I'd sure try a pop up piston in mine
I'd guess it would make a good gain up here at 7200feet
I would think that with your wider exaust should make good gains but I'd like to see the gains with just the pop up
Hope it works out for you
With the air injection the filter stays clean a lot longer
I like the new design of the 462
let's just hope it holds up
I'm at 15 tanks thru it and it's still making me smile
Just my opinion but I think it's a big step forward
Sucks to hear that I've learned so much from build threads,
Ive only ported a couple of my own saws and would never have the balls to port someone else's
But I completely understand where your coming from
You might want to reconsider the timeing advance made a big difference in my saw was thinking of getting it ported and after the muffler mod and timing advance I could swear it was ported I'm not a expert but it made a big difference in my standard carb saw
Good luck with the build
I got the STD carb 462 and love it was going to do a muffler mob and advance the timeing before I do I want to make sure the carb limiters can be removed anyone removed this type?
I just ordered one from ALFAO1
