2TG starting problems

Got my 2TG/3TG in the other day and ive put on some solexs i havnt used for about 3 years, thing is it takes a couple of trys before i can get it started and running, but now i cant start it at all, with or without chokes open. what do you think it could be? they need a good tune i know that, but i had it running perfectly last week, also ive noticed sometimes when i put my foot down abit it starts to decelerate instead of accelerating, then just dies..
The timing is perfect on it and my point gap is set to about .5mm or a little more, that was the only way i got her running..
any suggestions appreciated
cheers.

maybe to much fuel pressure from the electric pump making it flood...
try to start it with your foot flat to the floor
dont pump it or anything
just 100% throttle till it starts

id say it's your accelerator pump.
when carbies are old the diaphram cracks and no longer squirts fuel. Have a look with the air cleanes off, look down a barrel and see if you get a good squirt like a water pistol of fuel when you move from 0-100% throttle. (with the car off of course).
This would also explan the stutter when you put your boot into it.
This also expalins the car not starting since you need to pump in a bit of fuel to get it to kick over usually. and no accelerator pump = no start.
You may just be able to buy a new diapram for the pump but i'm not too sure. you might have to buy a whole kit. Not sure how much though.

yeah i was thinking that also hemi, i tried it again this morning and no luck, no fuel at all in each throat, im pretty sure you have to buy the kits for them too and not just the diaphrams. This morning when i tried to crank it over i can smell unburn fuel in the air so im assuming its flooded? i might just take the carbs off and have a good look inside..

well i pulled them apart today and i found gunk covering the whole of the starter jet so i cleaned that all off, everything else was fine, but on the right carb i found a ball bearing lying in that little area beside the float chamber plate and it was submerged in water.. about a quarter full. i dunno how water got in there but i cleaned it and took the ball bearing out. where this ball bearing came from i dunno but will i have a better chance at starting it now you recon?
thanks.

usually balls go on the end of springs... usually 
I pulled apart a solex about a year ago and i remember
there was a ball, and i remembered i knew where to put
it, but i don't remember now 
The water is most likely from your fuel tank/lines from
when the car was sitting. Ever seen water in a fuel can
for the lawnmower or something, it beads and sits at the
bottom (heavier than fuel) so if it gets in your carby
it would tend to stay there i think.
Any luck starting it yet?
Have you got spark? as in at the coil lead/spark leads?
And if so is it big and juicy with a yellow outter, or a
little thin blue line?
With the tops of the carbies off, turn on your fuel pump and
check fuel is filling both the float bowls?
Also if there is/was water in one of them that white looking
corrosion could be gunking up the needle and seat?
One way, i cant remember if you can do this on solex's though,
is to run the carb with the top off, and watch and see if the
fuel fills it up and that the float stops the flow when full..
Generally with too high fuel pressure, or too high float level
the fuel will drip out of the jets and a rate of about a drip
every 5 seconds or so. So if it is too high pressure, or a leaking needle and seat you'll definately know it. By looking
down the barrels at the jets.
I had a problem on an 18rg where the needle and seat vibrated
all the way undone, causeing cyl 3&4 to flood like crazy, stutter, and generally made the car run like crap.. But
it still started. (2 cyl first, then they cleared the other 2,
then it ran on a stuttery 4) But it still ran..
Maybe your fuel is suspect? If you've got an electric pump,
and maybe not too much fuel, disconnect the fuel line and
squirt it into a bucket and check what it looks/smells
like?
Or maybe remove the suction line and put it directly into
a fresh can of fuel and see if it runs then?
Good luck!

well no luck starting it at all because there is no spark at all from the distributor, maybe because my battery is almost dead, also tried jump starting it but still no luck, but i did open the tops of my carbs to see if its filling up with my fuel pump turned on and it isnt filling at all, although my accelerator pumps are leaking but apart from that its bone dry up top. the white corrosion was all over the screws that allow you to pull the top part of the carb off, i couldnt see it anywhere else?
My fuel is looking good though, nice pink colour and that distinctive fuel smell really rich n sweet.
cheers for the replys
