I have owned a Dolmar 6800i since new. I bought in around 2000. I bought it to replace a Stihl 042..the problem was it never had the Guts like my 042..does it have problems or did I just have a freak 042? The harder you pushed or pulled on the 042 the more Chips it would throw..anyone that ran my 042 was in awe including Husky lovers. Back to my 6800i.. It has no problems never needed Anything just never had the throaty rev when you bury it to work. It is still like brand new.. I am going to tear it down and look more Closely at muffler ... ANY IDEAS? I will also take a compression Reading? Thanks..
