kf6rcp Posted March 10, 2009 Report Share Posted March 10, 2009 I am reposting this since I posted it in the wrong forum. I was wondering if anyone had run to the problem I have with my Datsun. It starts to back fire through the carb and sometimes exhaust and stalls on 3rd or 4th gear. I cleaned carb, new distributor, fuel pump, fuel filter, spark plug wires. I run a MSD ignition with weber carb. I took off the valve cover and noticed the right side (drivers side)on the timing chain seems to be loose. Will this cause my problem? Another thing I notice was the distributor rotor shaft moves/turns around .5 inches and goes back to the original position. Is this normal? Any input will be greatly appreciated. Thanks!

hang_510 Posted March 10, 2009 Report Share Posted March 10, 2009 TC seems normal. points? a bad(worn) shaft could cause your symptoms regardless. did you time it? "yeah its @ ____ *BTDC" Quote Link to comment
banzai510(hainz) Posted March 10, 2009 Report Share Posted March 10, 2009 (edited) try a timming light at idle. see if it WONDERS erractically !!!!!!!!!!!Jumps around. maybe MSD is going out.?????? You know MSDs go to 1 spark after 3 K anyways But I have to go home and ck but I dont think the rotor is to move a half inch.(swap another dizzy if doesnt move 1/2 inch then thats it, Maybe MSD after that. The vacuum adv plate can move. The Rod inside the dizzy is preety much what I remember just a rod and the rotor part slips on 2 prongs that has weights.
