Almost always the fuel pump. Slight chance of the injector, but normally the fuel pump.
On my 49cc scooter engine the carburetor is found on the engine. The engine is broken down into 3 parts, the part to the left (looking at it) where the air filter is is right next to the carburetor.
If the tracker is a "standard shift" not automatic transmission. You could pop start the engine by putting the car in 1st gear, with the clutch pedal down and the ignition on. Roll the car and once car is rolling release clutch pedal. Vehicle should start, hope this is what you ment by "manually".
In late 1987 chevy went to fuel injection on ALL there engines. From 1987 down will have a carburetor.
I Would say the choke on your one barrel carburetor is sticking Start the engine. Let the engine reach operating temperature.Remove your Air cleaner to your Carburetor while the engine is running.Look down the throat of the carburetor and you will see a round flap A.K.A the butterfly.This flap should be completely open when the engine is at operating temperature open so that the air can pass through the throat of the carburetor freely. If you don't understand how a choke works go to howstuffworks and ask how a carburetor choke works and it will all make since.
Usually when your pressing down the gas pedal to start, at this point your carburetor has already flooded your engine with excessive gasoline that it does not need, so when you press the gas pedal all the way down to open the the carburetor ports all the way it allows the engine to get rid of the excess gas and the fumes until the right mixture or gas and air are obtained. The smell of gas is caused either by a leaky gasket within the carburetor or possibly a incorrect adjustment of the air/ fuel adjustment screws. I would definitely take the vehicle in to have it checked out because under its present condition, your engine could backfire and cause a engine fire very easily.
the engine timing could be off. Or, the fuel mix is wring. Or, the choke is sticking and the carburetor jets are out of adjustment.
To troubleshoot and clean the carburetor on your Honda pressure washer, follow these steps: Turn off the pressure washer and let it cool down. Locate the carburetor, usually found near the engine. Remove the air filter and inspect it for dirt or damage. Use a carburetor cleaner to spray and clean the carburetor thoroughly. Check for any clogs or debris in the carburetor jets and clean them out. Reassemble the carburetor and air filter. Start the pressure washer and test its performance. Cleaning the carburetor can help improve the performance of your Honda pressure washer by ensuring proper fuel and air mixture for efficient operation.
If it is a fuel injected engine then you can not adjust the idle, it is computer controled. There is no idle adjustment. If it is a carburetor then there is a small screew over by the throttle cable, down towards the bottom of the carburetor.
It is bleeding down---- Leaking fuel out of the fuel bowl and flooding the engine. In other words fowling the spark plugs out. When a engine is cold it needs more fuel to start. But when a engine is hot it needs less fuel to start. You need to make sure the choke plate is opening all the way up when engine is hot and it should stay open until engine cools off. If it is closed when engine is hot that will also flood the engine and it will not start. If choke is working then REBUILD carburetor.
Carburetor adjustment or if unattainable rebuild the carb. about $20 and 1/2 hr Before you start messing with the carburetor, check the air and fuel filters.
Check battery first for proper voltage. If battery is good and your engine will turn over, check for ignition spark through ignition cables to spark plugs. If you have spark, check for proper fuel pressure. If battery is good but engine will not crank, suspect either the starter, solenoid, or ignition switch. If your problem is not caused by one of these, consult a mechanic. Look to see if the carburetor is working correct, if so try putting some gas down the carburetor, NOT A LOT or you will make the biggest back fire u have ever seen coming out of the carburetor, if you put to much gas in the carburetor step back and try and start it. Do this after u have tryed the other suggestions from the first post..
Need to know what year, engine size and if it has a carburetor or throttle body injection (TBI).
