Yes you are right banzai510(hainz), your video and manuals helped a lot. Thank you very much.

With a lot of help from you guys, and especially Doctor510 who have helped me a lot by emailing me, the engine now runs! It was the firing order that needed to be sorted. And immediately a new problem appeared. It will not stop! Even with ignition off, key out and battery negative terminal disconnected, it runs. Oh well.

Thanks, I will check. You are absolutely right. It is not problems, it is opportunities to gain knowledge. :thumbup:

Thank you all for your replies. I really appreciate your help. Every time I buy a new car I try to find a good community around the model, at it seems that I have just found the best here at Ratsun. :) It is good that you ask these questions. The adapter plate seems to be missing and I would not have noticed this if you did not ask the question. It is currently mounted on top of the intake without adapter plate. I will investigate this. Do you have pictures of your installation that I can use as a reference? Around #3 it is a manual choke cable. It would probably be best to have a manual choke carburetor, but if it can be solved by just connecting a wire it is not a big problem. #1 and #2 is now plugged with bolts I took from the L13 intake. No, I do not know if the previous owner took the engine apart unfortunately. Thank you very much for the information. Based on yours and Lockleaf's reply, incorrect timing is likely. Leaks due to faulty carburetor install is also likely. How is the vacuum system on these engines? Is it the only hose I mentioned in the first post? The YB wire do not have 12v when the key is in position 2. This can however be related to a blown fuse or something. It goes in the same sock as the coil negative to distributor wire, and by using a multi meter I can trace it to the fuse box (wiper fuse). I will take out the temp gauge and see if I can trace it here also. Since it ends up in the same place as the distributor I think it should be connected to something placed near this, and the temp sensor sounds likely. Thanks. I do have the stock carburetors from L13 and L18 and I will investigate if the linkage can be used. Hope so. This got me worried. To sum things up it looks like I have numerous problems. 1. Knowledge. I have to get a service manual and gain more knowledge around these engines. 2. Timing. It needs to be sorted. At TDC rotor points at 1. Then the order is 342. 3. Carburetor. Adapter plate missing. Possible more air leaks. 4. Throttle linkage. This can probably be solved by using parts from the old carburetors. 5. Choke. I have manual choke cable, the L13 carb have manual choke, L18 and Weber carb are electric. Is it really as simple as just wire it up?

Thank you very much for your reply KING RAT. I will investigate the mystery of the YB wire a bit later. I sealed the two holes on the intake and tried to crank it again. This time white smoke pops up of the carburetor at the same intervals while cranking. Also oil comes out as you can see on the cam cover and carburetor. The carb was perfectly clean before I cranked it. This can't be good?

Hi, This is the first time i post in this forum and I need some help from you to get my engine running. First things first, let me introduce myself. My name is Thomas and I live in Oslo, Norway. I bought a 70 Datsun 510 4-door as a not finished project some weeks ago. Here it is in my garage. It had a L13 engine from the factory but the previous owner have swapped to a L18 from a 83 Datsun 720 Pickup, but this does not start. A Weber 32/36 is also fitted as you can see in this picture. I do not have any experience with engines of this age so I have to apologize for all the questions. Anyway, the starter motor turns the engine fine, and I have spark at the plugs and petrol in the carburetor. However the petrol ignites, it pops and flames sticks out of the carburetor. The vacuum pump does not have any power. How should this be wired? Live when key is in position 2? And does anyone know where I should connect the yellow (black stripe) wire seen at top of the picture? The other end of the vacuum hose is connected under the carburetor, here: In this picture the electric choke can also be seen. Am I correct that this should be live when key is in position 2? Moving to the back side of the engine. Number 1 and 2 are not connected to anything (I have plugged no 1). Can I plug them both? If not, what are they for and where should they go? And finally, the throttle (3) does obviously not fit the carburetor. Is there a conversion kit available for the Weber 32/36? Anything else I should consider checking? Again, sorry for all the noob questions. I appreciate all the help I can get to get this engine running.
