After servicing the carb,do u retune it?
blacking around the piston is no big deal for a small engine,as long as the piston rings are in order or in other words it still has compression.

check the fuel supply..
the tank should be airtight...
it is a diaphragmed carby...

Makita Model 6093D will not run and it is not the battery

maybe the left right switch/ powerswitch or the motor is on its end , to test this take a dirty piece of a mains cable 120v from one of a damaged device and take cut out about 30 cm is enough split the ends take the great gear-unit away out of the machine that is against the motor or take the motor out. out of the machine of the gears down because when the motor is direct turning on full speed it will come pushed the gear unit may be out from the machine, because of prevent that you will perhaps some lose parts. hold on the 2 points of one site of the cable on the 2 motor connectors and the other end of the cable direct on the battery when it s turning then the switch is damaged , thats the choice .

succes with repair.

I have a Makita BHP454 cordless drill and lately when I pull the trigger it won't do anything. The lights work but it doesn't move. I have to give it a hit to make it work again.. What would b the...

The first thing to check is the battery: is it fully charged, are the contacts in good condidtion and do they make good contact with the contacts on the switch.
Next thing to check is the brushes. Remove the rear cover and check the brushes and springs that hold them down on the armature. If the brushes are worn to where they dont' make good contact or the springs are not holding them down with enough pressure they won't make good contact and sometimes a good hit will make them touch enough to work again. The brush part number is CB-440, if the springs are bad you have to replave the whold brush holder, part number 638614-1.

Makita 18v lith ion battery not charging

Push the battery in and out while pressing the trigger on the the drill to see if there is a loose connection here.
Check the battery terminals inside the drill and the battery terminals .These sometimes become tarnished and don't make contact. Clean with very fine sandpaper or wire wool. Apply light pressure as otherwise you may remove the chrome or nickel plating on the contacts.

I have a Makita #6347d, when I have been using the drill I had some smoke from the battery connection to the drill and the housing of the drill had some smell of smoke. Whats up? Thanks, Bill

Check what gear you in, the Makita will smoke if you exert to much torque, consider buying a decent impact driver? If its not under much pressure then it may be a fault with the drill. I have owned one and it was reliable but sometimes under-powered for an 18volt compared with others on the market.
Hope this helps

How to dismantle a makita HP electrical hammer drill, want to replace the brushes

Check out the split drawing on this page.
If your makita does not have any outside accessible brush caps, you need to dismantle it.
lay it on the side, where the side with the screws securing the to halves together is facing up.
Remove all screws (some may be hidden under labels etc.) Gently pry the halves apart, locate the brushes disconnect their leads if any, and remove. Install new brushes and make sure the move freely, and that they are springloaded when in place. Gently rotate the rotor to ensure everything is ok . Reassemble and test drill. If the brushes leaves long streaks of noticeably large sparks, something has gone wrong or the rotor was damaged in the first place, causing excessive wear.

Makita dpc6410 not starting

i know you said the compression is good, but the number one problem with these saws is the cylinder dusting out (scaring).

before you tear off the cylinder, just double check a few things.

your fuel mixture is good
your decompression valve (depending on year bought) is not seized in the open position
you exhaust isnt blocked
check the plug (my 14" makita uses plug BPMR7A, sometimes i find a BPM7A in it)

if everything looks good, i'm sorry to say you're going to have to remove the cylinder.

remove the filter cover and starter coil
remove the shroud holding the paper filter being held on by 4 screws
remove the plug and unscrew the ground wire from the cylinder shroud and push them aside
remove the 3 remaining screws from the cylinder shroud and remove (it wont come off easily)

now you should be looking at the carb assembly hooked into the cylinder by 2 connections. loosen the hose clamp as much as you can, and be EXTRA careful removing the small hose connection. (they love to rip)

you can either remove the carb housing or leave it in. if you leave it in, you're just going to have to move the cylinder around it to get it free. if you take it out, you just have to make sure you plug the fuel supply and prevent debris from getting into the tank from the top.

i usually take the cylinder and exhaust off as one piece because the 2 exhaust screws love to get seized up in the older saws and it's just more of a hassle than it's worth. remove the 4 screws holding the cylinder down and you should be able to pull the cylinder straight up.

look for discoloration around the exhaust port and vertical lines, also check the piston to make sure the ring isnt fused to it, or broken.

i'll keep my eye on this, so if you have more questions i'll try to keep up.
