Hi there. i have a kubota na 600 generator. the problem is there's is no fuel getting into the cylinder. there is fuel in the carb bowl and if i put fuel down the cylinder head via the spark plug hole it runs for a few seconds then cuts out. i've took the carb appart and cleaned it all then put it back together and still get the same results. it will keep running if i spray fuel via an atomiser through the air intake. is there a workshop manual i can download for this generator? any help would be much appreciated thanks

The primer is sucking air, hose leaking or primer bad, When you start it and it starts to shut off, pump the primer and it will keep it running, Then you know I,am right. !!!!!!

When you say you took carb apart did you put a new rebuild kit in it? If not there is your problem. The fuel eats over time the seals an they leak. There is only one fix to rebuild it or get a new carb. These kits are very cheap an easy to do. Just make sure you clean out all the orifices with something like a brass or steel bristle from a brush. Being careful not to enlarge the holes. When you remove the bowl on the carb if it has one. Be sure not to lose the springs an clean out the jets under the float. The kit for each engine is different. Use all the parts, dont skimp thinking this one is ok. Be sure to replace fuel lines at this time they get holes an cracks on them an cause all sorts of problems. This is an easy job. Your engine is sucking air, not fuel. Be sure to check to make sure passage to the engine is not clogges with somthing.

SOURCE: Spark but no fuel . coleman Powermate 6250

if it's flooding the float may have a tiny hole which makes it not float as well and too much fuel will stall the engine...If it's not getting enough fuel to keep running then its usually because of a small piece of dirt blocking a hole..under the carb there should be a brass bolt...take that off and check that the two side holes are clear...then check the center orifice and blow it out...there is also a tiny little hole up near where the threads start...use a wire from a wire brush to make sure its clean....also clean out the bowl and then reassemble...this works 90% of the time for me

SOURCE: Generator not running

This sounds like a jet is plugged, if fuel is getting into the bowl. You need to take apart and blow out all of the jets. (The secret on the adjustment screws is BEFORE ANYTHING, measure EXACTLY how many turns clockwise, until the screw (jet) bottoms out. Then you can get back to an adjustment that is at least close, when you're done blowing everything out.) Pull the carb, use spray carb cleaner and blow all passageways out... remove any particulate matter you find....
While there, also clean the inlet (float) valve, but now with cleaner, if it is a rubber looking seal area. You just want no chunks of foreign material.

I have a briggs and straton1150 seris 250 ohv wont start no gas to the cylinder

Take the bowl off the carb and make sure the float allows fuel to fill the bowl when the float is in the down position. If not you have to remove the needle from the float and use a thin wire go up in the seat to unclog it. If it is getting fuel to the bowl you have to clean the center jet inside where the bowl nut screws in to and make sure the bowl nut hole is clean. The bowl nut also should usually has a hole in the side of the threads which should be cleaned.

I have a eu2000i honda generator that will not start. It is getting spark and will fire when I put a little gas in the cylinder. It is obviously not getting gas, but I don't know what to do about

needle valve stuck.on the bottom of the carb there is a bolt holding the bowl. inside there is a needle valve attached to the float. hondas have a spring loaded rubber tipped needle valve and tends to get stuck in storage(unless it is left empty this will happen almost every time) check seals on bolt and bowl before re installing .

60 psi in a 4 cylinders and fuel won't get to carb

Regarding compression, your valves may need adjustment. Since compression is even across cylinders I doubt the rings are at fault here. As far as the bowls are concerned, your needle valves may be stuck closed. Tapping on the fuel bowls with a screwdriver handle a few times usually loosens them up and allows fuel to flow again. If not then you may need to check your petcock again as it may be clogged.

Float bowl drain plug stripped, had to buy a new carb. new carb came and new float bowl didn't have the threaded part that what may be the ignition module to screw into. So I took the old float bowl off...

When you replace the carbs on these motors it can take a bit of time for them to start and run. If there is a primer bulb pump it up and keep pumping, this is basicly force feeding the carb until it has the vacumn to get the regular supply of fuel coming in.

Wont keep running after start button is released

If the fuel filter is good and lines are good then it sounds like the fuel is making its way to the carb built trash is stopping the fuel from getting into the engine in order to run. Clean out the carb bowl and clean out the valve stem. I know on the Honda unit the valve stem is removed with the carb bowl then then with a striaght screw driver you can remove the Body once you drop the bowl down with the stem so to clean out the cyclinderical body. Good luck

No gas getting to cylinder on coleman 1850 generator

I have never worked on this specific model but I am sure it has a fuel filter that would be where to start. If it doesn't have a filter install one. Also if no filter disconect the fuel line at the carb. and see if there is fuel. It should allow fuel to freely flow out of it so becareful. Also make sure the fuel shut off valve is open. If there is no fuel coming out of the line at the carb you have a clogged line and need to clean the tank and line to remove the clogg. If you do have fuel the carb is your problem and will need to take apart and clean.
Have a great evening

My troy-Bilt 5550 watt generator will not start

First drain the fuel bowl. Any old fuel in there will keep it from starting. Fuel stabilizer is not what it's it cracked up to be. I've worked for 6yrs at a rental yard and had no luck with any fuel stabilizer, the fuel still went bad. If after you drain the fuel bowl it still will not start, you will need to clean the carb. Remove the carb and spray carb cleaner through all the accessible passages. If this does not do it, you will need to replace the carb. For long term storage I highly recommend draining all the fuel and filling just the carb with fuel stabilizer to keep gaskets moist. Then drain the carb when you take it out of storage.

Petrol in crankcase

  • The only way petrol can get into the crankcase is through the carbs and then into the cylinder and past the rings.
  • Drain the gearbox and put in some fresh oil.
  • Turn the fuel petcock to OFF.
  • Drain the carbs then remove the water trap bowl from the petcock. Does some fuel still get past the petcock valve? Replace the petcock if it does. If the petcock is working properly then remount the bowl.
  • From this point forward, ALWAYS shut the gas off when the bike is not running.
  • Please rate this solution as a " FixYa ". Thanks!
