Your answer sounds like it is in your question. If it runs only with the choke on, then there must be too much air sucked in from somewhere. You will have to check all vacuum lines, and possibly start with new gaskets. Also check the float level, could be too high. Good luck.
I believe that the carburetor type fuel/ air ratio delivery system was replaced by Fuel Injection, no carburetor to the best of my knowledge.
Yes it has a carburetor. An engine with fuel injection would be a fuel injected engine.
Because the engine is placed on the carburetor body and the engine is warm. The carburetor should be in the metal to be melted.
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.
It has no carburetor. This engine is Fuel Injected.
No
The engine is fuel injected , so there is no carburetor
The engine is fuel injected so there is no carburetor
The 4.3 Vortec engine never had a carburetor.
Your engine is fuel injected , so there is no carburetor
It does not have a carburetor. This engine is Fuel Injected.
Because the tube (hose) is defective and needs to be replaced. That tube is coming directly from the fuel filter being pumped by the fuel pump to the carburetor. Replace the tube/hose or you WILL have a major engine fire and/or huge KABOOM.
