72 Datsun 240z

Here in Panama we use 95 fuel. Mechanic advised to use an octane booster. The thing is how much in half full 16 gallon tank? The whole can or half and then fill up the rest of the tank with 95 fuel?

Hi Jon, Mechanic just confirmed he had advanced the timing to get a quick response in first gear with the hot coil. Should i retard it a little bit? If so how much?

Im experiencing a ratting noise when accelerating in 3rd gear on my 72 240z. Is my timing too advance?

Well im going to send it to Power brake exchange. I do have this kind of symptoms om revs going up and down during traffic jams. Any way to check this before shipping it to Washington? Maybe a pressure suck gun?

This guys are very slow responding emails. Need another shop!

Car is running a little bit better now with the MSD Blaster 2 coil maybe its masking the problem only. Still testing the car. I did noticed the mechanic adjusted the carbs as follows: 4 turns down each carb, 7 at idle screw for front carburetor and 10 at idle screw for rear carburetor. The fast idle screw when raised to 2500 rpm gave different measures on front and rear carburetors.

Just email them, filled up the form and send them pictures of my original brake booster. Hope to get a response from them so i can ship it from Panama to the US.

Thanks. I live outside the US. Getting such booster into the US will pay an import tax.isnt there any shop that can sell me one instead of doing the exchange?

Im planning on buying a kit to rebuild the brake booster in my 1972 240z. Any reliable kits and how difficult is the reman process?

This is how the msd blaster 2 got wired to the tach, distributor and ballast. Hope im not missing anything. Tach is working but plug 4 is still getting fouled at idle.

Car is running fine with the msd blaster 2 coil. Tach is working.

Well just to let you know mechanic managed to make the 240z tachometer work with the MSD Blaster 2 coil which i believe is 0.7 ohms and pertronix 1711 ingitor module. I hope it doesnt burn the 1711 ignitor.

Does anyone sell these float syncs for su carbs anymore?

You are right! Mechanic should get this engine running with pertronix ignitor module 1761, 1.5 coil and 1.5 ohm ballast.
