I have a 1995 Townace DX flatbed pickup with the 2Y gas engine. It runs very well, but after a drive there is a strong gas smell that accumulates in the cab.
If I air out the cab and let the truck continue sitting for a couple days, the fuel smell does not come back - so it seems to be related to when the engine is running.
I don't notice the smell while driving or idling.
Sometimes, after driving and then letting it sit for a little bit, it will take longer to start. Perhaps the carb is flooded?

Any tips on how to troubleshoot this are greatly appreciated. I am tracking down a 2Y repair manual right now...
