If we were all ambidextrous, had bidirectional foredom motors, and both left and right burrs, I’d bet wash patterns would be more similar. But even Stihl staggered the transfers from left to right for some reason, so most every 2 port will have a non-matching pattern

I feel that heat plays some roll in the wash pattern as well.

Chainsaws prove to be more difficult to get perfect wash patterns. It does happen, but near as consistent as the larger more efficient 2 strokes.

It's much like how our toilets swirl in one direction and down under, they swirl in the other direction.

Seems fishy to me

It's there to see on the Stihl Swirl-O-Chamber diagram.

Have you put the spark plug in and seen how it’s indexed.

It’s just a thought that it may well play a part in your wash pattern.

Perhaps I should send it your way Steveo to see if the wash pattern transposes?

Seriously now, I appreciate all you lads replies, tbh I wasn't too worried about it at all, just thought it would be a good conversation starter, after all I am resurrecting a dead old thread!

I'm more concerned about the consistency of my own wash pattern....at least once a day... otherwise my wife complains I smell like 'old lawnmowers' and that isn't a brand of aftershave I can assure you

I haven't Sean, but I certainly will have a look. The sparkplug is still in the cylinder.

It has cleaned the vast majority of the top of the piston off, which is more than you can say for most.

Somewhere in the depths of this forum is the pic/vid of the Stihl swirl pattern they bragged up at that time.
It was a real thing, I just could not see how it swirled the one way and not the other at the same time.

Here's the indexing, the gap is towards the PTO side of the cylinder

I don’t bother checking wash unless the plug was indexed right.

Thanks Mason, what would you consider to be 'right'?

With the ground electrode at the roof of the combustion chamber and the gap open pointed to the piston.

I have never bothered with indexing a plug in a saw myself but I do unshroud the plug only takes a minute with a file. Have I tested results in a lab no but my saws run good.

 

[rogue60]

Like this file the ground strap back so it exposes half the center electrode

Dibs on the German bosch. The new chinesium bosch plugs stink.

Thanks Rouge, interesting solution! I never thought of that. I use Japanese NGK's which I find very consistent.

Hows Aussie? You're Brisbane way, aren't you? I follow your posts with interest and I recently picked up a very early 088 with the cast muffler, unlimited coil, and no limiters on the carb just like yours. haven't had a chance to give it a good run yet though....

 

[Rogee]

Yes are they a copy or did Bosch start making them in China. I had one melt the centre electrode in a 576 husky . Wondered why it was getting a little slow starting
