Sorry for the slow progress guys. My house had bad plumbing, so I'm put up in a hotel for the time being. My car, being immobile, is still at home. I'm gonna see what I can get done today with my buddy.

i've already checked the spark and it's there. so im not really worried about it's presence so much, rather how much spark there is. it looks kinda weak, and that's what's bugging me.

i would hope spark is good.. i just replaced the plugs. but i guess i could order a new rotor and plug wires to be safe. i was just wondering about vacuum because i was looking at the engine a few days ago and i noticed that there were a few holes in the motor and some vacuum hoses disconnected. i dont know what went where either.. it just came that way. advice on that note?

awesome guys! well, i'm gonna try all the stuff i've learned on this forum in the past few days. you've all been a great help. but, if it doesnt start up after i put some oil in the cylinders and all that other stuff im gonna have a mechanic strap it up to all the machines he's got and take that engine apart. it's going down.

Hey guys, since I'm definetely not a mechanic and I want to do an engine overhaul I was looking for advice on what should be replaced. Here's the specs on it, from what I know. 1974 L26 w/ 240Z carbs. (not sure of the year) everything else is stock. uhm replaced rear electric fuel pump and valve cover gasket and some random fuel hoses. Which reminds me, im planing to replace most of the fuel lines too, they've been sitting for 10yrs. Im not looking to upgrade anything, just get it back to running condition, since it's gonna be my tester motor. Im planning on swapping an RB26DETT in, just for planning info. So, back to the question. What should I replace? Pistons, rods, cam, vacuum hoses, fuel lines, ect. What else?

Kinda a mass reply here... I've replaced the spark plugs. What was in there was NGK Platinums. I just got the generic equivalent from Champion. It's supposed to be just a tiny bit cooler. Um.. Spark is there, but weak. I put 91 Octane in it though. And my WyoTech friend says that compression is good. If i remember right, it was 60psi in each cylinder? Does that sound about right? I dont have my manual with me... I'll try putting some WD in the cylinders tommorow after work. Something I haven't done is check the hard fuel lines. I've replaced most hoses, but I'm no mechanic, so I haven't touched the internals. I know a guy who can hook up some fancy gizmos to it. Problem is I gotta tow it to his shop... so I'm trying to get as much of it done by myself. Do you think vaccum might be a problem?

The guys over @ HybridZ wouldn't help me... I recently bought a late model '74 260Z. It's the coupe model too. Uhm, the kid I bought it from said that it only needed a new battery and the fluids replaced. Did that first night and tried to start it. Nothing happened. It turns over great though. Through various sources I've gotten instructions to check the fuses, replace the rear electric fuel pump, replace fuel hoses, check the mechanical pump up front, replace the 10yo gas (did that first night too) and get a manual. Done all that stuff. The manual I have, said that the elec. pump doesn't start until 400rpm. The mech. pump looks to have too much play in the lever, but the offset cam lobe makes up for it, so it works. It's not clogged, and both new and old elec. pumps work. I also sprayed starter fluid in the intake and put a little gas into the swapped 240Z carbs. Buddy o mine from wyotech put propane right into the cylinders. Any other pointers other than replacing the fuel system? Cuz all it's done is backfire...
