That you brandon?

Yes sir it is. Ive been trying to find a alternative to the hda-87 for the crankcand cylinder that I bought from you, I'm not sure I told you but either someone from ab site or this one offered me a 87 for $100. Iwas thinking about it but first I wanted to see if there were any other options and ran into this thread.
I'm in NC tonight but should be back home in SC by tomorrow night then I can post some pictures of the 212 hopefully by tomorrow night. Thanks again fellas

The 191, 198, or 199 will work with the mods in this thread. Some others may as well .

On the right is the hda-144 on the right is the hda-212. The port for the impulse lines up right. I just had to swap the choke rod and the plate went on fine. The 212 is a bit taller but it doesn't seem like it's gonna interfere with anything?

The big question as to whether it's worth swapping is what's the size of the venturi and throttle plate on the 212.

I'm bumping this thread to thank everyone that contributed over the years.

Here are a couple of relevant links that I think add context and options to the 262XP conversions:

Thread 'Walbro 199 198 191'

Jan 18, 2016

What is the difference in these apparently all fit on 357's or 359's also I've seen 196 and 190, learn me please.

Thread 'Carb options for 357xp (other than Zama)'

Feb 24, 2016

OK, so I have recently been clued in to the little accelerator pump conundrum with the Walbro HDA carbs found on the 357xp and others...

This question pertaining to the 357: Is there any another option besides Zama when it's time to swap out the HDA due to a bad accelerator pump piston that is NLA?

More specifically, is there a Walbor that doesn't run an accelerator pump that can be used?

Anyone ever run a 372 carb on a 357?? Is it even possible?

Sorry if this is a dumb question... This bugs the hell out of me that an otherwise good carb can't be fixed because such a small and easy...

I did the conversion first using a used 199A I sourced from Ebay. The accelerator pump in the 199A ended up being bad. Rather than gambling on another used 199A, I found a new 174 for $60 on Ebay. The 174 isn't an EPA carb and doesn't have the pump. The conversion is easier and the rods spin freer since there isn't drag from the pump. I assume the 190 and 198 feel the same. All of the conversion parts interchange. The 174 has choke plate limit stops like the 199A and 198.

There are three versions without the acc pump, 198 is one of them.
These are much easier to rebuild to 262 than those with the acc pump.
Remember to massage the impulse hole in the carburetor since it does not match the boot gasket perfectly.

This applies to all 3xx carburetors for the 2xx series, the small cubic ones like 242 etc too.

Do you know if anyone ever tried putting the main jet from a 175/191/199 carb into a 174/190/198? All documentation says the EPA carbs have a larger main jet. The main jet is still available.

It's been so many years since I last built 357 carburetors to fit 254/262 carburetors, but if my memory serves me right, the 199/191 is the one with the biggest jets, was surprising to see but it is what it is.
Even I bought alot jets I never swapped and tested.

Mine was pretty close and I didn't end up touching it. I got the saw in wood today and didn't have any fueling issues.

The converted 174 was much easier to tune than the 144 and 120 carbs I have.

For what it's worth here's a pic of an hd 12 I adapted to a ported 262. Was 8-10 years ago and I don't recall many details other than it worked well (and still does).
