68Datsun510 Posted April 30, 2011 Report Share Posted April 30, 2011 A few basics to check, fuel in the bowl? fuel pump moving fuel? Vacuum leaks? all carb base nuts tight? Quote Link to comment
bilzbobaggins Posted April 30, 2011 Report Share Posted April 30, 2011 Could have sucked some funk outta the bottom of the fuel tank. Have you tried getting out on the road and opening it wide open? Suck the b.s. thru. jeff Quote Link to comment
metalmonkey47 Posted April 30, 2011 Report Share Posted April 30, 2011 Dang, I opened this thread expecting to see someone jumping their Datsun! I am dissapointed. Datsunkid, sounds like you may have sucked some stuff out of the bottom of the tank. Anytime I hear of someone running an old tank like that empty, I usually recommend a new fuel filter and a quick inspection. As old as these cars are, you have to be careful not to run the tank empty, because any sediment that's settled in the bottom of the tank is sucked into the fuel pickup. Usually the filter does a pretty good job of catching it all, but sometimes a little makes it by. Quote Link to comment
datzenmike Posted April 30, 2011 Report Share Posted April 30, 2011 The filter does an amazing job but water can flow through. If it's just water it will slowly get sucked through or evaporate from the engine warmth. Definitely change the filter, and cut it open and inspect. I had problems once and when I shook the old filter it rattled. The element inside had come apart and wasn't filtering at all. $5 for good running is cheap. Quote Link to comment
The datsun kid Posted April 30, 2011 Author Report Share Posted April 30, 2011 i changed the filter right after i didnt think to check it though could i just run it with the choke on if it runs better until i figure it out? Quote Link to comment
datzenmike Posted April 30, 2011 Report Share Posted April 30, 2011 Sure, but eventually you may need to pull the carb and clean it. Quote Link to comment
The datsun kid Posted April 30, 2011 Author Report Share Posted April 30, 2011 im planning on it i just have a bunch of stuff to do the next couple of days and i wont have time to clean it Quote Link to comment
