engine missing around 3000rpm??? :S:S:S
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.
I dream of a day when a chicken can cross a road without being asked for it's motive!
