Balls!!! Photo bucket is trying to make me pay to host pictures, $59USD per year. Not really worth it, so may look for another photo host or give up.

Okay, that sounds easy...didn't realise I could do that. Now you've said that I can see the attachment symbol below.

Got some questions about the carburetor. Pete thew in this carb; he never got around to installing it, but thought it would be a huge improvement over the original.

IMG_20170702_111711.thumb.jpg.be39dd60f0c68be08943d3cbb6f4041a.jpg

I've made new gaskets, fixed up the rusted out reed valves and found some rubber hose to connect the carburetor to the new intake.

Now, there are no easy to find instructions online...best I can find is in Dutch. So I'm picking someone else here would have used similar and maybe you could point me in the right direction?

This YouTube clip shows what I think, but I could be very wrong??? On second thoughts, I think the screw on the side is a red hearing and the cir-clip on the needle offers enrichment options i.e. move clip up/down to lean it out????

Any help much appreciated, as its all new to me.

Going to give this a go, just need fuel line, throttle cable, and oh...ignition. dam it!!! But in all seriousness its just a matter of getting those parts then 30 minutes to hook it all up.

That big screw is idle, the small screw on the side to the left of the idle screw is the idle mixture adjustment.

You tune it by changing the jets, buy in bulk cheap from AliExpress.

Start rich and work your way down in size, I'm not sure where to start looking size wise though.

 

Needle height adjusts the progression of fueling.

 

The vacuum port opens the fuel tap on a scooter, the little port is indeed where oil is pumped in on a self mix.

Wired up coil bypass. Now the funny thing is, I'm doing this because there was no spark. I tested it with the "tried and true" pull the cord with plug touching block....nothing....dead!

So wired this up, then tried disconnecting the HT wires from the plug and it literally fell apart. Yup the spark plug was rotten in the middle, so it never would have "sparked" even if coils were okay in the first place. However, I learnt a new skill (how to bypass a coil) and it will look tough with coils hanging off of it like a little V-twin!

I wrapped wires in heat wrap for protection, and drilled holes so cable ties could go around the cable to secure. I'll test for spark then remove old plug leads.

Made some leads today, fun little project where you get exactly what you want rather than some clown at Repco asking what your license plate number is and trying to find parts to match on their computer.

I went straight to an auto electrician and got the right parts off him. $20 and a steal at that!

IMG_20170705_142208.thumb.jpg.0a2cce30ff201356789386ef637ae33a.jpg

I needed one end to go on the plug, the other into a Lucas coil. To achieve this the auto electrician told me a trick which was to reverse the steel clip...worked a treat!

Apparently you can buy these...actually I did, but inadvertently ordered the wrong size. So I decided to make some instead;

 

IMG_20170707_145016.jpg

The pipe was about 15mm in circumstance too big. I welded 25mm box section to it, then cut it right through leaving a gap. 

Next was hammer time...to shrink it down to match the Lucas coil diameter.

Done! Tidy it up later with flap disc.

Hole saw cuts a perfect fit. Welding stainless to mild seams to create a bit of a porous weld, but acceptable.

Dry fitted...and I'm happy with the look it gives.

Overview from behind with new coils fitted. I figure there's no bonnet on a motorcycle; so if you've got to have it, you may as well make it a feature.

Not a lot going on with this lately. Toying with this idea for a choke lever

IMG_20170708_160044.thumb.jpg.91c63fc729b5bc7777fa698553ee6128.jpg

And made this little fitting out of 4140 to hold the cvt to the motor.

It has an 8mm hole, with allows me to use a long UNF bolt to pick up on the crank. The key way takes the torque, this just stops it going west!

I made the fake oil tank in order to house a battery for the coils (I have to externally bypass the magneto).

Initially I thought undoing 4 bolts to swap would be fine, but it's a total pain in the arse! 

Solution:

Everything is looking rough as guts, and well it is. But eventually I'll flap disc it all back to pretty.

First start up today. Turns out the 2 hours trying to start it this morning may have gone better if I'd figured out the the ignition was out by 180° earlier...but hey...it goes!
