- Finished up the carb swap from the stock Hitachi DCH340 to the Weber 32/36 DGEV on the L20B engine. The instructions with all these kits are not 100% accurate, you would need to have previous experience doing one or go slow on each step.
Modifications Done: Swap fuel inlet from right side to left side, reuse throttle cam from old carb, notch throttle cable bracket to move towards firewall, 1/2" NPT intake plugs.
Right after this video I adjusted the fuel mixture screw and idle screws mainly because it ran out of gas in the temp bottle and I only use clear gas (non-ethanol) until its driven more.
Comment if you have done this swap or plan to sometime, Thank you!!!
I worked at the Datsun dealership parts department 73 tru 76 cool little vehicles that rusted out pretty quick in the rust belt.
That is true. Best way to prevent that is take them apart every two years and spray black rust olem on the chassis, floorboards inner fenders, underneath the bed, everywhere and anywhere salt and road chemicals might form along with washing your truck as much as you can wash it to prevent it from rusting completely out.
Love my old 620! 73 with jeep alxe and transfer case, currently running 78 2.0 with 76 5 speed, 2nd gear syncro giving trouble, getting hard to find parts for these old trucks (i know z cars and 510s, snd 810/ Early maxima i think has almost same transmission)
Yes they have the best character imo. I had a 74 620 4x4, they do use Jeep conversion parts back then.
Have diesel 720 also sd22, love me some datsuns! Had 280 zx, wish still had it, might have killed me though...could drive that think insanely hard!
When i had original dual points, they were emissions related, one was retarded for coasting and idle, the other set was normal (advanced) for acceleration (driving). There is some switching relay on carburetor that tells which set to run depending on throttle position, i can't remember whether it was the front or back set of points but just connect both set of leads/feeds to one set of points and it will run way better on one of the points when it is the drive set...
I had the later emissions with dual points before, yanked it out and used the matchbox Dizzy swapped in it. This one is a simple single point setup, no troubles.
Hermosa!
Thank you Juan!!! We have added a couple more hours of tuning the carb and getting rid of the exhaust air injection sounds you hear in the video.... much smoother and quiet.
Can Weber Carbu_ Installed on J15 Datsun 620 4cyl
Yes, the Weber 32/36 will work with an L16 adaptor plate to the J15 motor. Might need some tuning but usually its fine out of the box.
Wish i could put a weber on my 84 720 but have stick with computer controlled hitachi CA emissions bullshit, run like shit, and power like shit, and still shit mpg...
We finished this truck and it's ready to sell, 1975 is Cali smog exempt.
