1.2 carb wont start

[nova-taken]

Hey guys

just put the engine back into my nova, everything looks ok and its wired properly, but the bloody thing wont start!!

i have a spark, i have fuel through the carb, and its firing.

but it will not start for love nor money.

any ideas??

any useful info will be repped :thumb:

Do you have "enough" fuel though? fuel pump could be goosed. Timing ok? Ht leads fitted correctly?

[Novasport]

Earth lead fitted from N/S chassis leg to gearbox?
Timing OK?
Dizzy OK? Module in the dizzy often packs up.
Do you have compression?
Start with all the basics again and work your way through.
Is there trace of fuel getting into the cylinders, any on the plugs?

i had this on my car the other day and was ht leads in wrong order double check them

[nova-taken]

all earths are fine, checked and double checked.
timing has been set and reset and checked and all is well
tried new dizzy, and cap, and coil.
plenty of compression.
and have taken plugs out and turned it, and petrol is getting into the cylinders
and ive check the ht's

im clueless as to why it wont start

[Novasport]

Get some Easistart ;)

[IVI0USEY]

mine are now in this order
1 top left then 3 bottom left 4 bottom right 2 top right

number is cylinder position on dizzy looking from passenger wing

thats order that made mine run?

[nova-taken]

yeah, if i cant get it going soon ill have too, id rather get it running on its own steam, but if it needs help so be it lol

@IVI0USEY, thats the order mine are dude but all help is appreciated

get a tow rope. when my old one still had its carb engine, i did some work & it simply wouldn't start. we towed it up to about 30 and bump started it. maybe the battery wasn't properly charged, but it ran fine from there on.

[nova-taken]

ill have to try that mate, hope it starts soon, starting to lose my enthusiasm, which means hammer + windscreen which would be quite unfortunate given all the work ive put into it

[John]

have you checked the fuel pump?

[nova-taken]

yup, fuel pump is fine :(

[mowgli]

cambelt not slipped a tooth?? or the choke cable not set right?

[nova-taken]

nope, timing is fine, ive checked and checked and check it, choke cable is adjusted according to haynes.

i am clueless now, ive exhaust every option and still, its firing nicely, but will not start

[IVI0USEY]

compression test?

[mowgli]

the distributor on the 1200st has an advance retard diaphragm that can fail, so when you are trying to start, it doesn't actually advance it. to test it, you need to partially dismantle the dizzy, ie. cap off, arm off, cover off, and then pop the vacuum pipe off the carb & suck like hell on it, and see if the mechanism moves or not. that could be the problem. advancing the timing will sort of fix it, but not properly....

ive sorted it now guys, after a long time potching with it all day ive finally got it running. the carb was set up all to f**k!

finally.

taken long enuff mind

thanks for all your help guys, rep will be added :thumb:
