I should do that with my 66 Datsun roadster. If it sits I have to do a lot
of cranking before it starts.

With a mechanical fuel pump, a small splash of gasoline or
ether in the air cleaner does the same thing with much less
trouble.

Whenever I get ready to go shopping I always open the hood and check the oil and other stuff. Next time I will squirt some starting fluid through the air filter horn and see if that helps. I will buy some small diameter copper tubing and flare one end with my flaring tool for a little funnel I have here. I still want to try out the copper tube 'trick' for putting some gas in the carburetor bowl. Who knows? It just might work OK. It is kind of hard to remove the engine hood cover due to a close fit between the two front seats in my van.
