How to adjust a carburetor on Makita ek7301 it has covers over the adjustment screws.. and it will not pop or start?

SOURCE: Husqvarna Chain Saw Rope Pulls Very Hard, what is the cause?????????

Has it always done this or has it developed?
Some saws have a decompression button to make it easier to pull over.

SOURCE: Stihl ms 250 chain saw won't start, doesn't seem to catch spark.

SOURCE: My Poulan Pro 200 model #200pbv200le will not

Check your compression...if it reads anything less than 100psi you need to tear it down and replace the piston ring. Looking for the spark is unreliable, get an in-line spark checker and check for spark. Loss of compression due to a stuck piston ring is very common in the pbv200 series.

SOURCE: NO SPARK, HAVE NEW PLUG BUT IT CONTINUES TO FLOOD.

If raw fuel comes out of the muffler then you have an extreme flooding condition. There are no Model Numbers to tell me which type of saw we are working on but this works most of the time.

Try this: Remove the spark plug and BE CERTAIN the stop-switch is in the OFF position. Take the saw outside and bring a fire extinguisher with you! Hold the saw by the rear handle and let the muffler hang down to the lowest point possible. SLOWLY begin to pull the starter rope and observe the fuel being pumped out of the muffler. Gradually increase the speed of the rope pull and get as much fuel out as possible. When satisfied that it's dry, it isnt. Use compressed air to LIGHTLY blow into the spark plug hole and continue to pull the rope. (Might need 50 or more pulls!) Blow the spark plug dry and reinstall it.
Turn the switch ON, leave the choke OFF, and hold the trigger wide open. Start the saw and allow it to run at full throttle until it clears out all unburnt fuel and has good throttle response. If you need further assistance reply to this post with the make and model of the saw and I will be happy to help.

Hope this is helpful,

Hi and welcome to FixYa, I am Kelly
Remove the muffler and clean out the exhaust port and screen. You will have to disassemble the muffler and clean off or replace the screen item 8 of this link:

Before taking the muffler apart... unhook the spark plug and just pull it though with the muffler removed. If it pulls normally you know you have found the problem.

If it still pulls hard...check the exhaust port of the cylinder head for 2 tiny holes (not screw holes) Some have them some don't depending upon the year of the saw. If you do find 2 small holes that appear clogged with carbon... do your best to clean them out.

Thanks for choosing FixYa,
