Even completely stock with no MM and spark arrestor still in with carb set a fat 13.8K the 45cc 346 impressed me. Was using 7T 325 carlton K2.
Didnt see any difference in 45cc and the 50cc I ran earlier. Wont be able to tell difference till I have a back to back comparison someday.
Compared to a 5000+??
All saws had stock mufflers and spark screen in.
Just ran the 50cc 45cc 346 set up the same at 13.8k and my like new 5000+ 49cc. After running them with 18" carlton 325 7T same b+c on each.
I noticed the torque difference right off between the 45cc 346 and others. By itself impressive limbing saw. The 50cc 346 has noticeable torque difference then 45cc 346. The 5000+ set at 12.7k felt like the 346 50cc in the cut to me. I would give edge to 346 50cc. 5000+ had the torque difference over the 346 45cc too.
Didnt have the 5105 today to run.
