ErmmYup me again .
You know the drill VW 1600c and Snowmobile clutch drive.
I have 64 X32 wooden two blade prop and a composite three blade 59" with 10* pitch blocks.
Both spinning at 3100 rpm at the prop and 3200 rpm at the motor.
Which one should give me the Most "Push"
Don't care about " Hole shot".

Headers on the bug.
With the new little welder I'm plugging along.
I made some headers for the bug motor.
The easiest way was to use the existing pipes and ad
crisscross   Pipes. They point out to the side right now but will
point to the back, I have the mufflers from the "Johnson" jammed on now and they make the bug quite quiet. I'll work with them .
 
 
I did some digging and found out I have my distributor "Plumed" wrong.
When I got the carb I used the vacuum lines that where on the old one, used them by size and they seamed to work.
But on a VW they put vacuum on both sides of the advance diagram
and I had them backwards. AND come to find out In my application , I need to uncap one and leave it to atmosphere and plug it at the carb. Then , this is odd, I have to find TDC of #1 mark the pulley where you time it from mark the Degrees to 28*.
Run the motor up to 3500 rpm and set the mark to 28* Above TDC. I also found out an old fashioned distributor with mechanical weights would be the best in my application. 
I'll have to look in to that if I cant get it to 28*.

What you need is dual point distributor, you leave it retarded enough to start easier, then as you come up in rpm, you hit switch for second set of points and it advances your 28 degrees, to get the high rpm and pump some fuel on through.

That used to be the hot set up, before computer tunes and even before going to twin magnetos. That along with the heavy weights and light springs, controlled how much power, you put to the ground or prop.

Ok ! 
I re plumbed the distributor as directed, and left off and plugged the second Vacuum line.
I used a  * print out , worked great.
I found TDS on #1 marked it and took off the prop.
I fired it up with the timing light on it.
Ran it up to 3500 rpm and twisted the distributor till I hit
the stud that was used to hold the old manual fuel pump( I have it capped off ) and use an electric fuel pump.Not quite to the 28* mark with the vacuum line off as needed .
I was able to cut the stub off some to let the distb. turn farther.
I set it to 28* clamped it down, and put the vac line back on.
Put the prop back on and...
PERFICT!!! I now have enough HP to turn the prop up to the required 3100rpm.
That's all ,but it is right on 3900 rpm on the motor and holds . Nice.
I have a very short Video of the boat moving , on the snow.
Still lots of work to do like some way to steer , cage ext...

Bear, I was trying to get it stopped before we hit the 4wheeler.
 The accelerator is a string and it's up front I had to be able to pull it .

Started the cage for the prop and drive.
 
 
 
 
 
 
 I'll have three "Hoops" I want to cover the drive unit too as well as the prop.
I'll have a removable screen over the motor also .
I gave 2 1/2 inches for movement and in the event I go with a bigger prop If I hop the bug up.
That gives me 3" to spare to get out of the shop I may not be able to get it under the boat port on a trailer, Dang it.

I would add brace here to cage, to keep it from wobbling into prop.
