Good work.

Carbs really aren't that bad. I cleaned the carbs for my motorbike and by far the hardest part of that was getting them off in the first place. The carb itself is remarkably simple.

That said... fcuk it, send it to an expert.

I suppose so. All that wiggling had made it pop out of where it hooks in.

I was tempted, after all I have the diagrams and that's all I had when I rebuilt the engine, but I'm positive it'll need re-jetting because of the reedvalve conversion so I didn't bother.
I think I'll have a go when I do the Blue Bastard though.

Haaaaaaaang on, the engine won't fire up and you say you're done with it?

Ah no. Come on now, That's not right. You've gotta conclude this properly. Resto that carbo and bask in the glow of a job properly well done.

As I said, it needs the timing done and probably re-jetting, neither of which I have the equipment/parts to do.

Jesus. This is like Angelina Jolie agreeing to let you shag her but then not letting you "complete" inside her

Yeah, you've shagged Angelina Jolie but you know you didn't finish the job properly and it could've ended better.

I wouldn't have shagged her. She cut off her own tits ffs!
The correct analogy then would be restoring an electric scooter and refusing to start it because it has no handlebars.

You were right. I thought long and hard and finally decided I shouldn't give up after 8 months of being fvcekd over by a scooter.
I hunted down carb servicing on youtube and watched many videos.
Satisfied that I now had enough knowledge on the subject I went to the garage on Sunday morning with a new purpose.

I remembered that I only needed a spark and petrol to get and engine sort of running I decided to check the spark.
ZERO. I have no idea where to start and no inclination either.

Game over. It's off to Wildcat tomorrow.

Sorry to have raised your hopes there.

Hey! I'm not that much of a knobhead. I'm deeply hurt.

First thing I did. Brand new out of the box. Nothing. Checked the HT lead both ends. Nothing.
At least there was some petrol on the plug when I first pulled it out so I know that the carb is working. In some shape at least.

Try a HT lead off a different bike, just to be sure?

I'm sure you've used your Google-fu and found this already, but if not - 6th post down seems like a quick bit of troubleshooting, before you get shot:

You'd only have to do that once! And anyway, couldn't you conscript an apprentice for just that bit? "Here, hang onto this end, no no, hold it right, thumb over the end, for a sec while I check something...."

Hello next door, could you pop your nipple in that plug cap please?

Anyway, the cdi unit, lead and plug cap are all new.

"To see if you have a spark, remove the spark plug, attach it to the ht lead, make sure it's grounded,
kick it over and look for the spark"

Yes. Because the plastic cowling cover was in place the plug wasn't grounded, hence no bloody spark.
I had a fiddle with the carb, turned the main thing all the way in, then out 1.5 turns as per the forum but still nothing.
My feeling is the timing is so far out it won't start. Or it needs re-jetting due to the reed valve fitted. Or both.

Waiting for a call to see if there's space in the workshop. If there's not space this week, I'll have a go at the carb on Thurs.

Can't say fairer than that can I?

So you are getting fuel and you are getting spark?

Are you getting air? Do you have good compression?

Come on, you're so close...

Possibly getting fuel. Definitely getting a spark. Good compression.

I've spoken with Wildcat and they said the following:

If the timing is out it'll backfire and snap the woodruf key. True and a nightmare because it can fall into the engine and gouge the shit out of things and you have to split the engine to retrieve and repair.

They'll check for a spark even though I said I had one.
They'll check the timing.
They'll check the carb is fuelling: giving and receiving.
They'll do a compression test for leaks around the head.

Somewhere along the line they'll solve the problem.
Then they can check the lights.

Then I can sell it.

Took it in to Wildcat.

They seemed suitably impressed at my resto.

Until they spotted a tiny oil leak from the casing join.

He tried to make me feel better by saying "It's a Vespa, if it's not leaking there's no oil in it" but I knew he thought I was useless.


My prognosis is that they will say it'll never start because of something I did wrong when upgrading it to a reed valve, or the casings are warped and will never hold oil and I'll have to strip it and fit all of the internals in a pair of casings I bought last week.

Well at least the thread will keep going.

No problem.

If I'd only seen that leak before I'd taken it to Wildcat I'd have ripped the bloody engine apart and used the new casings. The the reedvalve could have pissed off and it'd be a bog standard rebuild.

I've been thinking about starting on the bluebastard but I know as soon as I have a garage floor full of bits, and bench full of engine parts, I'll get that call to say the redfvcker is terminal.


This afternoon I shall be gardening instead.

Ok. Wildcat called.

Timing is ok.
Intake manifold (the bit where the stud snapped and was botched with chemical metal) was loose and sucking in air. They managed to tighten it so my repair can't have been that bad.
Carb is fvkced despite looking shiny outside. He asked if I'd found it in a skip.

If they can repair it then it should start.
If not- new carb. £65.

Carb didn't need changing. Couple of small parts needed changing but I only have a bill for £100 including labour.
It starts, runs, goes and stops and all the electrics work.

The scooter is finished. Thanks for all you help, encouragement and pisstaking. Couldn't have done it without you.

Join me on my next journey with the ET3 restoration. Guaranteed mayhem, fvckups and hilarious stories you can share in the pub.

Nice one.

What's the plan for the red bastard? Sell it?

You should at least ride it for a bit first to give it a chance to break down.

I shall ride it up and down the road, just because I want to feel my bosom swell with pride as I think, "yes, I built this!"

Then it will be for sale and become someone else's dream problem.
