around running time. Engine idles good but when i take off it boggs pretty bad then will accelerate bog a little higher in the RPM range then just runs real rough.After it cools off and i come back the next day I notice a little anti freeze will come out around the front of the intake where it seals to the block and a little around the the gasket by the valve cover.But its gelled up, not liquid. Also notice white smoke when i first start it up. I am thinking maybe an intake leak that is also leaking internally? I also notice that when setting the mixture screws the car will run better with one of the screws turned all the way in,then gets rougher as i back it out.Only back it out about 1.5 turns. What does that mean? I had the car running very good with a different carb (that i dont have anymore) i bought this carb new and am wondering if there is a problem with it. Im going to change the intake gasket first and go from there.Another symtom is that the idle will vary a lot.For example i had it idling around 1000 RPM. Took it for a ride and when i came back and put it in park it was up around 1500RPM. I backed it down to 1000RPM. Another ride.came back and it was idleing so low it wanted to stall.So i adjusted back to 1000 RPM.Timing is set to 8 degrees BTDC at idle.Vaccum advance is blocked off. Any thoughts?
