Lawnmower sat up for a season would not crank replaced sparkplugs air filter fuel filter hose fuel pump is pumping gas to carburator but still will not start unless you pour some gas into the carburator or spray some carb cleaner into the carburator but will not stay running as if it is not getting any gas what should i check next?

engines don't "pull" fuel to carb , it either gravity flows (tank over top carb) there or its pumped there , I do believe the kohler engines from 8 hp thru 25 hp use a vacuum activated fuel pump (three hoses on it) these do go bad over time and need replaced , also there are fuel filters on all these engines that need to be replaced seasonally they are not cleanable there disposable

try cleaning the air filter, then a touch of starting fluid right into the carburator by taking the air filter off. If it then starts but wont run or stay running, the reservoir below the carb should be removed to clean at and the pinhole in the intake tube above the bowl nut. This is the most common problem with lawnmower start problems, the pinhole can be unplugged with one wire from a wire brush. Be careful with the gas, at least pinch off the gas hose with a vise grips while removing the carb bowl.. Never use a droplight around gasoline. most lawnmowers have no mixture adjustments, so it is a matter of cleaning the carb, tank, gas lines. Some oils in gas mix systems settle and clog after less than one season.

first is there gas in the tank first, then check the fuel pump- take out the fuel hose that lead to the carburetor and crank the engine to see if fuel is coming, if not , check all hose leading to the tank - if ok , check the fuel pump- also check fuel filter too . let me know what is doing

Try a touch of starting fluid right into the carburator by taking the air filter off. If it then starts but wont run or stay running, the reservoir below the carb should be removed to clean at and the pinhole in the vertical intake tube above the bowl nut.

Spark can be tested by sight, remove the plug and use a clip-on ground wire from spark plug body to metal on the engine with the plug wire connected.

you have to performany of these:
1. open the sparkplug & clean it,or you can replace if it is not firing.
2.Clean the carburator,get a compresor or a manual air pump with pin (For ball) and triger directly to the tiny holes inside the carburator.
clean the gas filter becos it already might not flow the gas towards the carburator.

i think it has a diaphram fuel pump in the carburator check to make sure the fuel line is not stopped up and or fuel filter

82 should be mechanical pump,drivers side in front of engine by oil filter,filter is inside fuel line at the carb

if you are getting no fuel to the plug you either have a stuck float, plugged fuel line or filter. does the gas reach the carb bowl? does the mower have a fuel pump? if so the diaphram might be bad.

it could be a plugged fuel filter too check that first before replacing the fuel pump
