The only true problem with primer bulbs is the snap-in Walbro ones have a tendency to break the small tabs keeping them in place and replacements are ridiculously expensive.
As an aside priming and not priming a cold MS193T seems to make zero difference.

Not all that expensive really. A little more than the aftermarket ones maybe..

US prices, multiply that threefold to have the European price. I have bought a couple two weeks ago plus a batch of Walbro fuel filters so the horror is still hetched in my brain.
They are not just losing to the Chinese here: they are rolling out a nice big red carpet to them.

Hopefully you all will not import their virus as well!US prices, multiply that threefold to have the European price. I have bought a couple two weeks ago plus a batch of Walbro fuel filters so the horror is still hetched in my brain.

Luckily we are doing something about the Chinese problem here, hopefully we can get the job done before they get rid of our president.

Whenever you try to start a high compression engine with a long fuel line and no compression release valve, you wish you had one of these. Would save the time and trouble of taking off an air filter so you can squirt some fuel direct into the carb.

I didn't like primer builds either, until I got a 346 in 2011 with one, then a 562 in 2012. No issues at all. Two to three pulls when cold & been sitting for weeks.
I also did not trust primer bulb type saws, especially if I needed to use the saw on a cold day way back in the boonies.
Could not trust the bulb to operate without cracking, deforming, and would have to prime with a gentle touch, especially if the bulb was over 2 years old and price of some of the replacement bulbs were not reasonable.
I knuckled down and found a supply of primer bulbs at a reasonable prices on-line now days so I just replace them when one gets weak. (easier to get parts on-line now days instead of mail ordering) I live in rural area and access to parts not readily available locally.
If I did not do my own repairs I would stay away from primer bulb saws. Cannot even imagine what a saw shop would charge to replace a primer bulb and if saw needed new primer bulb it would most likely need new fuel lines also.

These are not primer bulbs.
I also have a Sthil trimer with a purge bulb, it's at least 10 years old with never any issues.

Me also. Have a 10+ year old $69 Craftsman string trimmer with a purge bulb, never replaced it or has given me problems. Now it probably will not start this spring, but will take my chances.
Purge bulbs work great until they crack, in cold climates they require replacing more often, some makers machines will only last a couple years while others last for decades, materials used must be different.
i watch for assorted packages of primer bulbs in the clearance racks or garage sales, there's only a few common sizes of them. I've often wondered why we never needed them for so many decades and now we do. I have one saw with a bulb the rest are just a choke and somehow manage to start, and only one fuel line to worry about!

People are getting weaker and manufactures need to make them easier to start.
