Exedy clutches are good and you can buy them all day for 100.00

Better start from ground zero. Set the engine to TDC compression and remove dizzy and check alignment of shaft and alignment of rotor. You might be off a tooth and the way advanced timing was to make up from there. You never know what the PO has done with this car and don't take anything for granted.

Good luck on the sale. I have been studying the eBay sales since I will be marketing a 71 in the near future. What I have seen is that there is no ryme or reason to what these cars bring on a given day. The values seem to be based on purely personal taste of the buyers. Then there's te question of how much do you fix or not fix, to make it presentable.

Don, So are you running SU's ? Have you or do you know how to set float levels? You stated that the car feels like it is running out of gas- maybe it is! Float level is very important , and revving it up in the garage tells you nothing about loading float level.

Or you can borrow a vacuum tester/ guage from maybe an Autozone and measure engine vacuum and test the "dizzy" at the same time.

Okay, so you said you checked the carb tune and it was good-can you explain what or how you tuned or synched the carbs?It seems to me a carb tune issue. What experience do you have with SU's and what experience does the "shop "have? Did you check the synch at 3000 rpm?

Not sure why you started a poll for this issue. It helps us diagnose issues with a detailed history of any engine work or engine status; I.e. Any recent work done? Did this issue just start recently? Did you make sure that your coil and dizzy are impedance matched? Why an electric pump and a mechanical? What kind of carbs? Engine rebuilt? Compression check?

Black looks good on an engine and I did the por-15 paint-no regrets-EXCEPT, when you have any oil leaks, it's much harder to see them or where they originate with a black engine. But you won't have any leaks;) Looking good!

Sure sounds like you are fighting a vacuum leak- maybe your brake booster which would tie the brakes into all of this. Check your banjo bolts as suggested above Don't drive the car until you have the brakes figured out- that's a bad scenario ! Disconnect your vacuum line from the balance tube that goes to your brake and note any changes. What's your timing doing at idle and full advance.? Condition of battery? Is your battery receiving full charging voltage ?

You need to define ' not running good'. Any other history on the motor will help

Not sounding good. A compression test will tell you if you have damage. Just because there is no noise now doesn't mean you escaped damage- you might have just clearanced your valves with your pistons

Good luck getting racing carbs to act like FI! In no way am I being sarcastic , it's just the way I am looking at my triples. Not sure you can get racing carbs tuned well enough to stomp on them at. 2krpm and think they will react the same as stomping on them at 4krpm. At 2krpm there is probably too much fuel for your engine to swallow- thus hesitation. Then your AFRs look way off while the motor is trying to burn off all that fuel. Thankfully you enjoy tinkering, because it will take a ton of it!!!

My RX-7 pump puts out over 3psi easy. I am also running fuel via dead head method . I am suprised you aren't getting more---especially with the engine not running

Gotta have a L6 in it. For me--I would build a turbo Z to fullfill my HP needs. Though I have nothing against someone doing the LS1 version, I would rather pop my hood open to a beautifully polished out L6.

Not a FI guy, but sure sounds like the cold start valve, especially if the engine does better when warm. Of course that is probably all tied into the other switches you mentioned. Google EFI BIBLE, might be helpful. Should be some simple OHM tests for testing those switches also- check your FSM

Did you try moving the dizzy while starting ? Try a big change by turning the dizzy to see if you are possibly off one link. If it tries to start or runs, but poorly, then you probably are not lined up right.

Let me guess one of the reasons you are glad you kept this car- all the attention the car gets !

Those engines are tough and can sit for a long time and come back to life-too bad the bodies don't fare as well. Welcome here and good luck.

Good time to uPgrade to electronic ignition. Do yourself a favor an get a pertronix setup or a zx dizzy Good luck on the fix side of your troubleshooting

5th opinion- ignition Check everything for tightness- plug wires, wire leads Check the cap for cracks Look at your points- you might have lost a contact pad Check for a big vacuum leak also Check fuel filter for clogging

Might be the same -I don't know. But they offered the loop cut and the kit looks pretty good. I bought one of the ACC kits for a 81 and it worked out well.

Jerry , Whenever you get the car back to Indiana I would like to drive up to Richmond to see it. It looks amazing, looks like Les made you a pretty car

I noticed the prices you put on there- 310$ for the pair of cushions!! Classic Datsuns web site shows 405$ for the set of covers and cushions- so I guess that's not up to date?

Welcome to the rx7 pump club. Have the same pump in my car- very quiet. So quiet I left the ignition on all night with the pump running- still going strong

I just realized that I never updated any pics of my Mikuni CAI
