Carb with no impulse line visible

[Ford3000]

I was looking at this video, its one of 4, where the carb is taken
off a Husqvarna 141 cleaned rebuilt and re installed.
I did not see an impulse line anywhere, could there be one that is
fed somehow through the carb body where it meets up with the intake manifold.
I didn't see this, if not then how does this type of carb work.

Yes. It has an impulse pipe that is made into the plastic intake manifold that fits into an impulse grommet that fits into a hole in the cylinder. The Husqvarna 50,51 and 55 are like this as well.

Thanks for explaining, puzzle solved.
Anyone know how the injection on the Makita DCS520i works,
never seen this either.

The Makita's Tillotson carb uses an air injector rather than a typical flap for a choke. That fascinates me also. How it works is rather amazing but it does:

2050s also have the impulse built into the intake block or something along those lines.
