bravemushi260z Posted April 25, 2021 Share #1 Posted April 25, 2021 Hey guys, hope you’re enjoying your Sunday, I’m spending it trying to rebuild the carbs on a 260z that’s been sitting for years. I’m almost done putting everything back together! New plugs, fluids, belt, hoses, my final step is rebuilding the carbs. I took them all apart last night and saw something very weird going on regarding the choke shaft and plates. On one of the carbs, there was no shaft or plates and the holes for the shaft were closed off. On the other one, there was a shaft and no plates. I’m new to carbs but I know this doesn’t make sense, how is the air ratio being controlled if there’s nothing stopping it from entering? I know someone had messed with these things before as well as the fuel lines based on the return lines being made by an 8 year old, but I’m trying to figure out how this car was running and driving like this and trying to find out what to do next. I appreciate all your help and responses! Link to comment Share on other sites More sharing options...

Patcon Posted April 26, 2021 Share #6 Posted April 26, 2021 If the car will start without the chokes, then the main Butterflies is all you really have to have. Sometimes the downdrafts need the chokes but I believe they also have an accelerator pump which could be used instead of a choke Link to comment Share on other sites More sharing options...
