MAKITA DCS5000 WILL NOT START .

[elfinwood saws]

Hi i,m having problems trying to start a Makita DCS5000, it,s got 170 psi compression, it,s got fuel and it has a good spark. Every 25/30 pulls it may cough or a little backfire. Woodruff key is ok on the flywheel.The original flywheel snapped it,s key and i,ve replaced it with a good flywheel, perhaps it backfired and snapped the key, like the timings wrong. I,ve tried a  different coil and it,s still the same, both coils have a good spark, the saw is a non runner that i bought.

I,m thinking the coils may break down under compression or some how the timing is wrong.

missed out some info.

Firstly check that the flywheel and coil are a correct pairing with your crank. Makita and some other manufacturers like to swap the flywheel and coil combinations so worth checking all are all the correct parts otherwise you may have some weird ignition timing.

Other than that, if the spark and compression is good, make sure the needle valve in the carb is holding pressure OK as if it is leaking, the saw will have fuel but just won't work due to it not supplying the correct amount of fuel.

You bought it as a non runner?

Where from (friend or eBay) and have you ever managed to get it running at any point?

 

Itl never start if it's flooding... or not getting any fuel. Check all pipes/lines and look at the carb.

Had exactly the same as you with one of these saws. Went on and on trying everything, sadly i never got to the bottom of it. The only saw that has ever beaten me!

Spud is probably right. Check the flywheel and ignition coil combo is correct.

Best of luck!

Got the makita 5000 running great, i put all the makita 5000 parts onto  dolmar 5105 crankcases and tank, then it started first pull!!!

I never used any parts from the dolmar 5105 that you sent me Andrew, so now i have a Dolkita.

Excellent! Any idea what was wrong with it?
