Need more air - jetting
Posted: Mon Dec 26, 2022 9:29 pm
Hello all,
Just got my 87' elite 50S running after years of sitting. I've had this baby since I was 19 (I'm 32 now) and it has a lot of sentimental value, so I'm finally restoring it.
The issue I'm having is air/fuel ratio related. I've had to totally remove my air screw on the carb for it to run correctly, but I don't want to leave that port open and potentially pull in dirt. It seems I don't have the right jet installed. Years ago I ordered a carb rebuild kit and have no idea of the correct size main jet that I need. Everything else is stock, but I have replaced the bystarter and installed new piston/rings. Just flushed the oil system with Honda Pro GN2. Like I mentioned, it's running fairly well, however it won't idle unless the idle screw is all the way in, which causes it to idle a little too high - higher than in the past when everything was working as it should. Even a quarter turn causes it to die. I'm fairly confident jetting is the issue, but wanted to get some expert opinions on what y'all might think could be the cause. Thanks in advance!
