I am a noob to this vintage, but I have had a hardbody pickup, and have a 86 300z, but am looking at an 84 720 for a winter driver. Its a king cab, long bed 4wd from Texas, and the body is super solid, especially being in upstate NY. Problem is, it kinda runs ragged. Most noticeable is that when launching from a dead stop, it stumbles all over itself and wants to stall. Have to rev it to 3 thou, slip the clutch, and hope, but once its rolling, sounds like it runs as it should. Idles good too. Without load, it seems like around 1800 rpm it hits a dead spot, looses rpms unless you let off. It has had its electrical butchered, poss egr deleted? elec choke is unhooked, along with anti diesel cylinoid, so the guy says. Has had the block decked, head checked, new water pump, head gasket, dist/ wires etc, claims upper end it mostly new (carb came a parts truck he had) Also, ign switch deleted, now is on toggles w/relays. Im super interested in it, but am foreign to the carby lifestyle. I know its impossible to diagnose probs for sure with out being front of you, but what you guys think-simple as plug wires being out of place, super bad egr leak, carb needing rebuild? Also it came to NY from TX via Colorado-mebbe was rejetted for higher alt, needs to be corrected? Truck only has a 500 dollar pricetag, and its breakin ma heart here for NO RUST
Thanks
