Calling All Linkert Owners

[1964 pan]

Every bike is different and every owner is different. What is your procedure for cold starting your Linkert equipped Pan?

[jdpan]

Depends on the circumstances. Typical would be.. Retard ignition, choke until I can hear the fuel being sucked in, 1-4 kicks depending on temp. Choke almost all the way open, ignition, compression, kick, fire, open choke, advance timing,, haul ass..

[1964 pan]

Damn. That sounds to easy. Keep er coming.

[Cotten]

Retard spark,
close choke,
kick twice with throttle open,
open choke, close throttle to slightly open,
ignition on,
kick,
advance spark when running.

Intermediate steps upon choke used only in cold weather.

Sometimes figuring out what "works" is tough.

gas on
choke on (throttle closed)
two kicks
choke off
ignition on
kick (throttle slightly open)

I have an auto advance timer.

[john HD]

my wla and panhead are exactly the same. also the 47 knuck visiting my garage are started as follows:

switch off gas on

choke closed throttle open

2 prime kicks

open choke to 1 click off open

throttle slightly open

spark advance set to 1/2 retard

switch on

one kick

advance to normal

open choke

ride....

common sense !

[Cotten]

Folks,

I'll admit that as 1964 pan said at the start of the discussion, every owner is different.

But all of my customers' machines started the same!

[awander]

close choke fully,
kick through three times with throttle closed,
retard spark about halfway,
open choke to one click down from fully open,
open throttle about 1/10 turn,
ignition on,
kick,
fully open choke & advance spark when it starts

Okay, I gotta ask...

When the choke is fully closed, and you're doing the priming kicks, if the throttle is fully closed, aren't you reducing the amount of vacuum available at the nozzle to pull fuel into the barrel? And wouldn't it also prevent fuel from getting into the intake manifold and cylinders?

Just asking.....

[UPSROD]

Throttle should be wide open to prime.

[awander]

Actually, kicking with the throttle fully open REDUCES the amount of fuel that is drawn into the engine. With the throttle open, the air moves at a low velocity, which can't pick up fuel very well.

Leaving the throttle closed increases the velocity of the air through the venturi(the same amount has to flow, because it needs to fill the cylinder), and the higher velocity air draws more fuel in.

That's why, when the engine is flooded, you should open the choke, and open the throttle fully, and kick, to pull in lots of air, and little fuel.

At least, that's the way I understand it.

PS with the throttle fully open there will be LESS vacuum-by restricting the flow(closing the throttle) you increase the vacuum.

Andy,

Very interesting! Your logic makes sense to me.

Curiously, the manual says "throttle fully open", but I think I'm gonna try the "closed" method.

[Cotten]

Andy!

Fuel is not pulled out of the main nozzle and idle bleeds by Bernoulli effect of velocity of flow over them.

It is pulled by the simple suck of the cylinder when the mouth of the carb is choked with a plate.

You could never kick fast enough to get draw from a main nozzle under normal conditions.

Choke plates originally had slots, and then holes of various sizes, and finally the spring-loaded poppet. This allows enough airflow to carry the charge downstream to the cylinder, assumeing the throttle is at least as open as the chokeplate, to keep it from laying there in a puddle.

If chokeplates truly sealed, the first kick would be a gushing flood, and probably a fire hazard.

Certainly most of you have hand-choked a machine with the aircleaner removed?

I find that having the choke lever on the first notch and kick while holding throttle closed as my last kick before turning ignition on helps.
