Smoking & no power 1985 bronco II

[fp4]

I have 1985 stock high milage Bronco II. When I got it from previous owner it had been sitting in horse pasture for several years. I charged battery and poured gas down carb and cranked right up, but would only idle. I put kit in carb and would start and rev up. Idle rough & no smoke. No power would only pull itself in 1st & 2nd some. Replaced map sensor and throttle position sensor. Still same thing no power. Now engine smokes like freight train. Previous owner put electric inline fuel pump on and mounted it near original mechanical fuel pump under hood. I hope smoking is seals on valves just don't know. Many cut and spliced wires under hood and I haven't worked on engines since back in 70s. If I could solve lack of power problem I wouldn't mind tackling the heads and what ever else that needed to be addressed. Body in great shape but interior shot. Hope to rebuild and be able to use at hunting camp. Any thoughts on lack of power and smoking would be much appreciated. Thanks. fp4

What color smoke is it? Perhaps it's gunked up oil from sitting.

Did you change all the fluids, including the gas?

I would go through and check all those wires. I know it's no fun, but if you start clean and just fix that wiring right and know it's done right, you can rule it out. trust me...I've been there with my truck. Some people just shouldn't touch these trucks..
