MAKITA DPC 7311 PLUG GAP - Makita Saws

SOURCE: Whats the mix for a

50:1 synthetic... one 2.8fl oz bottle per gallon of regular gas

SOURCE: Ive got a Makita concrete

The manual says to mix it 100:1 if using Makita high performance oil or 50:1 using regular Makita 2 stroke oil. I'd go 50:1 with non Makita oil too.

Here is a site to download a pdf manual if you need it.

SOURCE: can I check my makita dpc 7311 coil with a meter

You can check the coil to see if it is open with a multi meter set for Ohms. However, If the insulation of the coil is breaking down your meter may not be sensitive enough to detect this failure. You would need a Z meter to Identify problems and the value of the coil. I believe it would be in you better interest to go to an auto parts store and buy a test plug which is no more than a spark plug with a ground clip on it. You can remove the plug wire on your saw and connect it to the test plug. When you try to start the saw you should visually see a spark from the test plug. If you do then your plug should ignite the fuel. If you do not then you will need to check the plug wire and the input to the coil.
