Spark arrestor on a new Generac
Hi, have a new Generac (17.5 Kw) with less than 20 hours. The spark arrestor fell off. It's just a connical screen with a collar. Seems to have had some threads on the collar to hold it to the muffler pipe. The threads are now gone, and probably need a new one.
Question is, on a new 4 stroke gas engine, can I run for 20-30 hours without a spark arrestor? (Seems they are more important for engines with carbon buildup.)
