Chainsaw Repair

Hi!

Recently I was given a 2nd hand Makita DCS340 as a gift, It's pretty good for what I need (general garden use and a bit of firewood making) but, after running for a while, once it's properly warmed up, it becomes impossible to start.

I'm pretty sure I'm not flooding it, it just needs time to cool down, then starts happily, I've somewhat worked around this by leaving it in streams between uses to cool it down (obviously, keeping the muffler out of the water) which seems to mitigate the problem rather, though is obviously not ideal by any stretch.

So, any ideas what might be causing this and if there's any affordable way to fix it?

Cheers

Start with basics. Does it have compression? Compression is higher on a cold motor.  Check spark when it is hot and won't start. Coils break down when they get hot and have weak or no spark

Well, after doing a bit of reading around these parts, I ripped the muffler apart last night, removed most of the restricty crap, and it started happily every time I needed it to today, even after putting 3 tanks of fuel through it with no downtime aside from chain love.

So, take from that what you will.

Oh yeah, it doesn't bog down any more either, even using the full length of the 14" bar, so that's nice.
