Dominant 371

Scuffed it with some 320 grit.

I been wanting to try one of the emery balls

There's power in the lowers. You don't want to cause turbulence into the transfers. I did one with now machine work thst hit 180 and I'm at 1100' elevation.

I'll keep that in mind Mike. I've had this saw apart a half dozen times since I built it so I'm sure today won't be the last.

They work well. I've used them on dirt bike/ ATV cylinders.

I have some Scotch Brite hones I forgot about.

They r pretty $$$ though

Yup.

Carb mocked up. Impulse is way short with either one but that's an easy fix.[emoji4]

Guess I'll start with the rwj..divider is pulled.

Put that divider back in and run it. It should tune a little better with it in.

With the divider in. There should be more velocity going over the jets and pulling more fuel.

At least that is my thoughts.......might be way off base.

Initial compression. Very lightly oiled piston/ring. Also a little proof it's in there. Lol

What was the squish between the two different pistons?

I liked the tillotson more better on mine. Need to find one for it.

I'll try it. My 385 seems to like it better without.

Not gonna lie Brian. I slapped it in and ran it. I know the meteor was .020-.022.

Here's the video. I have to apologize in advance for the poor camera angle. My wood pile is a fuggin disaster but you get the idea.

Well that didn't work...

 

[beaglebriar]

Try this...

I'll try the Tilly after I mess with the walbro some more. The 385 boot is bigger so it might be causing some fuel puddling.

I did one in my 353. Gained about 10psi, it's a welded pop-up.

That's with RED ARMOR OIL correct?If not you can gain 40% by running it mixed 90:1 with kerosene....

[Termitebuffet]

It sounds good [emoji106] [emoji106]

Try this...

It sound's good seems to have good torque.

Is that a 385 tilly carb.

I'm using the walbro now but yes the Tilly is a 385 carb.
