Spuds Porting and Tuning Thread

[spudulike]

Oh. Crap.

 

I ca drop mine in on the 18th if you're about?

 

Should be OK but text me nearer the time:thumbup:

I thinks its good manners to give it a bit of a clean before you send it to someone to work on it .

 

 

You are correct, I was leg pulling, I did drop off a dirty saw once🙈 Spud gave me the schoolteacher to naughty boy look.

My neighbour did his motorbike calipers in the dishwasher recently with good result. A long time ago in the bench thread I think it was, we discussed the merits of household appliances for shed purposes. I got banned from using the oven to heat up crankshaft bearings ever again or using it for any non food purposes.

 

Spud , id only put the plastic bits in the dishwasher. Don't imagine salt and corrosive chemicals good on the carb or engine itself.

Hi Steve,

I'm after a little guidance on carb tuning.

I've fitted a dual port muffler on my stihl 066 and I'm concerned that without a tune up I risk leaning the saw out.

Do I tweak the L out a touch and leave the H screw ??

I had to tweak the H screw on mine when fitting the dual port. Sounds better and stops the flexible chain brake handle.

It was sounding a little too racey so I've turned the H and L out a 1/4 turn. I'll swap to a new plug at the weekend and keep an eye on the colour until I call in to the saw shop.

Revving it up without my ear defenders on and my ears are still ringing 15 minutes on!

The joy of dualports. Keeps nosy individuals away

I would retune both but it is only the H screw that may cause damage. I would just tach the saw to 13000 - 13500 rpm, without a tach, give the H screw a 1/4 turn anti clockwise and check the plug colour after an hours running - it should be coffee colour!

 

I would be concerned about just putting on a dual port without any retune!

Great! Thanks Steve. I've opened both H and L a1/4 turn so I'm on the right tracks at least.

I'll get it tached on my next visit to the saw shop now I have the right figures 👍

I'm about to pull the trigger on a new 201T Spud, any recs?

 

Better and more durable than a 540?

 

My 200's fine, but my backup 020t AVE's still a bit temperamental at times, but still screams!

 

Do you trust these microprocessor driven new saws like the 201?

 

I run very high octane racing fuel, mixed with stihl's silver synthetic mix.

 

Thanks for any advice mate.

I did read somewhere the very high octane fuel wont make the engine run as well as lower octane fuel unless you have the higher compression to make it combust properly .
