I have no primer and it works fine. Get the engine turning over, then pump the throttle a couple of times and it lights off. The only disadvantage is there is not much way to prime the engine if you have to hand prop it. Different strokes for different folks. Do what ever works for you.

Couple reasons, when it's cold here even though my engine is plugged in and warm I need to leave the primer out about 3/8" to act as a choke for the first 20 or 30 seconds to keep it running.
Reason 2 is if your hose from your gascolator get blocked or your carb has a flow restriction you can pump yourself home or at least to a more friendlier area.
Reason 3 is if you foolishly run out of gas or enough fuel head pressure while over woods you might but be able to pump another mile or two and make it to an airport. Don't ask why I know this

Just make dang sure that engine is turning over before you use the accelerator pump. I’ve seen one airplane burned to the ground by someone trying to start with the accelerator pump.
i MUCH prefer a primer system and USE IT to start. If you have fuel injection, how you going to prime that engine to prop it?
As George said, put the fuel in the cylinder, not the lower induction. One little back fire can ruin your day. Doesn’t happen often, but it’s really bad when it does.

Yeah, that's why the baby Continental primer system is kind of a joke. As Fancypants said, there's no option for cylinder prime, to my knowledge. So the primer puts fuel in a difficult to atomize and dangerous spot.
Out of curiosity, what is you sequence to start your cub?I don't have a primer in my Cub and no starter. Has worked fine for about 25 years once I got the sequence down.

I also have no starter or primer. Three shots of throttle and the third blade it usually starts. If it’s very cold, it might take a min.....Pierce, txpacer and BTV witnessed my cold weather workout routine.
I would also like to inquire as to where Zaylor operates from?
I flew Conn. winters allot.
When I had my C-150 I recall pre heating it a time or two. I generally just fired it up cold.
I did however richen and lean the idle mixture seasonally.
I will double check, but I don't think I have any pipe plugs in my cylinders. That's what I am looking for right? I would much prefer cylinder prime. They are shown in the IPC though, hmm.
The Clipper we were flying skis with today had a carb.problem last time out and quit running, he pumped it back to a safe landing

What engine? The staock carb on the O-235 on the Clipper didn't have an accelerator pump.
Tried your idle cutoff start procedure today. Works just as you say. Thanks againCold, I give it a couple of pumps on the throttle and pull it through about a dozen blades, one shot of throttle and it'll start on the third blade. Warm, I give it one shot of throttle and it'll start on the third blade. I always start the engine with the mixture at idle cutoff. It'll run for a few seconds which is long enough to make sure everything is OK. When I'm sure my head is not planted where it shouldn't be, the mixture goes in.
In my opinion, the propeller is there to pull the airplane forward and to kill you if you're not careful.

I bet if you give it 2 pumps of the throttle and go Hot it will start on the third blade
