Chainsaw Repair

I tested a pipe in a 066 cover that went across inside the front that the internet guy selling makes. The stock OEM DP cover for 066 flowed better.

I also tested a pipe in same config for a 084 cover and my simple caveman muffler mod with 288 deflector on cover out flowed piped one too. 

My conclusion was my ported 066 and ported 084 ran better and had quicker cut times were made with oem or added deflector to cover over the pipes across the front cover.

To me the Ohio internet guy selling these piped covers for big bucks is. 

084 simple caveman DP muffler cover mod.



084 muffler with pipe.




This is 044 046 cover. Sent me the wrong one.  Digging for 066 piped cover which was better then stock, but not better then OEM DP or simple no cost muffler modding.
