I've tried a couple of hours to synchronize….

here a pic of the engine (car is stored at the moment i'll get closer ones next week) My problem is that at idle the car runs smooth but very rich in gas (fumes when i press gas). As soon as i put the car in drive…engine runs very high in rpm. I turned the 4 little screws on the carbs…but I just can't find the perfect adjustment...

After a couple of months looking at this forum I decided to finally register. I'm from Quebec, Canada where the Datsuns are….pretty rare! i'm the pround owner of a little 510 that I bought last summer from a guy who imported it from California. I also bought (last week) a 720 witch is coming home and I should get next week. Unfortunately, since it's winter here I will not have the chance to drive it until next summer…. I have some minor problems with the carbs on my 510 (running too rich and very hard on idle) and since we are about 2-3 owners in Quebec, I've decided to come here to get some help. I'm a noob with carbs….but I want to learn….. Oh…and sorry for my english….french is my spoken language on it's way to his new home:
