SickLD28

Can someoen please direct me to where I can post my item for sale? I have triple dellorto 40 DHLA Non emission type. Condition: 8/10 Rejetting would be proper for your engine specific. Other than that all the gaskets are new, and if not satisfied I have extra ones. I also have a canon intake manifold and clean k&n air filters.

I agree with you. Anyone have any idea about the air bypass screws?? Does my dellorto 40 DHLA require the screws? I do not see any threads in the holes.

I agree with you. And to answer your question, no they have not been jetted for this engine. I actually bought the carbs used and supposedly "rebuilt", however I can assume the engine I have now is more powerful than what the previous owner was running... Any advise for the correct jetting for my engine?

I have a L28 crate engine with a V07 Diesel Crankshaft. Drag Cam I would say (4000-6000RPM) l24 8mm rods ka24 cast pistons stainless steel valves Triple Dellorto Carbs (40 DHLA Non- Emission) Does this model have a air bypass screw used to adjust for timining along with the fuel mixture screw?? My carbs have been tuned strictly with the fuel mixture screws. I have not adjusted anything else except for the linkages.* LOOK at the PIC BELOW** I have used a Holley Black fuel pump with a holley regulator running at 3-4PSI, and I was running SUPER RICH. I changed the fuel pump out and put a carter pump without a fuel regulator. I ran it with a return though, with a needle valve connected to adjust psi.( I was only able to do slight increases in psi) Even with this change I was still running super rich. However, a hair length decrease of smoke... FYI: the timing, tuning of carbs, and even at the leanest condition of fuel mixture for the carbs I am still blowing out black smoke. Mechanics have suggested that my cam is a drag cam, and therefore the engine loves the richness of the fuel, which is why I cannot get rid of the black smoke... Another mechanic suggested that my idle jets are off... I have even adjusted my float levels on all carbs, and they are all at good levels. Not to mention redoing the timing multiple times. Also adjusted all the lashes. ( does anyone have recommendations on the measurement of lashes?) exhaust and intake.. Can anyone point me in the right direction to cause this richness in fuel? I am literally smoking black smoke every where I go.

http://i567.photobucket.com/albums/ss115/squannn/photo3.jpg My bad about calling it a Ld28, it just has a diesel crank, but yes it does run regular gas. I changed the fuel pump to a Carter 4600Hp, a low PSI pump. With this setup I also took off the regulator, and ran a return line with a needle valve to control the amount of return. Despite this, I am still running rich, blowing out black smoke. I have adjusted the carbs to the leanest condition, and it shows no change in richness. I even looked into every barrel to ensure none of them were dripping. They all spray evenly. My guess to what the problem is that my jets, idle jets are the wrong size. I also realized that I was missing the air bleed screws on every carb.

Hello peeps, my LD28 with triple dellorto's is brand new with less than 30 miles, sychronized, and sounds amazing. I have made sure that the timing is on point at 10. I have a holley black fuel pump with a fuel pressure regulator, at 3-4psi. Despite the above, i am blowing out black smoke even at the leanest tuning on the carbs. I've even switched the fuel pump to a carter 4600hp and took out the fuel pressure regulator, and it still blows out foul. Not to mention I even changed my fuel filter, aligned the oil pump and the punch mark, aligned the distribuor at 11:25 oclock. My only guesses to my problem are: my carbs are used, but looked in good condition. But, I think I am missing the air bypass screws on all carbs. The fuel mixture screws are there and even when i tune them to the leanest condition, there is still so much black smoke. I'm new to forums, and desperate for help, advice, or anything that can point me in the right direction. This is the build i have: Datsun 3.0 Liter Stroker Long Block Engine.
