Gas Fumes

[mcutlass1969 0]

Gassy smell. About a week ago after i got done mowing with my 520-H i parked it in the garage. over the next few days the garage started filling up with gas fumes. Typically if i left gas in an ole coffee cans it would have the same effect. So now trying to trouble shoot why the tractor is now doing this. I looked over the tractor and see no leaks or anything. I am now starting to wonder if it isn't the gas cap. Any thoughts?

 You may have a small leak or spray elsewhere on the tractor that your not seeing. This has happened to me before. Around the carb, fuel pump, under the bowl or fuel filter. It doesn't take much but if it get around grease or grass deposits, it can small a long time. Also check around your fuel tank. If the gasket is bad on the cap, it will do the same thing from sloshing around.

My wife can smell that from a block away and my shop butts up against

the house I really got to stay on top of anything like this.

Had a leak with a chainsaw a while back and blamed it on a tractor

Drove me crazy for a while.

A woman brought a car into my brother's garage last week because it had a strong smell of gasoline inside it and she couldn't figure out why.  While driving it into the bay, he heard some sloshing in the back, opened the trunk to find a chainsaw and 3 cans of gas in the trunk.  Hmmmmmm, wonder where that gas smell was coming from?

My wife is also one that has a sensitivity to the gas smell.  As a rule, I have to give any "new" tractors a good wash before I bring them into the garage so that she doesn't complain too much.  Fortunately, she likes the smell of fresh paint, so she doesn't complain about that.  

 

I had a tractor once that had a leak in an old, cracked fuel line near the carb.  It wasn't enough of a leak to drip, but would weep and stink up the garage.  Put on a new fuel line and tightened the clamps good, and it cured the smell.

   I would start by pressure washing everything on the  . It is hard to find a seeping leak under dust and dirt. It could be just a few drops of gas spilled while filling the tank but you won't know until you start claen.

 

Good luck and let us know what you find.

 I have a leaky fuel pump on my 875, so I have to shut the fuel tank valve everytime I am done mowing. The fuel in the line to the pump still drips out and the pole barn is really "gassy" smelling.

Really.....?  Pressure wash a 520H...?   I'd rather think there are some electronic components or circuits on the engine periphery that will take objection to being hyper-blasted.  Even if not directly assaulted, the overspray and mist will also saturate virtually every wire connection.  Certainly there should be a less severe attack mode to rid the tractor / engine of the gas odor.  This is, of course, IMHO.

I am fighting the same problem right now. Got a C145 that has been stinking up the place and can not figure where it's coming from. New gas lines, clamps checked tank, just can't find it. It's not exceeding strong just annoying. I was checking to see if the float was sticking while it was shut down letting the bowl to overfill. Did not see any evidence of it.

 

Wives are not sensitive to gas smell as much as we are loosing are sense of smell by being around it all the time. (Sounds like a good excuse to me)

 

Also I pressure wash my 520, I just don't get around the electrical. Yes it does get some mist on it from time to time but usually not. Also I am very persnickety about checking wire ends and terminal for the greenies. You get that whether you wash them or not. We all know how well 520's and the greenies get along.
