G'day Guy's,
Had a heap of fun getting my MS390 farmboss chainsaw to go after dying on on me cutting wood, tried to adjust the carbi but went too far and couldn't get it to start. So decided to look online and found a great site . Reset the carbi and had the chainsaw going in no time and tuned nicely.
Very handy thing to remember too if ones owns chainsaws

Cheers Bryan

Good find Bryan.

Same technique could be used for 2 stroke whipper snippers.

Adjustment by sound looks like good idea.

Often getting engine to start is the biggest problem, sometimes I helped myself with heat gun, by blowing hot air on engine for few minutes.

I could swear it helped and later I always used heat gun without even trying to start without it.

Ok I'll go thru the procedure I did with getting my MS390 going. First I wound all 3 secrews right home then went back one turn on the mixture screws. It didn't start so wound the throttle 3/4ers out and got it to fire but it was too quick so winding the throttle in 1 turn got the revs down and it was purring along. On acceleration smoke was present so tweaked the low mixture screw and that fixed that. On revving full bore smoke was also there so tweaked the high mixture screw to fix that. Finally adjusted the idle and that was it fully tuned.

I cut down 2 dead trees yesterday, went thru 3 tanks of fuel and it didn't miss a beat.

Now while I'm on the subject, the sharpening of the chain is the most important thing. Every time one sharpens the depth gauge does need to be filed down or the blade just won't cut. Go down too deep and be prepared to hang on as the chain will rip thru the wood like a sword going thru butter. I did go a tad deep with my chain and found when starting one has to be aware as it it want to walk but once the cut starts it rips thru the wood easily. Provided one doesn't hit a rock or nails etc the chain should last last for ages too. For checking the depth of cutting gauge a straight edge sitting on 2 corresponding teeth (the same side) will show the depth. Ideally 1.5-2mm is the best depth and if one is adventurous try 3-4mm.

A mate up north taught me this and I do feel knowledge like this should be shared and not kept on oneself.

Cheers Bryan

Thanks for that info Bryan ,,

My Husky --- a timber cutter told me not to use standard fuel,,use the high octane fuel.

Also, I found that cleaning the air filter every tank of fuel makes it start and power much better-- a dirty air filter is the cause of most problems..

Yep, keeping that chain very sharp is absolutely essential,thanks.

Hope you are going OK down there ,

Thanks for that.

G'day Guy's,
Well in between jobs and $$$ was getting tight so put signs up around local places and not one phonecall in 3 weeks. A mate suggested joining the local FB group chat so did that last night and got an order today so yea first one sold. Called into the local and talking with mates got another order for tomorrow with the local 5MU radio radio host. The lady I sold that first load to did say when I get onto my mates you will be one busy boy.

Anyway gotta say the 390 is going great and with 2 tank loads yesterday cut over a ton of wood and the blade is still good to go for a few more tanks.

Needed bar oil so went for a drive over to Balhannah Stihl branch as the Mt Barker one can go jump as far as I'm concerned. Talking with the guys there about the way I retuned the 390 the guy went and looked in the book then came back and said well mate the way you did it isn't the way the book says but I fell you have a better way of doing it. We got talking on sharpening devices and I mentioned going off their design I can make one more rigid and cheaper than the book price. Well they said bring it on in and we may stock it.

Anyway took a pic of the pantek this morning.

After 4 loads the rear right side gave way with a nice sound so it won't take long to empty then I'll set it up again on the main supports.

Cheers Bryan
