I got a Stihl 044 I have been using for a couple years. Power is starting to go, and it is bogging down a little. I did a compression test on it and it is holding 125 psi with three to four pulls. I have not pulled the muffler to see if there was any piston scaring. I am a pretty good auto mechanic, but have no experience with these two cycle engines. My question is how hard is it to rebuild this Stihl 044 with a new piston possibly a totally new jug. I would like to hot rod it, and put the largest piston jug assembly and a modified muffler in it to get as much power as possible. Not sure how much the Stihl dealer would charge, but I am sure it is not cheap. I plan on getting my parts off ebay if I can. Any advice or comments are greatly appreciated
