Evaded Posted June 4, 2015 Report Share Posted June 4, 2015 Anyone have detailed pics of the throttle mechanism coming out of the firewall into the stock carb? My throttle sticks bad.. cant figure it out. Maybe I installed it wrong when I put the car back on???? lost. Eric Quote Link to comment
MicroMachinery Posted June 4, 2015 Report Share Posted June 4, 2015 On what? 510's have a mechanical linkage system, while 521's have a cable. 2 Quote Link to comment

datzenmike Posted June 5, 2015 Report Share Posted June 5, 2015 Needs return spring connected. The Red thing... Quote Link to comment
Evaded Posted June 5, 2015 Author Report Share Posted June 5, 2015 I have the spring connected. Maybe its worn out? The spring is pretty worn looking and loose. I may need a stiffer spring. Thanks Eric Quote Link to comment
datzenmike Posted June 6, 2015 Report Share Posted June 6, 2015 Find and fix the problem, stiffer spring isn't likely the fix and will just wear the throttle shaft out. Disconnect the throttle linkage from the carb. Now work the carb... is it stiff? Yes... then the carb is the problem. Accelerator pump jammed? Throttle plate rubbing bore? Foreign object stuck in throttle plate? Carb linkage bent and jammed? No... then it is in the linkage for sure.. 1 Quote Link to comment

Doctor510 Posted June 9, 2015 Report Share Posted June 9, 2015 Get new ones from, http://www.piercemanifolds.com/. Christ, do you want us to go shopping for you too! Quote Link to comment

So if those ball things are shot, whats the solution? Try greasing them. Move around each point until you find what is sticking. In my 68, I found that the pivot that the pedal rod itself moves on was dirty and sticking. I took it out and took it apart, cleaned it, and re greased it. Now it moves silky smooth. 1 Quote Link to comment
datzenmike Posted June 10, 2015 Report Share Posted June 10, 2015 Rebuilding the carb is the same as buying a new part..... there is absolutely no guarantee that it's in working condition. Don't assume. 1 Quote Link to comment
banzai510(hainz) Posted June 10, 2015 Report Share Posted June 10, 2015 I alwasy stripped cars and had sapre ball ends and shafts but went to a cable set up with Dual carbs. but those use the Mikuni ball ens on the carb shafts(got spares of them also) 1 Quote Link to comment

Thank you for the response. Yes Im going to break it all down today and do that, to see if it helps. Rebuilding the carb is the same as buying a new part..... there is absolutely no guarantee that it's in working condition. Don't assume. I understand that. Should have said the carb seemed to function as it should with the linkage disconnected. Thanks for the help again. Get new ones from, http://www.piercemanifolds.com/. Christ, do you want us to go shopping for you too! Thanks for the link.... If your gonna respond that way however Id rather you just not help. I mentioned right from the start when I became a member a couple of months ago, this Datsun was my first and very new to me. I apologized for all my newb questions. Everyone on this site has been very helpful and supportive so far. I alwasy stripped cars and had sapre ball ends and shafts but went to a cable set up with Dual carbs. but those use the Mikuni ball ens on the carb shafts(got spares of them also) Might have to shoot you a pm if the greasing doesnt work.. thanks for the help again. :) Eric Quote Link to comment
