Sticky fuel pin

Was having probs with lean running gen so took carb apart and cleaned and adjusted float level up. When testing float and pin operation noticed that pin didnt always free fall with gravity..needed a little shake. Made sure pin was clean and q tipped seat. Is that a problem or does it need fuel flow as lube to keep the pin moving freely.

By pin I am guessing you are describing the needle? Some carbs have a small tang on the float that connects the needle to the float with a small wire spring while others just push against each other. I would take the carb off the engine and hook up a fuel hose with a small bottle that is higher than the carb and with the bowl off manipulate the float up and down and be sure the fuel flows freely when the float drops and frees the needle. If this does not happen-try more cleaning but a new carb may be necessary.

2003 yz450f running too lean


First, try to avoid ethanol. It melts carb lines, and can goo up small passageways. Get some good gas and try again. Hi test if necessary. Check your specs, maybe the bike requires hi test.
Taking apart and cleaning involves soaking in fresh carb solvent to clean the small passageways. Is there an air cleaner? It may be clogged, test with it off.

Automatic governor speed control, no adjustment. Remove & clean spark plug. Remove air cleaner, replace filter if dirty. Check oil level. Remove float bowl from bottom of carb. ensure float hangs freely and gas flows. Push up on float, gas should stop. Remove pin holding float in mount, remove float and meter needle. Clean meter needle passage with small wire. Replace float and meter needle as require. Observe float bowl screw, see if a hole is present thru screw near head, clean with wire. Reassemble. prime, pull rope 4 times 1/2 way. Pull rope up to 10 times to start. ensure fresh gas. Always use Stabile in gas. Spray outside of carb with carb cleaner to ensure choke is free to operate where cable is attached.

To much fuel! Boggs out! crimp fuel lin e to starve engine of gas and runs great?


Either the float level is too high or there is debris in the float needle seat. This causes the carb to overflow while running. The fix is:
- Remove the main fuel line with the fuel selector off of you have one.... or pull the line and plug it off / keep the end above the fuel tank then
- Remove the float bowl from the carb.
- Pull the float pin and remove the float and float needle (INSPECT float needle rubber tip for damage or dirt... any damage replace float needle and seat.)
- Spray carb cleaner into the main fuel supply hose / manfold fitting on the carb. Your removing any debris that night be in the float needle seat area
- Spray carb cleaner in all open fuel jet passages without dis-assembly of the carb.
- Reinstall the float needle and float (Float pin too!)
BRIEFLY reconnect the main fuel line
GENTLY lift the float to level.... (Incoming fuel flow MUST stop) Lower float.. (fuel must flow)
If the fuel flow does not stop with the float level.. you must replace the float needle snd seat. After needle and seat replacement if fuel still does not stop with the float level the tab where the float needle is will have to be bent UP no more than 0.010 at a time and then re-test flor fuel stoppage with float level. Adjust tab as necessary to get the float level correct.
- re-assemble carb
- test... running and static.

My 97 classic is smoking at idol, and dumping fuel. Carb has been cleaned and the needleand jets have been changed (we even tried smaller ones). It is dumping too much fuel. When we adjust it, it either...


A plugged Idle Jet will give you an erratic idle (up,down,up,down) and also draw in liquid fuel instead of vapor. The 'O' Ring between the float valve seat and carburetor body and the Float Valve are the only two places the fuel may enter the fuel bowl. If the 'O' Ring or Float Vale is leaking the float cannot regulate the fuel level. To test a fuel pump you will need to test for Pressure and Volume.

My suzuki gs400 keeps overflowing with gas from the breather tube! the carbs have been checked and this keeps hapenning?


This still sounds like a carb issue to me. 2 likely causes are incorrect float height and, most likely of all, a sticky float needle. Did you get a dealer to do the work? If so, have a go yourself, its not difficult if you take your time.
First, try gently tapping the carb float bowl, this may (but not always!) stop the overflow and clearly indicates a sticky float needle. You need to remove the carb that overflows (or both). Remove the float bowl (usually four little screws). Looking at the bottom of the carb, you will see the float assembly. This works just like a 'toilet'. As the float bowl fills, the float rises and eventually shuts the float valve (which stops the fuel flow from the tank). Remove the float assembly (normally held in place with a pin). Under the 'tang' on the float will be the float needle. It will tip out easily. Check its condition. Also check the float seat. Make sure both are clean, unmarked and spotless.
Be very careful how you take the carb apart, it is a cast assembly and not very strong.
If the float level is incorrect, then you need to adjust the 'tang' on the float assembly to adjust this. You need a manual to do this Im afraid for the method/mesurement to set the float to the correct height.
Good luck!

I have a John Deere LT133 w/13hp Kohler motor. Problem


I had the same mower in my shop with the same prob. Last week, here is what i did to correct the problem, take the fuel line apart at the fuel filter, open the fuel cap and drain the gas from the tank, once it stops i took couple old walmart bags and compressed air to slowly blow air in to the tank to blow the residue and trash out of the fuel tank. Next using compressed air to blow through the fuel line from where the filter was toward the carb. Next unbolt the carb and remove the fuel bowl, take the small pin holding the float out and slowly remove the float pulling strait up as the needle will be attached via a small channel on the float. There is where you will find the seat which the needle you extracted sets in to stop or allow the fuel to flow. Clean these parts and area WELL. i usually take the air screws out and use carb cleaner to clean those areas as well. Reinstall the needle and float, pin assembly and the bowl. Reinstall the carb , and make SURE to install a new fuel filter not exceeding the last filters micron flow, double check all connections, clamps, and hardware, add new FRESH gasoline with no less than 89 octane at any time, engine should fire and run as intended.

1979 sierra grande runs too righ even after adjusting carb


You may have an internal carb gasket leak or your floats may be adjusted too high.After you run the truck look into the carb to see if there is gas still dripping into the carb bore.Also after running with engine on remove the front fuel level check screw. (have lots of rags under to catch fuel) Fuel level should be right below hole.If it is spilling out it is too high.Floats need to be adjusted up for fuel level to go down.

I have an older mercury 4hp 2 cyl. Wont run. got lots of spark, gas was running out of carb, took it off, cleaned it out, but I might have the spring on the float in wrong. does anyone have a scematic?


Ok, if you have fuel coming out of the throat of the carb then you need to readjust the float level. On that engine the best way to set the float level is to remove the carb. Remove the fuel bowl. Turn the carb upside down so the float is on top of the carb. You want to bend the tang (the piece that seats the inlet needle) so that if you are looking at the float it sits perfectly level. Once you reinstall the bowl and carb be sure to adjust your idle mixture and try it again. If it still spews out of the carb throat then take it back apart and do it again. If the inlet needle point is worn at all then you need to replace it so that it seats good. But if you set the float it is level when the carb is upside down you should not have a problem. You can put your faith in the fact that every spring I rebuild about 5 outboard carbs a day from people letting fuel sit during the winter.
