What causes gas to pour out of the overflow hose on a new mikuni carb?
It may be caused by a poor needle and seat. The needle or seat may be clogged with debri allowing fuel to continuously flow into the bowl and out the overflow tube. Check this theory by removing bowl, and reinstalling fuel line and carb to engine and allow fuel to flow. Once flow has begun gently push float into the most highest point. Fuel should shut off. If it does not, then you need a new needle and or seat.

Your floats might be stuck.
Can you put a mikuni carb on a john deere 300 snowmobile?
yes, i have done it use the flange from a skidoo and drill the bolt holes out you will need a new throtle cable to match the carb and then just play with the jetting to get it to run right you might need a fuel pump as well the stock carb had a integrated pump that was junk
If the fuel pump on a Chevy S-10 will not stop running and it has sat for two years but has new regulator seals head gasket etc and is fuel injected what could be wrong?
if your engine has a carb and is not fuel injected the fuel pump may be putting out more pressure and volume than the carb can handle. The rush of fuel may push the float down and hold it causing the carb to overflow. This would be a dangerous condition.
What could be causing a 1996 Honda foreman 400 to flood fuel out of the overflow?
I had the same problem. I took the carb. apart, cleaned it and rebuilt it, and that seemed to fix the problem. I suspect some thing had got into the carb and was preventing the fuel intake cut out from closing properly.
What cause your car to idol at full rpms?

What does carb jet size number mean?
The Higher the Jet Number the Bigger the hole init so more fuel goes into engine to make it richer, the smaller = vice versa less fuel means lean running. some carbs a 120 means 1.20 mm diameter but on Mikuni it is lm flow (milliliter) flows. so depends on who makes carb.? but yah bigger is more fuel

What would cause fuel overflow ina a 1984 Honda odyssey fl250?
Take the carb of and see if the carb floats could be filling with fuel and not shutting off the fuel intake to the bowl. Check the floats for liquid inside. If that's not it then check the floats for restricted movement. While your in there clean out the bowl and the float needle that is supposed to shut off the fuel flow to the bowl.
Why when you rev up on a standard transmission car the rpms go down by itself before you release?
The most obvious problem is a fuel issue; specifically the engine isn't getting enough. Check your fuel filter. Check your fuel pump. Check the mixture (carb or injector).
