You can't expect a saw to cut really fast with an Efco branded bar on it! :msp_smile:

I got 12 seconds both cuts on the 2153 and 17 seconds first cut and 18 seconds second cut for the 550. I may be off but I had my pen and paper out and watched twice.

that's about what I got.

Randy, I just checked mine. 130 psi cold on my Snap-on gauge. If it was my 028 I would think "huh..needs a rebuild".

I read that you were going to port yours without altering the timing numbers.....I say that the only way to get good gains from this engine is to do it just like the 562s I've built.

I ditch the base gasket and spin a popup to reset squish. Dropping the jug gives you more compression, intake and strato timing......but it maintains the relationship between the intake and strato. I feel that is key to keeping the autotune working as designed.

You can then raise the exhaust and transfers a bit.....

dont yall know. red saws are always faster.

what's the thread size of the smaller plugs?

36 sec for 2 cuts on the 550 and only 25 sec for the Johnny?

both saws hit the wood right near 5-6 seconds. The 2153 came out of the wood at 17 seconds and the 550 came out of the wood at 22 seconds in the first cut. 2153 was atleast 5 seconds faster in each cut.

I assume the 2153 is ported, and the 550xp totally new and stock! :hmm3grin2orange:

2153 had the same efco bar on it and it was sick quick!

I was waiting for you to say something :hmm3grin2orange:

God I hope so. I assumed they were both ported, I so hope you're right.

Its not like Randy to otstir:...

Don't sweath it, it was meant to be an obvious joke!

The J'red is ported with a cut squish and some carb work.....

The 550 was making it's very first five cuts in that video.

I have a video of the 550 uploading that shows it after I shut it down for a bit then went back to the log......

what's the thread size of the smaller plugs?

10mm x 1.0 Sportbikes have used 10mm plugs for quite some time now.

 

[Tzed250]

BTW Randy, my saw has about six tanks on it now, so that may be some of the 15 psi. difference we are getting.

OK.....I mixed up the videos.

Here's the "break in" video.

Lets hope not. I want my 2153 to walk away as the "hero of this thread". :hmm3grin2orange:

Very interesting so far. As torquey as the 550's appear to be in other vids, I'm surprised at how low their compression is.
