 2t Start up issues ... help!

Hey guys,
Ive got a 75 TA22.
Engine starts first time cold no worries, but after driving it wether it be 5 mins or a half hour it wont start again.
as in drive for 5 ... switch off... turn key wont start.
come back in 20-30 mins and it will start with minimal fuss.
New plugs, leads, oil, oil filter, fuel filter, air filter, fuel lines, coolant, points.
Ive been told could be starter motor, alternator and timing.
Any ideas?
Cheers
Nathan

When you say it wont start do you mean wont crank or wont fire?

fuel pump stuffed?
also, return line to tank (from fuel pump) blocked so excess fuel bled back to tank doesn't get there and eventually 'stops up' the main line.
also, tank-breather-to-charcoal-cannister may not working so as fuel pump sucks fuel from tank, vacuum forms preventing fluel flow - fix by re-enabling tank vent+charcoal cannister thingo.
can't be starter motor if it turns over the engine
why alternator? charge light would be on if it was stuffed - and you'd get flat battery after a while anyway. timing? did you static time it before re-installing points?
check that you're getting a spark when you crank the engine (when it refuses to fire up).

had the same problem in rona....To fix it i tossed the engine and put a new one in  But i think the problem with the other one was to do with either timing or the points them self

has it got a resistor off the coil ?
Sounds like what mne used to do .. it had no resistor ..
thing would crank and crank till the battery went flat but wouldnt kick over
Put in a resistor - and first kick everyt ime - always started
I was alsways frying points too before this

thanks guys ill check all that out.
i pulled the sparks out last night and they had black caron build up on them. The plugs are only 2 months old and the car has only been started a handfull of times in that time.
the haynes book ive got said its the plugs are in the right temp range so i got a different set today today and will see if that helps.
its not fuel because i had a mate round and he starve stalled the carby (clamped fuel line) and it started after a second with no fuel in the carb at start. also covered the air intake on the carb so it stalled full of fuel, and granted it spluttered a bit it still started. so from that im assuming its not fuel related.
if i unhook the carbon catch can will it start properly? or wont it start unless hooked up ? (to see if thats the prob?)
might i add this is my first venture into mechanics so although im pretty cluey you could still say im a novice.
Cheers guys for all the info
il keep yas posted.
Nathan

ok on further troubleshooting this is what ive come up with:
i have replaced: points, plugs, rotor cap, dizzy ballast/condensor, and coil (bosch gt40rt)
had my father in law adjust the timing by ear ... he's wise i trust his work ... plus it idles/runs better now.
the thing just wont start after taking it for a run. id drive 1 maybe 2 kms, park it, turn it off, then try to start it.
voltage readings at points like battery coil and pre coil resistor are the same as cold start before running the car.
bout the only parts i havent replaced in the ignition system are the pre coil resister and the distributor itself.
seems like driving is causing something to overheat and not allow the car to start.
also would not having the auto choke on the carby hooked up affect anything much besides making cold starts easier?
thanks guys im really at my wits end here.

are you sure it's only the auto-choke that isn't hooked up? there is normally a fuel cut solenoid wired into those carbs.
have you tried another starter relay? normally they work in conjunction with the starter moter, but if they a knackered, they won't open and won't send any power to the coil .

would a faulty relay play up all the time ?
cos it starts, just not after its been driven.
any hows im taking it to a workshop tomorow to get it diagnosed.
im putting it down to something in the carby... maybe gradually over fuelling flodding the carb and fowling plugs.
it used to take about 20 secs of cranking to get it going after a drive but now it wont start after a drive so i assume what ever the fault it has only gotten worse over time.
thanks for all the help guys, very greatful

HELP!
after starting it on sunday after replacing the ballast, it did the saem thing ie: wouldnt start after a drive.
go to start it monday night to drive it to a mechanic for the next morning, and nothing ... no spark at dizzy.
no voltage if measured off coil + and - but if i earth off body and use +coil it gets voltage.
after checking this and that it suddenly has spark....but its too late at night and my battery pack is dead  ]
i also heard a few clicks from the dash drivers side.... are there any relays up in there?
Cheers

hey would an overly rich mixture at the carby (ie set via the mixture screw) be rich enough to foul the plugs in a 10-15minute drive ?
or would that sort of over fuelling be more likely to be a fault within the carby rather that an over adjustment?
cheers

sounds like coil wiring to me. there is a wire that connects to the dizzy from the coil, it screws into the dizzy at the same point where the dizzy/point condensor goes. had the same problem and that wire was stuffed.
also the solenoid may be the issue too, what you can try is while trying to start it get someone to lightly knock the solenoid (dont hammer it), if you dont want to try that and you wanna check if its faulty then un screw it and with reds on plug/unplug it and you should hear a ticking noise, ie, the solenoid moving forward and back.
if that fails then it really does sound like coil resistor overheating and failing, once resistor cools it starts (MOST LIKELY CAUSE OF PROBLEM)
as for everything else the guys are right, cant be starter as it is kicking, not alternator as that would prevent car from starting just battery wouldnt charge and no matter hot or cold it wouldnt start after that, cant be fuel as it does start, but do you get any problems while driving? sluggish, jumping, cant floor it. i find with that motor and mine (have an imported 3T carby) that you need to give it a good thrashing for a minute to help clean the carby and combustion chamber out a bit
