That was my first impression but I found that difficult to believe. Does anyone have an idea of how the bushings are oriented on other makes of cars?

I can't figure out the bushing orientation in the pic.

Measure your old one first. Disassemble both and use the best pieces from each one to assemble a good one. Adjust the new one to the original's length. I'd start with steel wool if that doesn't work, fine sandpaper.

I like the sea of 510s sitting behind the two US land yachts.

I've never seen a blond wheel shown in the early ads nor the deeper red (maroon) sported by the almost NOS wheel being held for ransom. IMO it's been refurbished.

Use 4' piece of garden hose as a stethoscope to pinpoint the noise while starting the engine.

How old are the spark plugs? The only time my Z misfired above 4000 RPMs was a track day. (Murphy's Law) The old plugs looked pretty good, but a new set cleared up the problem.

I'd look into shoulder bolts. They're made to have a bearing ride on them. You may get lucky and find one that will work or make it work by modifying it.

Advanced ignition timing can cause broken rings and in severe cases holed piston tops. The first symptom is engine knock when going uphill. The knock is caused by the fuel-air igniting in the combustion chamber while the piston is still rising. (BTC) I know little to nothing about the 123 system so I have a question. Does this system control ignition advance to individual cylinders or does it advance all six with one function? Another way of putting it is could the system provide too much advance to one cylinder and not the others?

Take a peek into #4 with a borescope before you tear it down.

I'd use the 2.5 psi - 4.5 psi pump for Weber DGVs.

Your choice as to which surfaces get the dressing. A thin coating is all you need. Any more than will result in dressing squeeze out. I've installed pumps with no dressing, just a bit of grease on the gaskets and had no leaks. No need to lube the pump.

I believe the bucking is caused by a lean mixture. Too rich would just result in a lack of power but not bucking. The float levels are the primary mixture adjustment. The mixture screws are the fine tune secondary adjustment. I'd pull the floats and check the float adjustment and or the fuel level. How many turns down are the mixture screws when it bucks?

What weight oil are you using in the SUs?

The retainer can be replaced without removing the head. Same procedure as changing valve seals without removing the head. One of the members will report on the brand and model # of the valve spring compressor that is used. I've got brain fade.

@siteunseenHappy Birthday, Cliff.

150 psi is better but it should be a little higher. Is there any valve noise (clatter or clicking) after the last valve adjustment? If not, I suspect the valve adj. is still too tight. I pull all the plugs during a compression test and hold the throttle wide open. After checking all the cylinders, recheck the first two again. They will usually be higher the second time around due to oil circulation.

Those compression #s should be 165 or above. Are you sure the valves are adjusted correctly? Just reread your first post. No specs on the cam? As in no lash adjustment specs?

So, the fuse blows at the first key stage. I'm assuming that is accessories. The next stage is on and the last stage is start. If that's correct, you've got a short circuit in one of the switched accessory circuits. Which fuse is the one that blows?

It's just a flesh wound.

Geoff, sorry to hear about Lillith. Couldn't open the pic file either. Can you give us a description of the damage? I have a lot of parts just waiting.

Nissan cam or aftermarket?

Come and listen to my story about a man named Jed A poor mountaineer but he had a brand new Zed And then one day he was drinkin' up some shine And said to himself I'm gonna make this car mine

Choke cable adjustment can be quite finicky. Hitting that sweet spot that gives one full choke and raises the nozzles all the way up usually takes a few tries before I'm satisfied.

Sure sounds too good to be true.
