The DPC7311 is a two-stroke demolition saw, there should be no standing fluids, oil or otherwise in the crank case to leak out. The reason it uses a 50-to-1 gas-to-oil mix is so the oil in the gas can settle on the moving parts and lubricate them.
If you do have anything leaking anywhere out of your crankcase you most likely have problems with your carburator in that too much fuel is getting into and filling up the crankcase.
You should also look to make sure your leak isn't coming from a crack in the fuel tank or from the carburator or fuel line and running down to look like it's coming from the crankcase.

Makita dpc7311 wont start after heating up. first start pretty easy after warming up will not idle.

The deposits on the spark plug are not a real big concern. The issue may be related to hoses that are cracked due to age or the jets on the carb may need to be reset. There is a high and low screw to do this. Also make sure that the woodruff key that holds the flywheel to the crank is not loose.

My makita dpc7311 has no spark, replaced plug, coil, flywheel, what else can it be

Check the ground wire from the coil all the way to and including the contact point at the choke switch. I've encountered a couple where insulation was worn off or the wire was pinched and making contact with the head, carb or other metal part and grounding out the coil.

Makita concrete saw, no spark, new ignition coil.

Check clearance between the coil and magnet, too far away and magnetic field won't generate.

Is the gas fresh? Is the plug wet with fuel after you try and start it? Have you done a compression test on the engine?

Were do you pot the oil in **** cuter

Hello. I would be happy to answer your question. The DPC7311 uses a glorifieds chainsaw engin and takes mixed fuel - I believe the manual says to mix the fuel:gas at 100:1, but that is with a specified Makita high performance oil. Most people mix it 50:1 and use normal two-stroke oil (actually it covers that in the manual also, I just found the info on page 12). The oil itself comes with the measuring cup (or marks on the side of a transparrent window), and has specific measurements listed on the container.

For your reference, I've included the links to the manual and the parts breakdown, both on this page. Hope this answer is what you need. Thanks.

Ive got a Makita concrete saw DPC 7311,it says a mix of 100:1 but thats alot ?

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.

check compression with a gauge bet its under 100. if so check piston and rings, Most of the time you can just hone cylinder and replace rings.
