Mikuni 38 carb question
Posted: Sat Sep 01, 2018 9:30 pm
This begins by me having a strange, intermittent running issue. Basically it felt like the engine just wasn't getting enough gas - it would idle fine, but the engine would not spin up quickly at all. From a stoplight, it took lots of gas and clutch feathering. The engine did not like a load. Once it was moving, it was lethargic, but every once in a while I'd get a 1-second reminder of how it should be. Like "blah blah blah WHEE blah blah"
So I drained the gas (thinking water had accumulated), replaced the fuel lines, and has the carb cleaned. Upon putting it back together, it appears one carb is leaking gas profusely from a small hole on the front side (under the bowl?) I'll try to attach a pic. There's a screw associated with the hole; I wonder if it wasn't something the shop left open? Does that screw close the hole, and should I tighten it? I know carbs work by science and dark magick - mostly dark magick - and that's about as much as I dare mess with it.
Is this an overflow? Am I getting too much gas to the carb? I did have to replace the Y in the fuel line that splits between the carbs and the tank. I couldn't find a Y fitting, and opted for a T fitting. (The fuel goes straight through the top of the T to the carbs)
I know diagnosing stuff via the internet is a little crazy, but I'm hoping this is just one of those "well DUH" things.
