I just got an 088 and was thinking of MM it. Will it make much difference like it would on a new 880? I know the hole in muffler does'nt look very big at all.
 
What parts are you needing?

Has anyone done this to their 088 or know if it will make a difference?:confused: I am wanting to do this in a bad way if it does.
 
Yes it will, but be very careful in tuning the carb. There's a good chance you have a rev limiting igntion which make it quite difficult to figure out the correct tune. Best way - timed cuts for best time, then make it a tad richer.
 
How can you tell which coil you have and how large should I make the opening? What RPM should I tune to? I don't even know the factory RPM. Sorry for running on with so many questions but thats kind of why we are all here is'nt it. And to shoot the shoot of course.:dunno:
 
So Lakeside, which is the best. The 088 or MS880. I remember you writing that the 880 has the better bearing set up with the insert. So which is the best carb and best coil and best saw to make up if you have all the parts to do so. Thanks Dave.
 
Only the first year or so of the 088 had the crappy crankcase with no insert. Beyond that, the 088 and 880 are pretty much idential.

There are three different coils. One is not limited. Apart from tuning ease, it make no difference unless you are "excessively" porting the saw and have in-wood cuts speeds over 11-12k (not a work saw..).

88/880 carbs are all the same. Some guys like to put the early 084 HT carb on, but again, they are racing...

Factory "max" RPM is around 11,750-> 12k.. but it's not a very useful number. That would be with a decent size bar/chain and you will likely hit the ignition limiter around 12k anyhow. Don't just tune to an rpm (tach) number; tune to best cut times in big wood (saw pulling say 9k) then tune a little richer for safety.

Easiest way to tell your if your coil is limiting is to pull the carb limiter caps and wind it up - if it goes to 13k, it's not limited. Be quick though, and only do that on a warmed up saw... and set the carb back after...

Hole size... I'm no expert here... Try 3/4 inch... or any size you like to experiment with. It will be LOUD. Dead easy on an 088 - just make a plate with the appropriate hole and screw it into the muffler

How would I go about finding out what year it actually is?
