Clark Forklift Starting Problem

Here we go! Got this starting probelm with my 1950's Clark model c40mb-193-782 wondering if someone can help. Details are such.

Starts and idles good.

Several minutes or more starts to die on slight acceleration.
Seems to get worse as it heats up. As if it was gasping for fuel?

Battery new and charged.

Tried two different full tanks of Propane.

Live in Maine, first started when temps went to 10 degrees.

Took one tank inside overnight to warm, tried and same problem.

In the past, has run very good in cold weather once started.

It is warm now and still problem.

Plugs are two years old, wires are much older.

No Prior symptoms, ran great.

If I was to guess, appears to be fuel delivery?

Can a misfire, such as a fouled plug or other firing problem, cause such a symptom. Seems as though it would also misfire when idling???

Got it running this morning, ran great for about three minutes.

Stalled and now wont start.

Turns over good but no firing.

Sprayed ether in air intake, fires every time.

Checked plugs and points and looks o.k.

open gas line to carb intake and was pressurized with gas.

Checked for extra gasket on forklift to tank connector and found nothing.

Help, I,m losing hope.

Plugs dont last long running on LPG.

Wonder if the ignition coil is breaking down due to age?

Fact of the week
In March 2002, identical twins in Finland died on the same day in similar accidents within hours of each other. A 70-year-old man was killed by a truck while cycling; hours later, his twin brother was killed by a truck on the same road, about a mile away, before the family had been informed of the first accident.
