I have a Tecumseh OHV130 206810C. It sat idle for 2 years and was gummed up. Cleaned everything up but can only get it to run by spraying gas into the air intake. Could there be a fuel pump problem and if so where is it?
You follow the hose from the bottom of you fuel tank right to the fuel pump. If you don\'t have a pump, that same hose will go to your carburetor. Either way disconnect the hose from the carburetor. Put a can under hose and turn over engine. If gas flows your pump is OK. Next remove bowl off bottom of carburetor, ( with can under bowl), I believe you will find crap & water in the fuel bowl. I would drain all fuel from tank, hoses, and pump. Clean fuel bowl , you may need new bowl gasket, put in fresh fuel, try to start. Water in the fuel is a very common problem when you hear NO START. Caution when dealing with fuel, remember SAFETY, SAFETY, SAFETY, and did I forget to mention SAFETY. GOOD LUCK FRIEND.

Dont replace just one O ring on the injectors. You need to replace all when you replace them. It sounds like you still have O ring leaks.

Fuel pump circuit (low voltage)
Try replacing the fuel pump relay or testing it if you have the manual.
SOURCE: car won't start without adding gas to air intake then won't idle
Check the fuel filter, you may have clogged it when you filled the tank.

The fuel in the fuel tank also cools the pump during operation. The pump could have heated up internally, causing it to fail. I would recommend checking the fuel pressure with a gauge and be sure the fuel system is pressurized and not low. A fuel pump can still run and be heard, but at the same time, it also may not provide enough critical pressure to the fuel rail and injectors.
