Most of our old engines will leak without fuel shutoffs. Most came with factory fuel shutoffs (some in inconvenient locations). Most of the time after I go thru the carbs they don't leak or leak very little for a long while....Then it happens,suddenly,usually very inconveniently. Last week I had 3 good running,normally non leakers decide to leak all in the same week. Including a Honda that I hadn't had to shut the fuel off on in two years. One decided it would even leak with the fuel shutoff turned off. Guess I need to buy some new shutoffs.

Yep we've all been there

The engines of the 70's and earlier almost always had a note in the manual to shut off the fuel when not in use. I always shut off my fuel valve when the engine is running then let it idle for a minute or two to get the gas out of the fuel line then turn off the machine which guarantees it will not leak when you store it in the garage.

 

Once the Fuel solenoids came into existence the leaking problems were stopped :D

I'm used to it after 20 plus years of playing with old engines but I found it interesting that 3 all in the same week kicked off a leaking party after no new issues for months....About the fuel shut off relays....I hate them... :poke:

By chance were tanks topped off? That heat wave last week probably expanded the gas pretty much. Happens all the time diesel tanks. Just a thought.

Never happens with the semi's and I checked the injectors to be sure.... :poke:  It might have been an issue but at least one still leaking and it's cooler. Guess I should do something about that instead of watching the puddle get bigger. :flipping_flapjacks:

My bolens HT23 started leaking out the carb a few days ago, I took it apart and rebent the float. It's all working fine now.

I don't  like the fuel solenoid idea that much , the Toro 1 plays up all the time , takes ages to start some times

Once the solenoids quit working, they allow the crankcase to fill full of fuel!
