Doctor, No i am willing to learn an take any advice. The truck is in my hands now. From what ive already learned hear, is the reason its a do-it-myself project from hear on. Much easier to learn an figure it out.. It cant be rocket science right. I will update more accurate info.. Starting with the compression an taking the advice given Thx again mike

10-4 Both of those 2 coils have spark. My guy told me they were nearly 90 even, close to even.. Not very smooth running tho. he thought nothing of it being in the motor (but im with you). what other symptoms can be checked causing that kind of low compression if any?.. He mentioned the converter. Had it checked at the the muffler shop an its flowing like it should. I will do my OWN compression test an update some more accurate info. Its an old-worn truck, im sure it needs a valve adjusment an rings.. This is about to become a do-it-myself project. With youtube, a haynes manuel, an a helping hand, hopefully ill figure it out haha Ill update compression .. An move on to the tear down. Thx again

Distributer connections are good. Compression is good. 90+ in all cylinders Checking converter, honeycomb may be stopped up.

@datzenmike: thank you for the welcoming The compression from what my guy said.. All cylinders are 90 or over. Tho it doesnt run that way. Also the truck doesn't smoke or burn excessive oil I assume your talking about those 2 main resistors. they both are firing properly. I have yet to get into the timing but im Definetly heading that direction. The valve lash/ does that mean valve adjustment an clearances? Im trying to declare everything i can before i go into the valves an timing. 1 wing nut ? Stock 2 barrel carb.

First off, i have much love for this truck. However i am not a mechanic an i do not know what most of alot of you do. So the advice an any information will be absolutely helpful to me.. Id love to learn an of course fix this issue 1985 nissan 720 z24 225k The problem: Has no power. Bad idle. Some oil in the air filter. On a straight highway the max speed i can do is 70-75 mph. On a incline, even if i were to down shift, it just want hold a steady speed. Has a rough idle (carb related from the sounds) an sometimes it will i guess choke out an cut off. At a stop sign (after awhile of driving) ill have to keep in the gast. Some of that may be in the carb but does it explain such lack in power? It really feels like a surge, the throttle reaponse is there, but the sound of it an power is just not the same. Ive had all cylinders checked.. All are nearly the same compression. Spark plugs are fresh. Plug wires are good with good connection to the distributor. ( i did have a cracked distributor, but even before then the problem was still occuring) everything is stock except glasspack exhaust an k&n air filter. Nearly 15000 to 20000 miles ago the timing chain an head gasket were done. I will have to put more detail when i can.. But if anyone can help, i would very much appreciate it. Thx
