With the cowl done, and the baffles in progress, I decided to start on fitting the snorkel. I started by fabricating a spacer to fit in the inlet hole.

This allowed me to temporarly align the snorkel to the inlet. The starter motor had a lug that was interfering with the snorkel, so I removed it.

With the snorkel rotated up as much as possible, and aligned with the baffle ramp, I trimmed the sides to align with the fuel servo.

I moved the mixture knob all the way forward, and found that it interfered with the snorkel. I used my heat gun to soften the snorkel and pressed in with the butt of my screw driver to create an indentation. Once the snorkel cooled down, it was solid again, and left 1/4″ clearance around the mixture arm. I will seal the snorkel with some additional epoxy which should increase the strength in this location, incase any was lost with the softening.

With the inlet ramps installed, I was able to align and fit the snorkel to the baffle. I then drilled the holes to mount the snorkel to the inlet.

I trimmed down the snorkel to fit under the baffle by about 3/8″. This allows for enough clearance under the baffle for the servo mounting flanges to fit.

This will get fitted to the lower baffle ramp a bit more and will secure the filter.
