Wet plug

[phattanglo]

So the moral is, if you haven't used your scoot for a week or so, don't run your engine for 10 seconds the night before you need it especially when it's cold.

Cos what happens is you end up with a really wet plug that refuses to work and after much coarse language and entreaties to your preferred deity you end up having to use that crappiest of crappy old plugs in the bottom of your toolbox.

You know, the one that would be better suited as a fishing weight.

So remember don't put your spare new plug in a special secret place then forget where that is.

Put it in your glove box with all your other essential crap.

And remember as with all spares, you will never need it until the day you leave it at home.

I once stopped and helped an ol boy out with a smallframe Vespa. His was running a sh*tty plug, so I gave him my new one out of the glovebox.... Two f**king days later, guess what popped.... Guess what I hadn't replaced...... Pushed the dam thing nearly 10 miles that day..... Now usually I carry two plugs.....

To conclude this episode, I've always felt like I've struggled with the jetting on my scoot as if something just wasn't right.
So gathering carb cleaner, tools and a pre cat throttle slide I removed the carb and stripped it.
It was actually pretty clean and no blockages but one glaring problem was the pilot adjusting screw.
T'internet and Mr Haynes say don't screw it in too tight as it may cause damage.
The problem was the thread in the carb body had a tiny bit of damage so when I screwed the adjuster in until feeling resistance it was nowhere near far enough in.
I managed to polish out the damage out with some solvol autosol on the thread and screwing it in and out until it would screw fully in.
Result is a scoot that blips beautifully a la mista freak moped, ticks over like a ticky thing from tickover land and pulls in the lower rev range better than it ever has.
I drilled the air filter as well, but it's too early to tell the benefit yet without plug chopping, but it doesn't seem to have had a negative effect.

Before this I'm amazed that it ran at all.
Well next on the list is the brake calliper that seizes at the first sign of a British winter.
At least Vespa ownership keeps you occupied.

I thought that was normal behaviour. We all do that after all.
