SOURCE: I have a 2008 zip 50 4t. It runs well in idle. But

Juergen, FixYa sent me a notice that you want my opinion. The answer Mr. Ginting gave is correct. However, the main jet is brass and deterioration should not be a noticeable concern.

Toro Grandstand with Kawasaki FS541V engine runs in idle but dies when throttled up and will not run at full throttle.


lack of fuel is the problem
could be blocked main jet ( most likely)
in tank filter could be blocked (part of the tap if screwed directly into tank)
tap corroded inside preventing full fuel flow
needle and seat obstruction restricting fuel flow

Briggs Stratton 5hp I/C starts ok, runs, but will not rev


My money is on a partial blockage of the main jet or the passageway to it. You're having to force it to run through the idle jet by fully choking the incoming air. There's not enough gas coming in with the choke open to allow it to run.

I'm thiniking total carb disassembly, carb cleaner and an air compressor combined with a ton of patience will take care of the issue.

Starts & runs for about 25mins stops & wont start leave it a while & it will start & do the same thing again


This is likely to be a fuel starvation problem.
Fuel is fed from a reservoir called the float bowl. This works pretty much like a toilet cistern with a float to cut off flow once it fills. Once the bowl empties and doesn't refill due to a blockage, the engine will cut out.
Clamp off the fuel line or turn off the fuel tap. Remove the bowl, unclamp the line or turn on the tap, and check fuel flows freely. If it doesn't, there is a blockage in the fuel line which you need to trace.


Another scenario is that the main fuel jet is blocked or semi-blocked. This can cause the engine to run ok when idling (since the idle jet is ok and not much fuel is required), but cut out as you throttle up. This is because more air is sucked in, but not enough fuel is drawn from the main jet due to the blockage. So the mixture is to weak and the engine stalls. The jet can be cleaned with compressed air or ideally a carburetor cleaning aerosol.

My 2004 Vulcan Classic 1500 won't idle.


is the carb jetted? if so check to make sure it has the right size jets. too small of jets starve the engine of fuel, and too large flood it. also there should be 2 jets one main jet which controls the amount of fuel when at 1/4 throttle to fuel throttle and then there should be a second which would be the pilot jet that controls idle mixture (1/4 throttle and less) it's longer and thinner than the main jet with multiple holes for mixing air and fuel for idle. have them to make sure the jetting is correct. Also IF the engine had been bored you will need to use larger jets for the added volume in the cylinder chamber from the boring. aftermarket exhausts will also cause the engine to be rejetted but usually the sellers will have charts telling you what jets to run with the exhaust.

Hi, Jamie it should be noted that your performance issues are not electrical ie. faulty charging system, battery condition, and connections etc. If your fuel system (gas tank, filters, fuel valve and carburetor) is contaminated with ethanol sludge, varnish, rust, dirt, water etc. or your bike has been sitting for months or years without running these components must be "PROPERLY" cleaned and reassembled "CORRECTLY" before any adjustments can be made. Tuning your carburetor is fairly simple once you understand the basic principals. You engine is a simple airbox sucking air in and blowing it out, it is finely tuned at the factory for maximum performance once you upset that delicate balance by changing air filters, camshafts or exhaust systems your performance may go down the and the engine may run poorly, you need to compensate the air-fuel mixture in the carburetor in order for the engine to run smoothly and at peak performance. If you are running multi carburetors you need to sync them first and make sure your air cleaner element is clean and dry for paper elements or lightly oiled for foam and meshed elements and properly installed. Here is how and where you compensate trouble: "TIP" if your engine "BOGS" your not getting enough fuel.
1. Closed to 1/8 throttle is managed by the air screw and pilot/slow jet.
2. 1/8 to 1/4 throttle is managed by the air-screw, pilot/slow jet, and throttle slide.
3. 1/4 to 1/2 throttle is managed by the throttle slide and jet needle.
4. 1/2 to 3/4 throttle is managed by the jet needle, needle jet, main jet, and air jet.
5. 3/4 to wide open throttle is managed by the main jet and air jet.
6. Wide open throttle is managed by the main jet.
If you are running lean, spark plug electrode color is white, engine runs hot and feels like it is starving for fuel you need to go up on the jet size or move the c-clip down one notch. If you are running rich, spark plug color is black or dark gray, engine runs cool, and bogs down when accelerating you need to go down on jet size or move the c-clip up one notch. When your carburetor is properly tuned for maximum performance your spark plug electrode will be a light tan color like coffee with cream. If you prefer fuel economy over performance you can go down on main jet sizes until a satisfactory level of lower performance is acceptable versus MPH, your spark plug color will be whiter and your engine will run warmer. These tuning adjustments will only make improvements if your intake and exhaust system have no air leaks or sealing issues and the entire electrical system is in proper working order and you have no mechanical issues.

1963 vw newly rebuilt engine, starts then dies at RPM acceleration


Could be one or both of two things.

1. The accelerator pump in the carb is clogged, the linkage is unhooked, or the diaphram in the pump is bad. It's cheap to replace and comes in the carb rebuild kit. This usually just causes hesitation when you step on the gas pedal. It doesn't usually cause the engine to stop running.

2. More likely is that the main jet in the carb is clogged. At idle, high vacuum under the closed throttle plate in the carb causes fuel to flow thru the idle jet. As the throttle plate opens (as you step on the pedal), the vacuum under the plate dissipates, stopping the flow of fuel thru the idle jet, and the vacuum ABOVE the throttle plate increases, which is supposed to then draw fuel from the carb bowl thru the main jet in the carb. If the main jet is clogged with dirt, then it can idle just fine and die as soon as you step on the pedal.

High rpm problem after bad gas will not rev.i messed with the jet setting and made it worse


Assuming that the bad fuel has been cleaned away, check the fuel filter, air cleaner, and muffler for plugging. Turn both jet screws CW to stops (lightly) then back out CCW 1-1/2 turns each. This is a basic setting which should allow the engine to start and warm up. After warm, pull the throttle full on and turn the H jet needle CW until the engine starts to speed up. Final adjustment is when the engine 4-strokes at speed unloaded, but immediately 2-strokes when cutting. Release the throttle and adjust L jet needle CW until the engine idles fairly well, but still allows the engine to 'follow the throttle'. Hope this helps!
