Pulse line on a Marathon 295 cc Robin and Carb qeustion

[Activate]

Hello,

I have a Marathon 4 cycle with the 295 CC engine.

Someone has changed the fuel tank and removed the fuel pump.

Now it is running bad and I think that is because the fuel pump is missing.

I want to buy a new fuel pump but I don not know where the pulse line on the engine is.

Witch fuel pump do I need and where is the pulse line on a 295 cc Robin engine?

A picture or drawing from the pulse line would be nice.

There are also two(vacuum?) lines on the side of the carb where the fuel line is where must they connected to ?

Also a little needle in front of the carb, it can be adjusted what can be adjusted with this needle?

Thanks and greetings,

Erik.

There are 2 - 1/4” inlets... one on the carb feeds the float valve... the other is on the block and it’s the pulse line... the two smaller “vacuum” lines are actually overflow and vent tubes... they just hang... then there’s the larger PCV line

This is the pulse inlet.... by the dipstick tube

Found the Pulse line!
Not on the place as in the picture but a little higher in the middle under the Carb.

It is not connected and as the engine is starting it is working

Thanks and greetings,

Erik.
