There is a screw for the high jet I didn't have a tool to adjust so I cut a line in to make it adjustable with a flathead ,but when I turn it either way my rpms don't go up or down
I have only tuned on the work bench iam new at tunning so iam not to good
At hearing it yet , I been using a tachometer . But it stopped working on me to so I got another one on order. All my other saws are the Mtronics besides my Husqvarna but it's ain't as tricky as the Makita, I will make a vid tomorrow in the light.
So do you remove the secondary sock or prefilter on all new HD saws or just advise new owners accordingly ?Hello, If your Makita EA7900 is not running fully and your photo is correct. Take the top of and take the sock type filter off of the regular filter. I sell the Makita EA7900 but reported to my rep that the extra filter on the heavy duty model was a failure. It should run better with that off.
Well if your restricting that much air your enrichening the air to fuel , potentially leaning out oil to fuel mixture under load . Should also tweak the carb to fatten it up accordingly ?I converted a HD filter model to an EA7900 and sent it to Portland for carburetor calibration. That way the warranty was not effected. As for the sock. If it is one that I stock I will pull the sock off and leave it in the box. If it is one that I am direct shipping I recommend taking the sock off. I think that the sock makes air intake too restrictive and have read complaints about this model with the sock on. I also sent Makita my opinion about the sock and said that I was removing them when I received a HD EA7900 model. I got no negative feedback about this.
Good to see there are some proactive Dealers that have their customers back Cudo 's !I think that you are correct. I sent it to Portland because I did not want to remove the adjustment limiters.
