Download the manual, read it. Stripping and cleaning carb is one of the easiest jobs to do on a 2stroke bike.
Meccano is harder to get to grips with than stripping and cleaning a carb. Don't let it scare you - it really is easy to do... otherwise, I'd suggest selling the bike and getting a 4T, as any regular maintenance that is a necessity for a 2stroke bike is gonna scare you, and you're gonna end up forking out hundreds in labour hours to the local bike shop for tasks that really you should learn to do yourself.
Grey residue is likely result of water mixed with 2T oil saturating / flooding your spark plug as you have water in the float chamber that is submerging the main jet (main jet is in base of float bowl, and petrol floats on water), so when you open throttle, bike gets a lung full of water rather than fuel.
Flip up tank. Turn fuel off. Look down at carb. Either side of it you'll see 2x jubilee clips clamped over rubbers. Undo those. Grab carb... move it backwards and forwards and work it out from between the rubbers. Keeping it the right way up, undo big brass bolt in bottom. Bottom will then come off. This bottom part is the float bowl. Ideally, open the bolt over a glass bowl so that you catch the spilt fuel and can inspect it for signs of water or contamination.
If no signs of globules of liquid suspended in fuel, inspect the bottom of the carb that you removed for signs of contamination - dust, rust, dirt etc. Rinse it out.
The jets are small brass things with a hole in the middle and a flat-blade screwdriver cut - you'll see em. Take them out one at a time, blow thru them, rinse in boiling water. Put em back in again. Tighten em til they nip gently.
Put float bowl back on. Do up the big bolt to secure it in place. (Note, this big bolt has the main jet fitted in the opposite end of it).
Fit carb back in between the rubbers. Put the jubilee clips back on. Turn on fuel tap.
See if it starts. See if problem still exists.

CARB SETUP
Set it to rev at 2000 with the idle screw, then twiddle the air screw just to the left of the idle screw... turn it all the way in, then back out 1.5 to 2.5 turns, listening to engine. As you turn it, revs should increase slightly. Set it to a point that revs are at highest and smoothest. Now use the idle screw to tune it back down to around 1100rpm ( i normally set mine at 1500rpm )... that should be the carb as set as it can be.
in = increase
out = decrease revs

REGULATION OF IDLE
This regulation must always be
carried out with warm engine
and throttle closed.
Operate as follows:
- remove the right or left-side
fairing according to
instructions on page 14;
- tighten adjusting screw (1) of
the fuel valve to obtain a high
speed rate (2,000 RPM; by
turning clockwise, the speed
increases, by reversing the
operation it decreases);
- tighten or loosen screw (2)
that adjusts mixture dosage
until getting regular engine
rotation;
- progressively loosen gas
valve adjusting screw (1) until
reaching 1,000 RPM.
- reassemble the side fairing.
At high speed fuel mixture
dosage is automatic, and
cannot be opened from the
outside. Should the engine run
irregularly, clean the carburetor.
