I posted this previously, but I made the mistake of having too many topics in one post, so here goes...
I bought a used logger saw with about 10 holes punched into the muffler, I realize that the H jet will need enriched over stock, but am I running any risks of damaging the saw because of too many holes?
What would happen if you took the muffler off? (other than heat and noise...) - not that I plan to, I am just trying to understand how these engines work...
In the car world running open exhaust seems an area for debate. some say no problem, others say that engines need some back pressure and the cold air going in on shutdown leads to cracked valves...
