Hey yall , been looking around here for about a month it has inspired me to buy a 620 ! This is my first Datsun so im trying to learn as much as i can this fourm is great . My truck is a 1973 it is in good condtion body wise I just got it to run tonight , the carb didnt work so I had this old retired guy Iknow to rebuild it for me . Here is where it gets good , he said he had never seen a carb like it he says it looks like an industrial carb so i started looking at the 620s at my job (I work at a junkyard) we have four of them a 74 , 76, and two 78s all of those trucks have a valve cover that says Datsun ohc , but mine says Datsun 1600 ? Anyways Im glad to have joined and i will post pics here are 2 crappy cell pics .
