Question -
I have a V-twin Briggs 16 hp engine on a Cub Cadet that has been sitting idle for several years.
If I dribble gas in the throat of the carb, it will start and run. It appears the carb is passing some gas internally on it's own as it will momentarily run if I shut off the manual add.
This is one of those carbs that has a solenoid fuel cut-off. When I started to work on it, the solenoid was stuck and would not move. I removed it and cleaned some junk off it and it started clicking (moving). Re-installed and the engine still will not run without adding fuel. I pulled the top off the carb and removed what I guess is the main jet. It was clear. I ran the engine with the top off the carb and the inlet needle/seat is passing gas.
It looks like in order to pull the carb off the engine, I will have to pull the engine out of the frame to remove engine shrouding, etc. Before I go to all this trouble, would you have any suggestions? I've worked on a lot of engines but never one of these.
Thanks,
Mike
Answer -
I'd say check the fuel pump, but it must be working since you saw fuel entering the bowl.
I'm guessing you'll have to remove and clean the carburetor. It has been a while since I saw one of those engines, where is the fuel solenoid? In the side of the carburetor?
Let me know.

The solenoid is in the side of the carb. It opens the fuel flow when the key is turned on. Not sure how it is plumbed as I've never had one apart. I believe the pump is okay as it is filling the bowl when it runs. It may be the fuel in the system is so old and stale that it will will not fire. I've seen gas 7 or 8 years old still run an engine. This gas can't be that old, I don't think. No need for a response to this unless you have something to add. I'll get back to you when I get it running. Thanks a lot.

AnswerStale fuel will definitely cause it not to start...I had assumed you replaced the fuel. I've had a lot of fuel, in small quanities, begin to turn stale in less than a month.
Very common, and most profitable repair...just drain fuel and refill. Highly recommend using fuel stabilizer!!
Let me know what you find.
