Under hood fuel lines, touching coolant or heater hoses. Fuel lines under vehicle close to or not shielded from exhaust pipe, converter, muffler. Fuel lines pinched or crushed. Fuel filter changed recently. Fuel pump pressure.Fuel pressure regulator & Fuel pressure sensor.
The age of your vehicle also guarantee's a vacuum leak. It may sound silly but the truth is rubber grommets, and hose's shrink and dry out over time and the harsh environment under the hood makes it worse. Check all vacuum lines and fittings attached to the intake manifold, valve covers (pcv valve), and be sure to check for a vacuum fitting on top of the intake just behind the throttle body. Does it fit tight in the hole? You can seal loose fittings with a high-temp RTV (Red) silicone sealant/adhesive. Several small leaks add up and your engine, heat/AC, and transmission will be all to glad to tell you about it.
Aside from that, if you are still having problems, Have a look at the MAP & Oxygen sensors. Finally, you may end up replacing the TBI throttle body assembly.
There could well be a build up of sediment and debris in the main jet to the carburetor. It is easy to get to and clean. It is the brass bolt that holds the lower float bowl onto the main body of the carburetor. To clean it, drain your gas. Remove the bolt and external washer UNDER the carburetor bowl. Clean out the bowl of any sediment and/or water. To clean the brass bolt, use no metal objects. Carb/Choke aerosol spray cleaner will do the job. Pay close attention to the hole in the bottom of the bolt and the very small holes about 2/3 of the way up the bolt. Clean till shiny with holes cleared and reinstall. Your fuel flow problem and shut off condition may be solved.
Thank you for the inquiry.
This sounds like the classic problem we all have after storing our bikes all winter. The gas tends to shellac up and leave residue in the carburetor, jets, sediment bowls, and filters. Suggest draining your gas (use it for your lawnmower) and replacing with fresh higher octane premium gas. There are some fuel additives that clean quite. Try one of those. Change your fuel filter. You may also have to remove the carburetors sediment bowls and clean the shellac out of the pilot jet, normally not necessary. If you haven't had a tune up for a while that would also be a good idea.
I have Aquaguard Nova from Eureka Forbes. Presently, on switching-on the water there is only beep sound for some time and then it stops. This is no music. What can be the problem? Is the water still filtered properly?
On the top of the head is pressure which is depressed to relieve the pressure off housing. Inside the head ( when you unscrew the bowl) is a screw, spring and small o-ring as part of the pressure relief button. First see if the screw is loose and tighten. If not you can take this apart, inspect and repair as needed. RJ
I always replace the air filter if its a paper element, and even if its a foam element I replace it rather than clean it. That said, engine stumbling is rarely and air flow problem - but it could be, so having a new filter assures no air restrictions.
I would drop the carbuerator bowl. On the bottom of the carb, near where the fuel line comes into the engine, should be a nut. Removing this nut allows the bowl to drop off the carb. Some engines the bowl screws off, you will have to look at the bowl. Often the bowl has sediment or sludge buildup inside. Cleaning the bottom of the bowl can prevent that sludge/sediment from plugging the intake tube. Even on newer mower models this is a common problem, the gas line tubing interior breaks down and the inside of the tubing can start degrading - ending up in the bowl as sludge.
After cleaning the bowl, I would add one ounce of fuel line cleaner to a full tank of fuel and run the entire tank of fuel. This will clean any deposits or "varnish" from the interior carb parts. Doing this and the first step will assure your carb is clean and functioning.
If that doesn't help, then I would look at the spacing between the magneto and coil assembly. If you want to do that I'd like you to write down all the model numbers and serial numbers on the engine nameplate, that way I can give you specific directions.
