How does it feel compared to your 036?

He measures his finger ports for width and depth.

I just put the good eye on em' o_O

I lack patients
Yeah I don't spend much time making my stuff pretty. I tear them back apart and polish later if I plan to sell. I hate to spend an hour on making them slick to go back and grind away on them.

Because Al is a perfectionist! Have you ever seen close up pics of his work? It's some of the nicest that you'll see
He sure does awesome work. I have photos on my phone to show my buddies what has been done to my saw after they run it. One has a new MS362 that was thoroughly embarrassed by Al's handi work. Too bad you can't see his work from the outside. I'm still waiting for a sticker though.

We will run both on Friday. Two things I didn't do, clip the lower transfer lip and add bridges. This jug came one at an 84-85 intake as opposed to 82 on my other 036 and Backtrollers. I didn't want to reduce case volume any further.

If is slower, I may pull the jug. I'm at the point where I can't tell what's fast anymore. The video was terrible above. I was using a lot of energy making sure I didn't cut my Johnson off. There was side loading, diagonal cuts, etc...

I can't even tell what's fast anymore. It looks like it made it through that 16" log in about 5 seconds. I guess that's ok.

How do you cut the transfers on an angle like that? And make them equal.
David,

I spent some time really studying the factory opening in the transfers. I put a ring in at the intake opening point and measured the distance from it to the exhaust opening point. I duplicated the opening angle. My other 036's runs well at 120, and this exhaust came in more like 102ish, so I went with 118-122. I just looked at my notes and it was 118, not 117.

I put a ring in and marked at 122, then again at 118. I carved a diagonal line between the two on both sides.

All that extra work may have not done a thing. The 038 boot can be playing a role with torque, I'm not sure. It's a variable I changed but really shouldn't for testing. I wanted to copy and blend into the factory floor the way they cast it. The only way to do so was to copy their angle.

Again, I wanted to try something new. It may have not added a thing.

I don't want to leave any stone unturned. I ordered a 038 boot for mine. If it comes before Friday I'll test it out before the weekend.

I bet it slows you down Pat. The more I think about it.

Your jug was a great one with a higher intake. Come to think of it, my badass 036 has an 84 intake just like this one.

A smaller opening would cause less flow, but more velocity, and less blowback. It may be the very reason this model does OK with a low intake.

Would be interesting to see your results Pat. I put some Dirko around the boot. The outer diameter of it is slightly larger than the 036 boot.

May sure you don't get an air leak.

I think epoxying the intake floor may work really well with the larger boot.

Al I agree with your hunch, if you have a bigger tract you need to give it less time. If the carb and boot are smaller you will need more duration to make it fill the base.

To get a nice low idle and easy starting it always seemed that a low intake duration helps. I assume it is good case compression that helps fill the jug at low speed. also lower fuel consumption

ill be interested to see how it turns out.

Man, now I'm having second thoughts about monkeying with it. It runs so good now I'm not sure I want to play with it.
