dash Posted February 4, 2011 Report Share Posted February 4, 2011 hay guys i got a 1979 620 that needs lots of help and iv been reeding the forums for the past cupple of weeks trying to and figure out whats been going on with my little datsun. i figured out that i need a timing chain kit because im short a chain tencher and theres a few other things wrong with the truck. But its a 5 speed and it is slow to take off and i need some help bring it back to life ... Quote Link to comment
Wide14u Posted February 4, 2011 Report Share Posted February 4, 2011 welcome to ratsun do you hear the chain hitting the cover im not sure what you are saying Quote Link to comment
dash Posted February 4, 2011 Author Report Share Posted February 4, 2011 no its not hiting any thing. its just skipping teath and is putting the motor out of time cuz the chain isnt tight and im worred its going to mess up the motor. it makes some noise kinda like a clicking but i know its the chain Quote Link to comment
dash Posted February 4, 2011 Author Report Share Posted February 4, 2011 So im missng the tenchener to keep the timing chain tight ... also the truck moves like a slug its acting like it has no power at all on take off . I have 32/36 webber carb on it now what should I do Quote Link to comment
asdfman7 Posted February 5, 2011 Report Share Posted February 5, 2011 Are you 100% sure your missing the tensioner? Have you taken the timing cover off? It sounds like you may have other issues. I'm fairly new my self and don't claim to be a mechanic of any sorts but if you were missing the tensioner I would think that you would be able to hear it slapping around and would cause you more problems than just slow accel. How long has it been since it has had a tune up? New plugs (correct gap), cap, rotor, points if you have them? Like I said I'm no mechanic, just tryin to help. Quote Link to comment
Skib Posted February 5, 2011 Report Share Posted February 5, 2011 the chain would be slapping all over the place if you where missing your tensioner. it wouldnt hurt to replace your timing set tho, esp if its loose enough to skip teeth :rofl: have you set your valve clearances?

77bullet Posted February 5, 2011 Report Share Posted February 5, 2011 I have two tailgates. oh wait, sorry, i just realized you were in oregon. idk it would prob be cheaper to find one closer then to do shipping. Quote Link to comment
skunk Posted February 5, 2011 Report Share Posted February 5, 2011 i have never been to the junkyards i roseburg, but i know the yards in Eugene have more then a few 620s, lots of parts to be found. its a bit of a trip but could be worth it for you, send me a pm if your going to go. ill let you know what yards have Datsun and what ones dont.
