Some of you liked how the MS290 ran when I posted the video of it in the hickory log. Today I did a video of the 290 against a stock 034 and the Terry Landrum Ported 660. Here are thee specs. 290 was just rebuilt and slightly modified and is wearing a brand new Stihl RS chain fresh out of the box. This saw is running 87 octane pump gas mixed 40:1 034 is bone stock and very clean. 185 PSI of compression and wears a brand new 18" Stihl RS chain fresh out of the box. This saw is running VP Race Fuel SEF 91 octane ethanol free at 40:1 660 was ported by Terry Landrum and is running very fat on the high end as it is tuned to run a 32" bar. It is wearing a 20" bar with used, never sharpened Stihl RS chain. This saw is running VP Race Fuel 91 octane ethanol free at 32:1 (milling saw). Here is a picture of the 3 saws. Here is the original video of the 290 in Hickory. Here is the video I did today.
