Before I bit the bullet and took my carb apart, I tried using gas to get it to idle. As well as being a crude work-around for my current problem, this could address general issues with fuel dilution on startup, and MIGHT be usable as a performance booster with a diesel.

That volume of gas probably isn't going to make much difference to a car (though I have a 125cc motorcycle...?) so now I'll have to scale it up a bit.

I knew it needed scaled-up, but I tried it on the car anyway.

I decided to leave the clips and wing nut off so an explosion was "only supposed to blow the blahdy lid orf".

It wasn't running at all well and I thought it probably needed the carb stripped and cleaned, which I was putting off. It started on the lighter if it was left long enough (gas probably pools in the intake) but then needed accelerator to keep it going. I suspected the idle circuit was blocked, so expecting it to actually run on a disposable lighter was a bit unrealistic.

VERY unrealistic if the sums I belatedly attempted are correct-ish

1 volume of n-Butane requires 6.5 volumes of Oxygen

www.bh-f.com/products/airgas.html

air is 21% oxygen (say 20%)

1L engine at 1000 rpm.

4 stroke so its pumping 0.25% of its capacity/rev ie 250mls.

So in a minute it shifts 250X1000 mls of air

i.e. 250 litres

a fifth of that is oxygen, ie 50L

So stochiometric combustion requires 50X1/6.5 L of butane a minute.

7.692 litres of butane

Model 1a delivers 11cc in 20 seconds, so 33cc in a minute.

so it needs scaled up by a factor of 769/33, or 233X

Motorcycle only needs scaled up by 29X, and its idle circuit isn't blocked (or wasn't last I checked) so it doesn't need to actually run on it. I havn't calculated required volume to richen it though, (maybe 10% enrichment) so maybe only 3X, which but does seem potentially attainable with lighters or small torch, with a bit of trial and error.

Going "live" on the car, I mated my brake bleeding enema syringe (Mityvac my a***..er..as it were) to a gas blowtorch, more or less closing the rear off with wadded plastic bag.

Running a bit of rubber tube (couldn't find the more rigid PVC brake-bleeding tube, which would have been better) into the air intake and turning the torch on full, it would idle by itself, which it wouldn't before.

Couldn't get the bonnet (hood) closed though, and the starter solenoid contacts were just underneath the cylinder, resulting in some substantial sparks. (Hmm...shorting with a gas canister...good plan)

So I moved it to the front bumper, (fender) where it helped me limp the car home.

However, ALL vehicle modifications are illegal in Taiwan, and thats not a very discrete one, so that concludes this round of testing. I'm stripping and cleaning the carb, so the car may never run again.
