Is the manifold change a mandatory when swapping carbs or just another choke point?

I have an MS880 on my bench with some go fast bits coming for it including a different fuel metering device.

Does the saw you're working on have a cast aluminum muffler, or a stainless steel muffler?

I hope you have plenty of popcorn as Randy is probably in the hay field by now

Too wet. Heavy dew.....

The intake will need to be changed too Jimmy. Then the jug will need to be ground out to match the intake.

Ok. Glad I checked...get one on the way Monday. This quick carb swap just got more involved.

Guess the grinding will be self explanatory with intake there?

Be sure to get the metal ring for the inside of the intake too.

Will do. My supplier and I talked about it this week....he said he didn't think I needed these bits....

Should need the inner ring to match the boot. Could have him check P/N to see if there are different ones for the 880/088

Any porting news to report yet Randy :)

Yesterday was my test, tune, and package day Todd. And......I pulled a muscle in my back while installing handlebar hose. I'm pretty miserable today so far.....but I'm finishing up some shipping labels and will then get back in the shop. Not sure if I will get much done in all honesty.
