My second build thread. I put a 272 into a 2145!

Andy, your crazy! A M-21 is light, but not that light

 

[Mo. Jim]

Those are cool, aren't they. I ran Bills at the GTG and it is just cool. They just dont do that kind of stuff anymore. Hey there you go your next build!!! How bout a 4 speed 346 with a 385 top end?

I have the 346 and a 385 top end, but no 4 speed.

just draw up some quick plans and send them to mike. he can make you a 4 speed

Your case is too tight....you can full circle the crank but you need a larger intake volume space and a boost bottle.

 

[PES+]

And a 268 would be far better for your set up...you have way too much cylinder volume for your case volume

 

[PES+]

You could always get creative and reed it that would work real well with what you have to work with

 

[weedkilla]

Really? You're going to pick holes in this? Isn't that like saying the turbo on your lawnmower is too big, and you would have been better off with nitrous? Or you shouldn't put a big block in a Toyota Prius, it'd handle better with a boosted small block?

It won'work the way it is....pure physics

I got to see and run this saw last weekend and I tip my hat to Mike for his work on this type of project. Thanks for letting me run it, and to say that I was impressed would be the understatement of the year.

Thanks Mike for letting me run it.

Did you miss the part that mark says "Thanks for letting me run it"
Let's look at this differently..... It runs, cuts, idles, holds a tune, on the first try............... I say success in my book.

It may not be stupid strong, or fast, YET, but it was born last Friday......

"Your case is too tight....you can full circle the crank but you need a larger intake volume space and a boost bottle."

What are you talking about? What you wrote is internally inconsistent. A full circle crank is used to increase crankcase compression when you had just written that his case was too tight.

And the next part is redundant, "you need a larger intake volume AND a boost bottle."

And then this - "It won'work the way it is....pure physics" - OK, how about explaining the pure physics that you are referring to. And don't try and blow BS up our backsides, if you want to refer to something that Blair wrote I'm will to listen to it.

well I guess Mike broke the laws of physics

He must have tied on a late night bender as he's been all over the board bloviating.

This is the kind. Of bullcrap that causes O.P.s to request there threads to be deleted. These guys need to get a life.

Seems like everything on this forum gets crapped on any more. What's up with this place? It's not even winter any more. To the OP, I really hope you ignore Pest and carry on with your parts. The rest of us appreciate and enjoy it. Carry on!

Here's something for the two-stroke physics majors - http://www.dragonfly75.com/motorbike/2StrokeDesign.pdf

 

[Homelite410]

It doesn't bother me at all... I built the saw it runs nuff said!

 

[PES+]

I will beat it with a 30 cc saw...sure it runs but it doesn' t make power

 

[PES+]

I am not in anyway trying to dissuade your efforts just attempting to offer helpful first hand experience.

I will back away now.....

 

[Homelite410]

Yup........ It Took an MS180 for a ride!

Way too cool man! I love it!!!
