Well the 250 has had a clean - still looks pretty shit as its old Plastic Coated.
I had one of my engineer buddies fart up the missing parts for the ignition (big ups to Daryll)

Spent all day last sunday wrapping a rope around a rear tyre and trying to pull start it with as much as a backfire every now and then.
Fuel was leaking from everywhere - carbys, fuel pump, out the exhaust from it over fuelling, and we still didnt now if we had the flywheel in the right spot as the old part that was missing was keyway'd on and the new one isnt.

Decided to bleed up brakes - found ATF in all the lines and cylinders - GREAT - bleed that all out and filled/bleed with new fluid now has brakes.

Retire as was getting sore from all the tugging ;) ;)

Yesterday - Went back round to dads in the morning and he had stripped, cleaned and rebuilt the carbs, all new fuel line and clamps etc - yay no more leaks. He also made up a tool to find TDC - a drilled out spark plug, tapped, with a bolt through it - so we couuld wind it in, find TDC and wind the engine back a bit with the bolt to hold it while we cranked the flywheel up in the right spot.

Had to work out better way of starting - we had seen those rollers you put under 1 ute wheel to get race motorbikes going - so backed the 720 up jacked a wheel off the ground, stuck it in third and pushed the kart tyre backwards against the ute tyre - woohoo easy starting.

Still no go until i choked it i bit and it started to run on 1 cylinder - smoke only out 1 pipe.

Eventually worked out had crook spark plug - two new ones and BAMM

THE MIGHTY 250 NOW RUNS AND REALLY WELL.

Just finishing off some cosmetic and safety thing including kill switch - then to big car park for test run hahahaha.

I've seen this thing in the flesh. And I have to say that it looks only slightly less safe than being in the mile high club with a junkie whore over a war zone with a pissed up pilot and carlos the jackel sitting right behind you! (Stole that one from an old videogame advert, but you get the idea)

Lasted around 25 laps on the saturday and was blisteringly quick ina straight line, no traction out of low speed corners, then the damn this siezed - i knew i should have stopped and checked the plugs - was only slight nip up and had almost detonated a hole though piston #2.

after taking heads and barrells off on sat night found other barrell was cracked in two places umong other things. have spare barrells but now on hunt for another engine as a standard one will be more reliable. and the ports on it have been opened up soo much the walls are paper thin.

there was around 30 vintage karts for the lunchtime display for both sat and sunday somecoming as far as chch. Haad an absolute ball and will keep hold of this as people were trying to buy it all week end as they new or new of the kart and original owner.

Such a variety of Karts 2 with some running McCullocks or 2 on some karts with one or more (up to 3) carbies on each motor (the thing they got up to in the day).

Dads McCullock went strong and even Brendan (Mint16) had a run on sunday and is now trying to find one of his own ex race vintage karts.

Will put up more vids as i get them loaded up.
