You stupid boy.....!!

Here's a clue....
















Been listening to re-runs of Dad's Army

Think I should be auditioning for the part of ("Don't tell them your name") Private Pike.

So.....

Pulled out the beast, set the RH carb to match the left hand.

Turned it over in full confidence of an instant start.

Nada.  Nein.  Non.  Nichts.  Non. Null.

So before I ran out of languages, stopped and had a think.

The throttle cables seemed a bit tight, no play, maybe the slides aren't home.  Fiddled with both cables got slack back (problem in twist grip cable seating).

VOILA!!  instant start.  Followed by sudden death of LH followed up by demise on RH.

Checked sparks and timing.  OK.
Let's see what the fuel looks like in the carb.  Maybe they are gummed up with the gubbins that was supposed to seal the tank?

Took LH carb off first.  Not much fuel in there at all.  What there was looked a funny orange colour though.  Will have to think about that.

Took RH off.  Same story except the fuel looked a bit less coloured.

Opened fuel taps to look at color of fuel in tank.  NO FUEL CAME OUT!!

Felt a bit fuelish.  So I put 2 litres in, checked colour through taps, clear and no sediment.
Re-assembled everything.  Pressed the go button.

KABOOOM!!   Two hot pots!!  Felt ok on pick up so took her out for a spin.  Ran pretty well on choke.  Felt very weak off choke - nothing low down at all. Would pull away only with high rpm clutch slipping.

BUT NO KANGAROO on-off effects, no spitting and popping at all.

Brought her home to start work on carb tuning, but then it rained so left it at that.  The spark plugs looked a bit dark as if it was rich, but in truth the test run was way too short to get a useful reading.  But definitely no unburnt fuel out the exhausts now - unlike before the new ignition.  And both cylinders seem to be up to operating temperature (last year LH was always cool)

Excuse alert;
In my defence, the glass reservoirs in the fuel line (containing the secondary filters) had appeared to have fuel in them so I'd assumed all was well on that front.   But once the tank is empty the fuel in the line just hangs there without flowing into the carbs.  Deceptive.

And finally;
I'm going to need a new helmet those old ones just don't fit properly.  They are 30 years old!!  The prospects for a ride to an MOT before winter look promising.  Hope are up!
