the carb on my 84 rx7 is cutting out after a bit of use. some tiems it takes a while some times it takes very little time at full throttle. it has been dead for two days this time around. I can not get any fuel into the barrels of the carb. it seems like the float bowls are full to the right level. any ideas?

 

I'd start by checking the fuel pump and fuel filter.

 

Seems? Check to see if theres fuel in the carb or not. Very important to know. Either your not getting fuel to the carb, as Inittab suggests would be a filter or pump problem. Or the carb is not putting fuel into the engine.
