Thank you for bringing this to our attention. We will have this fixed on our site.
Is there a complete diaphram and gasket set for the carburetor on this tool?
Question: Wrong Gas
I let my friend use my concrete saw, Makita DPC7301. He used clean gas to run the machine and the machine does not start any more. Can you tell me what is the possible problem and solution? Thank you.
Reply: Wrong Gas
You have to open up the whole machine and check the piston. most likely the piston and the piston rings are damaged
Question: Saw Wont Start Out Of No Where
I lent a friend my saw, he said there was concrete debri in the housing where the starter pulley is, causing it not to rotate. He said he removed just the rope portion and cleaned it out and not it wont start. I was wondering is there a certain position the wheel need to be in before placing the started rope assembly back on? if not what are common reason Makita dcp7311 would not start. Replaced plug and cleaned everything already.

Question: Makita DPC7311 No Power
I just bought 2 Makita DPC7311 cut off saws used knowing they had a running problems. One is hard starting seems to be flooding. Once it does start it doesnt have power or take gas as it should. A new carb has been installed within the past 6 months. If anyone knows what are the specs on the ignition coil? resistance and output? It does have spark but Im thinking it maybe too weak.
The other was not starting I removed the cylinder and replaced the rings and its running like a champ..Any suggestions on the first?

It doesn't sound like the ignition coil to me. It might be a problem with the exhaust being plugged up. You might want to remove the muffler and clean it out. Sometimes those mufflers can get a lot of stuff in there which will restrict airflow. If that's not the problem, you should probably check the compression against your other saw. If they're different you may have to replace the cylinder and rings like you did on the other saw.

Hi, just went to Home Depot, they have a couple used ones, they will sell me a non-starting unit for $200... is this a good deal? I checked the compression in the store >120psi, so that looks fine. The ignition seemed weak as well, I pulled the plug out and turned out the lights while pulling starter, did not see any spark. But then I touched the plug with my hand and got a good tingle when starting, so not sure if the coil is the issue. I can certainly try the "clean the muffler" routine, but I get the impression that these units are hard to start and then start to go "bad"... They take a lot of punishment, concrete dust is nasty stuff.
Is $200 too much to pay for this, assuming I might have to put parts in? I have a pretty big job coming up and if I could get it at this price, add a $100 blade I might be in good shape.
