My Vuka 110xl doesn't idle without the choke on. I have cleaned the carburator but after a few weeks it's dirty again. Where do you suggest I start looking for the problem?
The Vuka has been standing for about a year without being started. I removed the petrol filter and it was raw, I threw it away. The gas tank looks dirty so I will have to clean that as well. Another problem, my electric starter doesn't work, but the kickstarter does. Cabling issues?

A bit more info might help; Make, Model, Year, mileage, type of fuel.
Hint............. if it is petrol (gas) with a carb, remove the air filter have someone pump the gas pedal while you look into the throat of the carb. You should see fuel squirt into it.
There are way too many variables and possibles to start theorizing on without more information.

an old trick to remove water is to use methylated spirits in the tank with the petrol
It breaks the surface tension of the water down and allows it to go through the system with no ill affects
say about 3 liters to 50 liter petrol
if no gas will enter priming bulb at all I see only a few possible things for this
(1) gas line broken/melted
(2) filter looks good but has internal plug
(3) primer bulb has a small crack in it (most common )
The main reason why a mower starts up and then cuts off after a short period of time is because of poor air flow to the carburetor and is most likely a blockage somewhere.
First you should try this. Remove gas cap and filter then place a really thick rag over the top of the carb where the filter was and either blow into the gas tank or wrap a rag around a tapered air chuck and then place the air chuck in the gas tank (with rag fitting snug around chuck) blast it a few times and listen for bubbling, if it's bubbles then you have removed the blockage.. Take the carb off of the mower and clean the carb / jets with a thin piece of wire. Be sure to clean the gas tank completely and the fuel line. Check the oil level, some mowers have a low-level oil shut off. Change the plug out with one thst is reccomended for your engine. I wouldn't reccomend running the mower without the filter, that causes dirt and grass debri to enter the carb, fuel line and tank.
This should fix the problem, if it don't you should find a lawn mower repair service.
Without having a look myself i would hazard a guess and say that teh fuel line is perished on teh rubber flexible that connects up with the fuel tank sender unit .Honestly cannot see it being a blocked fuel filter as never changed a petrol filter in 40 years .Diesel filters yes but petrol never only on old old cars with ,metal tanks have i had to clean them out and the gauze filter on the pick up pipe in the tank.
On 2007 Toyota Hiace the petrol fuel filter is integrated in the fuel pump assembly placed inside fuel tank. It's not possible to change the petrol fuel filter without remove the fuel pump out from the tank. The petrol fuel filter is for fuel pump life.
Probably a good idea to change filter. Gas in oil due to attempted starts and flooding. Additives will draw out water and make white smoke. Been there, seen it. New gasahol will separate within 6 months and will draw and accumulate moisture like diesel. Since no default lights are on you could still try autoparts store like Autozone or similar and ask for test but without faults probably a no show. The additives could cause high idle until you are burning 100% gas. Check to see if all vacuum lines are correct after removing air filter.
