Priming the carb

I don't have a priming electric pump on the 38. I'm weary of the load on the starting system with the excessive starter usage after the car sits for an extended time. I bought a squeeze bottle to use to fill the float bowl of the W1 but I'm not sure of the best way to do so. Looking at the diagram in the link below, it appears the "slip nozzle" connects directly to the float bowl. Would that be the best route for filling the bowl without having to remove the air filter and bowl cover each time? My plan is to remove the air filter lid, open the throttle to lift the metering rod out of the way, then use the squeeze bottle of gas to push gas into the float bowl through the slip nozzle. My intent is to do this without having to pull the air filter off of the car. It will work? It won't work? Ideas? Suggestions?

Hi Tiny

That may work, but it may also be a bit tedious.

It's certainly worth trying.

 

We have a few vehicles on the farm that take some time to fill the carburetor after sitting for some time as well.

What I now do is clean the top of the air cleaner and back the wing nut off several turns.

Then, leaving the top of the air cleaner in place, I pour/squirt a good shot of gasoline down past the stud the wing nut was on.

The shape of the top of the air cleaner works to funnel all of the gas in.

Then I start the engine (and it starts immediately) , and the several seconds that it runs is usually enough to fill or nearly fill the carburetor so that even if the engine doesn't continue to run, a second squirt does the job.

Then of course the wing nut is retightened.

 

Leaving the top of the air cleaner in place is my "safety measure" and has ensured that I've never had a back fire.

And it never takes more than a few seconds of cranking time.

If everything else is in order.  🙂
