OK i have an 82 rx7 i just recently adjusted the floats to stop a flooding problem which worked but know im not getting hardly anyfuel just a few drops when i put the gas to the floor...im wondering if this is the vacumm lines maybe or what hers are some pics of the carb with missing vacumm lines circled..thx

 

Vacuum lines do not cause a lack of fuel. In pic 1, connect those 2. For now, cap the other ones off and download the carb manual from the link is my sig line.

 

Check the fuel level in the float bowls by looking at the glass- fuel should be half way up. If not, floats are not adjusted correctly.

Has the carb recently been rebuilt? If so, the needle valve may have been sticking and causing flooding. Gunk in the carb from a dirty tank where the car has been sitting for a long time wil also cause needle valves to stick. Another common cause of flooding is inoperative air (bowl) vent solenid.

Search- there's lots of posts on these issues...

well the gas is all the way up but even so would that cause it not to pump gas? is there some knid of plunger i tried reading the carb manual posted above but i havent finished yet i really dont know what else it could be if ne one has ne idea plz let me know

 

Yes, the Nikki has an accelerator pump. Diaphram could be busted or the linkage could be connected wrong. Car should crank & run without this operational, though. The A/P gives it a squirt of fuel when accelerating hard.

If the ap gasket fails, you should see an external fuel drip from it. The ap is feed from the rear fuel bowl. If that bowl is not filling with fuel, no ap squirt.

You might want to remove the had fuel lines from the top of the carb and check the filter screens around the banjo bolts.

 

check the fuel pump and the fuel filter.
