Remove limiter caps for muffler mod?

[zryder25]

if I mod the muffler on my husqvarna 340, will i have to remove the limiter cap on the high jet, or will it richen up enough without removing the cap? Sorry if this has been asked a lot before, but i couldn't find this doing a search.

You won't know until you try.

Connecting the tach will tell you the answer. It's getting much tougher to properly tune a saw without a tach these days.

if it moves more air now... it will need more fuel.
the fuel requirements may well be beyond what is an allowable ajustment by the limiters. buy a tach, find your rpm specs, make more power, and go cut wood!
