O0 And now comes the last of the welding?

YUP

I did a no load, no prop today.
 All looked good. The clutch started to move at around 1800rpm.
 I did not have my laser tack on the hub but it looked slower then the drive.
 It starts out at 3x1.
 As I increased the motor RPM the clutches both moved, as expected, the clutches
 Topped out at 3000 RPM, right where I was hoping.
 I should be like .70x1 there ,I would guess around the top end for the prop, 3100RPM.
 I didn't run it long but It was quiet and smooth and looked to be running true.

More welding required .
IF IF IF  this year it will be a "Hard Water" test.
As in ice. Only thing open here is the river.
I'm thinking that may be an "Up the creek with out a paddle" thing
:D

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*.

  :shock:Wow! Not only are you having to be a welder, but a #1 mechanic, too.

Sure is a lot of work but the end result should be great.  O0 Looks like you are almost have it whipped, D.

You must be a very patient man.

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...

 O0 Nice doesn't even cover it, D! Will you be replacing the electric fuel pump with a mechanical one? The officials issuing the boat title and inspection used to demand mechanical fuel pumps but that was quite a few years ago and may of changed because of modern electronics.

I bought an outboard previously repaired motor that had an electronic car fuel pump installed and had to have it fixed to again have a mechanical fuel pump. The motor was illegal because of the electric fuel pump, a safety issue.

  O0 I sure do like your work!

Nope
 No inspection here. The FWP looked out the window at the empty hull and asked whatca going to power it with?
 I said a VW motor and air prop they said cool here is your Vin # and license info.
 Go pay the fee and your title will come in the mail in a week or so. That's It.
OK
 The Elc. Fuel pump stays , It is a low presser High Volume pump in the event I add another carb.
