Makita dcs5200i starting trouble

[TMJ]

Advice welcome..

My old makita is hard to start unless i remove the spark and pour a bit of fuel into the cylinder when cold. Then when warm it is easy to stop and pull start almost instantly. But simple pull starts from cold are impossible unless fuel is added directly. Diaphragm seems to move ok, idles fine, revs up ok. Choke lever moving ok to carb assembly. Is this a blockage somewhere???

I am no expert on this. Any suggestions ???

Few things to check with starting issues: -

 

1) make sure that the choke flap is fully sealing the Carb throat in cold starting position.

 

2) When you start the saw hot with the fast idle on, does the saw rev up to a decent fast idle speed or is it just a little faster than normal idle - if it is low then it could be a cold starting issue.

 

3) worth getting a decent tech to set the L screw correctly as this can cause issues on cold starting if lean.

 

4) if it has a decomp valve then try starting it with out using it

 

5) Make sure the spark plug is gapped correctly, is clean and check the coil to flywheel gap is correct - putting the plug in to the cap, holding it to the cylinder away from the plug hole and pulling the saw over at a less then starting speed should ensure a good spark is produced.

 

Let us know how you get on!

Had a similar problem with a DCS - tried everything - finally tightened up carburettor retaining nuts and hey presto - the carb had come loose and was leaking at the gasket - worth checking - I do it as a first check now to eliminate that potential issue. Good luck
