    hey guys I have been bragging about shindaiwa 8510 backpack blower I love it. It has served me great for the past 10 months I have had it. But for the past couple times It has been getting harder to start when cold. Today it took seven pulls and it cranked up and ran great. it used to be two every time. After it warms up it takes like half a pull and it starts. do yall have any I dea why it would do this? thanks.

    Sounds like its not getting gas, do they have a primer on the carb? Maybe change the plug also.

    Is the choke operating correctly? Air filter clean? Post your starting procedure step by step...

    could you be using 87 oct instead of 89 oct fuel. That will make a differance.

    You may want to up the mix to 89 or 93 octane. Also, do you have the throttle set at idle, half or full while starting.

    I always leave it at full throttle. Prime 2-3 times. Choke on, 1-3 pulls (if it don't pop start sooner), take the choke off. Full throttle still till it fires. Thats usually the first start of the day. After that, usually starts with one or two pulls from half throttle.

    Hi all; JimMac from Boston here. There is a small screen which will get clogged after a lot of use. Clean this screen for better performance. this screen is located either (both?) behind the muffler and/or beind the engine crankcase ventilator tube. 2 cycle engines can get clogged this way. Also, make surer the air filter is clean and there is no debris (leaves) blocking the air inlet main fan. --and remember-- he who dies with the most tools wins!
