What's on your bench today?

re the setting height of the 260 WTE arm.

 

Its a strange one that, but here seems to be no specified height. Although the carb is Walbro, it is unique to Stihl, so thats possibly why Walbro do not publish specs.

 

The Stihl service manuals tell you exactly how to fit the metering arm, but never mention the setting height.

 

Unless i am missing something…..

 

A mystery then!

 

Also a mystery is why they made the metering arm adjustment screw out of cheese/petals/chocolate/whatever instead of metal as normal!

to all the experts on strokers the subject being timing

 

when i were a lad and had bought an old tired field bike say a kx crosser or down to a ts125/250 suzi me and my mate was taught from an old gent cos we had no moneys so had to club together to by one etc.

 

instead of throwing money at pots/piston/rings front sprocket we use to advance the timing a nudge and lift the carb needle a notch some worked out really well some were still sad and it got me thinking does anyone or has anyone played around with the timing on a chainsaw to get it to torque up a tad" only a thought going through my blank mind lol when a saws getting tuned up or just tired out and no moneys to go all out get new etc i know its going over to a gray area where some think its a no no but has it been done ?? on a saw

spud is the man for that one. ive never done it as i get paid to repair stuff, just making it work ok doesnt really work out too well as it will be in again later. so its better to repair whats broken and send a fully working saw back. and if it istn fully working im always more than happy to sort it.

 

on another note, lets say a stihl hedge cutter comes in for a service. what would people do as a service on one. i already know the parts but its something that is against the rules to post about so just asking for a list of servoce items on one.

 

and its not anything to do with anyone on here.

This is probably one for my new porting thread but yes, I have done some of this type of tweak, done respond well and others don't.

You have to be careful to get the degrees right as too much and you run the risk of some spectacular mechanical carnage!

Look slight marks on the cylinder as well as the brown line down the piston.... New piston??

Man by the name of Goaty dropped this by - anyone want to guess what it is for as I had never seen one before - he found it in New Zealand.

 

Surprisingly, it actually works very well:thumbup:

 

Very common in the States. I dunno where mines gone to Many mechs keep one on a key ring.

Looks OK to me, what is it like lower on the skirt?

The brown bit is blow by and not uncommon and OK if not heavily carbonized. Small marks are OK.

It's just a brown line down that bit of the piston..was just taken it apart to clean it and noticed it so I thought I would ask..

I'm not quite sure what forum rules have to do with it Rich, but this is what I would do on a Stihl hedgecutter service.

 

Run it up before service and observe all functions, problems etc.

Give it a good clean outside, particularly around the carb and tank

Empty the tank and blow out. Check,clean or change the fuel filter.

Check the fuel hoses and grommets, check the primer bulb. Attend to as needed.

Check carb mounting bolts.

If it was running fine then no need to dissmantle carb, but if any problems then dissmantle, clean and re-kit carb (charged extra over service)

Check throttle cable

Clean or replace air filter as required.

Change spark plug and check HT lead.

Check exhaust firmness, check for carbon in outlet, clean spark arrestor.

Check starter mechanism and replace cord if required.

Check AV,s (if fitted)

Check handles for firmness and or damage

Check condition of blades (damage, cracks etc) check all blade bolts for tightness (making sure spacers are present)

Remove gearbox bottom cover, clean out old grease, check bearings, gears and cams, relube and refit.

Sharpen blades (I do mine assembled, no need to dissmantle)

Fill with Aspen2 and fit aspen sticker

Run machine, lubricate blades, tune carb and tach max revs, check idle

speed, clutch engagement and engine pickup

Fit 'service done by' sticker and write out bill (in my case £60 inc vat and parts)

 

hope this helps

[Rich2484]

Ok thanks Barrie.

 

Just had one in that suppose to be serviced. But old starter cord, old spark plug. Old dirty filter.

 

And blades had not been sharpend.

 

Just can't say who that's all.
