    I bought 2 brand new Shindaiwa T270's. One is good, but the other is Waaaaaay stronger. Any little things to check for? I pulled the plug to make sure it wasnt fouled, and it wasnt. Not sure if theres anything easy I can look for before I take it to the shop. I dont want to tear into it cause its brand new

    Try checking the spark arrester screen in the muffler. They clog up very quickly and can cause a huge loss in power.

    Compare the two side by side, look at where the throttle connects to the carb to see if you have the same travel at wide open throttle (WOT) It might just be an adjustment, also check that the grip in the tube is not twisted and that the trigger assembly is at the right place.

    I had checked that. It seems that one doesnt move nearly as much as the other. How do I adjust that?

    It's been a while since I've worked on a shiny, but if it's a walbro carb, there should be an adjustment nut and sleeve that the throttle cable goes though

    You will need a 8 mm and 10 mm wrench.

    Take the 10 mm wrench and turn the nut out a 1/4 turn. Hold the nut with the wrench and now back off the sleeve with the 8 mm wrench. The sleeve goes through the nut and into the support on the carb, watch how much you back out the sleeve from the support, you don't want to take it completely off.

    Once you have the sleeve backed out, you use the nut to lock the sleeve in place by tightening the nut against the support. Test the throttle play as you are doing this, or do like I do and just run the sleeve out as far as it will go :) Start the trimmer up and see if you have improved the power.

    It is so much easier to do it then to explain it :laugh:
