My name Is Anthony I have a 1971 521 Datsun pick up with an L16 everything is pretty much stock except the carb it came with a 32/36 DGEV Weber carb. I tried rebuilding the carb but I had a lot of issues with the choke so I just saved up and bought a new Weber I installed the Weber and it fired right up I have been learning about tuning and attempting to get it to that sweet spot. I noticed it pops a bit if you hit the high rpms just right. I assume it’s running rich just cause the popping happens often. I also believe the timing is off, when I shut the motor down it still fires a bit here and there yesterday I drove it into town where I work and I went somewhere on my lunch turned off the truck and she fired 8 times so I turn the key back over and it fired up I shut it down and it completely shut down like it should have. I am still new to working on the truck and am just trying to soak up as much knowledge as I can that being said any advice is very much appreciated I can take photos, videos and try to provide better info.
thanks in advance
