Good morning, Halyomorpha's

I'm going to the physiotherapist, I also have to buy groceries.
Have things to prepare for tomorrow's wood splitting.
The good news is that there are packages on the way, one of them is vallorbe files, the other is net tobacco from the US.

My understanding from what I’ve seen some great builders post is that the difference won’t be much with the 87. But will be a difference with 198 and good porting. Maybe someone with some real world experience to this will chime in.

The 120 and 144? have the same size venturi ring as the 198 and 199 but the bore is a bit smaller so the venturi effect is lessened, so while they can run right with the 357 carbs they are usually temperamental to tune and pull less fuel on a ported saw.
I put a new 120 on a built 254 and it was killer...
...a 198 on a 346 can flood easily while starting the tuning can be touchy. All depends on what you do with it.

Chitty day bad start to the week. Stuck out of town. My aunt passed away yesterday morning from non hodgkin's lymphoma. Got the call that my uncle left us this morning. That's enough bad news for this week.
Man John that's rough. Sorry to hear this bud

Good information Steve! Thanks for that. I’m gonna try my ported with the 120 and see what gains I see from porting alone first

If you don't dicker up the intake port it will probably run pretty darn good.

I’m excited to try it out!

If you want to go into the play saw realm and enhance the intake port, then the 198/199 will give the fuel you're going to need easily and reliably, especially if hitting a high peak RPM. This is not to say you can't run the 198/199 if you don't, you certainly can.
