Track?? There is no reliable datsun mechanic here. I am following Mark's advice to set the floats at 2.5 turns 1/16 inch. Just remember my car has been overhauled to 2.6 liters and has a schneider 274f camshaft. Its not stock.

i guess that with a set of pictures of both of your carbs at 2.5 turns i could undertand better what do you mean by "1/16th below the nozzle".

10 turns clockwise lowering the jet without puddleling??

Ill take pictures as where it is right now at 3.5 turns so you can guide me

Great picture. At 2.5 turns i should be able to see some fuel over the nozzle after idling for 1 minute?

Could you be able to take some pictures of your carb nozzles at 2.5 turns clockwise? It will really help me a lot as reference.

Mark you are the best. Ill keep working on my float adjustments. Today ill crank the car at 3.5 turns and verify the level. Here i found a picture of how they were adjusted from ztherapy when sent by mail supposedly at 2.5 turns. I noticed the float is not fully straight but inclined.

Mark, At least you clearly understand my car's problem. Spark plugs turning black when idling for long time. Spark plugs turn black and when accelrating engine sputters until the spark plugs clear again.

Ok. I get your point. Do you think that when the psi was at 4 to 4.3 psi it could have affected the car performance in any way?

At least now i know that the carbs can work with 3 psi. I can move on and continue adjusting the floats by narrowing the gap until i reach to 2.5 turns.

At least you understand me and have patience.

Okay. Took the car for a drive at 3.5 turns clockwise. No fuel starvation whatsoever. Good response. Rpm set at 1200 at idle maybe i should lower it to 1100rpm. I have attached pics of plugs 2, 5 and 4 for your opinion on the mixture. Should i lower it to 3?

Valves were adjusted a couple of years ago by a mechanic as per schneider spec sheet attached yesterday.

I havent done a new compression test since 2 years ago. I do have noticed that if i pull the spark plug cable terminals out from each of the spark plugs when the engine is at idle there is an idle drop. The only one that does not affect the idle is spark plug number 4. Is this normal?

Schneider 274f cam requires setting rpm to 1200 at idle? I thought it was 1000 rpm¿¿¿

The car is a sunday car when there is no traffic. However, once you get on stop and go traffic plus heat idle becomes lumpy and tends to fall frrom 1000 rpm to 600.

This is what the PO sent me with the car. Do i really need to spend 2500 in a new engine?

You are the man! Rear and front floats. How much more should i keep bending and not getting fuel pouring from the air vents of the float lids.

Maybe thats the reason the seller sold his car to me. He clearly knew that the engine was not rebuit accordingly.

Okay found a nice small flash light that can help me with your instructions. I was thinking that the 4.25 fuel pressure i had before could have damaged or altered in some way the needle valves and seats and since i had a new set i purchased from amazon, i also decided to replace them. Do you think i will need to check on the mesh filters which are part of the float lids?

Can you take a picture of your carbs without the dome at 2.5 turns so i can at least figure out the 1/16 inch below the nozzle measure. Please be advised that i need to pull the choke out at 2.5 when the engine is cold or else the car stumbles and shuts down.

Do you think that with the specs of my engine and with the schneider 274f cam i will be able to dial both carbs at 2.5 turns? I believe this engine and cam will require more gas.

Almost there!!!

Its the sending supply side.

Ok ill leave that aside as its correct.
