hi all, i have a 1964 beach buggy which is having some problems running. It is fine at idle but as i am going through gears it will miss a little
around 3000rpm then it will be fine after that and as i reach around 100kmph after a couple kilometers it will start missing and lose accelleration
then i will shift down gears it will continue missing and losing momentum and rpm then continue all the way through until i come to a complete stop
then it will stall. After 10 or so minutes it will start up and the process will continue. any thoughts would be much appreciated.

Hi
I Need to know what Distributor [vacuum type??][ 009??]
and carby You are using.. {Solex 30 PICT 2?}
sounds like it may be a fuel problem...
as when You push the accelerator down [at any speed] the extra fuel should get the engine running again...
If its a vacuum only distributor - the vacuum diaphram may be leaking [worn out] and losing advance at speed..
can you read the numbers on the distributor??
----------------------------------------------------------------------------------
OR it can be a spark problem... depending on quality of parts
Coil breaking down?? at speed?
rotor button breaking down??
Condensor breaking down?? [common]
distributor cap breaking down??
Points worn down or shorting?? [common]
Main spark plug leak to coil breaking down..??
[common on carbon or silicone leads]
All the above things do fail and should be renewed
they were replaced frequently when serviced by VW mechanics back in the 50s, 60s & 70s...
BUT MY Guess is the first one...
cheers

If it starts again after a while I'd bet it's a fuel problem, mine had the same problem that haunted me for weeks, turned out to be a blocked fuel
filter, replaced that and the problem disapeared, seemed that just enough fuel was getting through till I reached a speed that required more fuel than
it could get through.

yea what he said happened tp me took longer to fix as some smart bugger had another filter under the tank
