Thank you very much, Greg, Kykhayman, Burnie
and Rgx Tv, for your info and help.

I had wrapped the fuel lines with the shiny side in,
so I will take the foil out and rewrap new ones with
the shiny side out.

Greg, the fuel filter was changed a couple of months
ago, and the fuel pump just over a year ago. They may
well have sold me a poor quality pump though, lots of
Taiwanese parts being passed off as Japanese ones
in Malaysia. I"ll have to check it out again and maybe
try replacing it. I"m thinking of modifying to an electric
fuel pump.

The ignition system has been checked out thoroughly
- the contact points, condenser, plugs and plug wires
replaced. I"m using a points-triggered electronic ignition
unit made from a kit, the Motorola IC similar to the one
used in the older GM high energy ignition systems, and
it appears to be working fine. The ignition coil has been
replaced too.

Initially the distributor"s vacuum advance was a source
of the sputtering and stalling, but that has since been
rectified. What happened was that the original vacuum
pump had given way, and the only replacements here were generic "Century" brand units from Japan (or so
the label said). This advance unit has a plastic adjuster
screwed in at the end for fine timing adjustments, but it
was not heat durable (unlike the stock unit) and virtually
disintegrated after just a few months, and the ignition
timing nosedived when it did. So I managed to fashion
a copper adjuster and screwed it in, and the timing
is holding out well so far.

The fuels in Malaysia are 97 octane "premium" and
92 octane "regular". Both are unleaded, and contain
benzene (a carcinogen actually). I am using 97 octane.
Might switching to 92 octane help with the vapor lock ?

The carburetor is very basic really, the only hose
coming out goes to the vacuum advance. There are no
emission controls requirements in Malaysia, at least
for engines built in the 80s.

RGX TV, er, how does one use clothes pins for
vapor locking ?
