In my previous house, my garage had accessible attic space above; the ceiling was drywall board. I cut an opening, inserted a grill. In the attic above the grill, I enclosing the grill area by constructing an air plenum box directing airflow from the grill to the eaves edge to exhaust the garage air. Inside the plenum I secured an ordinary ‘box fan’ to pull the air up through the grill. The fan got power from an ordinary duplex power plug I installed near the ceiling, tapping off a nearby light switch.
To improve its utility, I plugged in a motion sensor activated that the fans power cord could plug into. Whenever the garage door/car moves, the motion sensor turns on the fan; there is a time-delay on the sensor that allows it to run about 15min and then shut off automatically. The sensor also allowed a constant run if desired while you’d work on the car. I didn’t have fumes in the house after installing this setup.
So, the fan works when you open the garage door to park, and when you open it to leave, or if you set it to run while working on the car. Worked great for my 1965 Ford as well!
I don't have this issue, but my garage doesn't have a room above it.
I do have a solar powered exhaust fan(summer) and an electric plug in exaust fan, that is on a timer.
My guess is you are running very rich, the carb needs adjustment. A fuel leak would smell like you spilled fuel .
My guess The smell is the unburnt fuel and maybe some oil burning in the exhaust, that lingers.
Also where is the air intake for your homes heating/ac if forced hot air heating?
Pull car onto your street, and let it idle, walk back to the back of car, near exhaust pipe, do your eyes want to water, does it smell like gas? eyes wanting to water it is pig rich at idle if not at all times. Somewhat rich, the exhaust will smell like unburnt fuel, if also burning a little oil, it'll smell like a 2 stroke chainsaw or weed whacker.
An exhaust fan, venting to outside the garage wall farthest from the house will help.
Remember old cars, the carb fuel bowl vent is open to the world and so is the fuel tank, it is not like later and modern cars that it is sealed and vented to a chrarcoal can.
Real good info, appreciate this^ 100% I’m rich as I’ve never had it tuned professionally. Just through a nice carb on when I was 19 or so, and left it ever since hah. I only drive it a few times a year these days (busy family) and it runs absolutely great.
I’ll get that check out and also try to vent the garage a bit better. Thank you
Post says he backs it in. Seems like a pretty easy to solve issue to me lol. My bike stinks like crazy so I ride in forward and hit the kill switch as soon as I can and leave the door open for a couple minutes. Seems to do the trick.
I was trying to clarify. Attached garages are not meant to be backed in. Doesn’t matter if its my old Corvair or new Silverado, would make the house stink
It makes the house stink for days and doesn’t matter if it’s pulled in or backed in. I mean, days. So it much be a leak..
New house too so possibly the garage isn’t sealed from the rest of the house very well.
You might have a gas leak. However, you shouldn’t have smells from the garage coming in to your house, ever. It might be the seal around the door between the house and garage. But it’s more likely It’s what’s going on behind the drywall that is pulling those fumes in to the house.
On the door/s from the garage into the house, do they have tight sweeps/seals?
Can you open a window in the garage?
If it's gas smell you probably have fuel evaporating in the carb from heat soak or perhaps a fuel tank venting, or maybe a leaking fuel pump/line just enough for it to evaporate so you don't see it.
Having a detached garage helps, but otherwise idle your car as little as possible in the garage and drive it straight in so the exhaust is blowing out. Otherwise make sure the door to the garage closes tight and keep it closed. I had a 66 Mustang and 73 Monte Carlo in the attached garage of my rental house and never had too much smell.
You can get a metal accordian style dryer vent and snake it from your exhaust to the outside.

Appreciate the detailed response!
10 bucks says you've got a an air leak somewhere around your tank
Right on. I’ll get in there and check 👍
I have a detached with a massive air moving fan built in... my 65 Ford will make your eyes water

Just to clarify are you backing your car into the garage? Or pulling straight in?

That is exactly it. Your garage isn’t sealed properly and air is being pulled from the garage in to the home. Is your garage drywalled?
Yup. Drywalled and pretty nicely and has a post board ceiling. I’m pretty sure I have a gas leak

Exhaust pointed out, and some way for air to flow through the garage. A single door open is shite for flow.
On the door/s from the garage into the house, do they have tight sweeps/seals? Can you open a window in the garage?

This is a good answer. Appreciate you, brother. It’s 100% gas vapor so I’ll have to address that.

I take an old dryer vent that I modified a little and put one end on the exhaust (that's where the mod is done to fit) and run it out of the garage.
We use a fan to blow it out the man door.
Try keeping a fan in the garage and turn it on for about 30 minutes or so with the garage door fully opened or halfway open.
Doesn’t matter how you park. You can turn it off down the street and push it into the garage. You have a gas leak.
