I took my pickup ('87 Toyota gasoline carbureted 4-cylinder) for an emissions test today. The guy refused to test it because it smelt so strongly of gasoline. There was gasoline on the ground, and I could smell it too, and he’s been straight with me before, so I drove home instead.
The bottom of the gas tank is dry, as is the filter (which is near the tank, in front of a wheel well) and the lines underneath. The lines in the engine compartment are dry too, as is the outside of the carburetor. I put paper down, haven’t collected any gasoline yet.
There was gas on top of the air cleaner, on the outside, and on the bottom of the inside. I assume this is wrong, but I’ve never checked before. It seems to run okay. I started it for the first time since 2020 October 2. It started up immediately and ran okay.
In front of the passenger’s side rear wheel, a little bit in, near the fuel filter. Of course it could have been from a previous vehicle. This guy is the cheapest in town and also runs a Vietnamese restaurant next door so he can be busy. I’ve been home for a few hours now, put paper under, haven’t found a single drip. I re-built the carburetor 4 years ago, have passed emissions tests twice since.
Next time you find a puddle, smell the liquid. That should tell you quickly what it is. If the puddle is large enough, dump it into a glass of water. If it floats, it’s gas.
I thought about that, but none of my manuals mention it.
Rich enough to backfire? 17 years ago my choke got disconnected; it’d backfire until it warmed up and started with more difficulty. Fortunately the arm had just popped out of the loop on the end of the bimetallic strip, probably on that -17° day I had to drive. It didn’t backfire yesterday and started more like it was too lean until it warmed up.
I was about to take the air cleaner off so I could inspect the float when I noticed that the gasket the PCV valve sits in is loose, no longer holds onto its hole; one of the clamps that holds down the top of the air cleaner butts into it so I often move it a bit. I’ll replace it, of course, as well as the valve. Could that have caused this problem?
