I am the owner of a new echo 4920 or I will be Monday when it shows up in the mail. The bread and butter for everything I own is muffler mod timing advance and base gasket delete. Obviously this is a clam saw so no gasket delete. However I can find very little information about these and am curious how they respond to timing advance. I've seen the one joe ported but I don't believe he mentioned timing advance in it. I'm all for taking it apart and trying it. BUT I don't have it yet and if they don't like it I wouldn't even bother. I did notice that the pistons are around 50$ so I may try a welded popup later on down the road though. Any other tips or suggested mods would be appreciated.
