I agree with Walt. Also check that you turn the main fuel valve open.

The Chinese do not say "just install the engine" Did you follow the manual
de-inhibiting process?
What you describe is probably a non functioning carburettor. Two items
here: 1. Carb is full of inhibiting oil and/or: 2. They sometimes put a
protective "condom" over the ambient pressure sensing tube in the carb
throat.
With item 1. only it will start eventually and run like a shit box. With
item 2 it will never start.
In addition they also usually protect the magneto points with a small piece
of oiled paper or cloth between the points. These have to be removed and
the points thoroughly cleaned of oil.

Subject: Yak-List: Chinese rebuild engine
I just got through replacing my 1400 hour Hosai engine. Old engine ran good
but new engine just sitting in the back of hangar didn't make sense.
Got it installed now for the run in. Chinese Manuel just says install
engine. I assume all stops are correctly set so cables and levers should be
adjusted. On the first start seemed that a mag was off. Will run with
start button and pumping on primer. But, stops when button is released or
prime stops. Any ideas.

Doug is spot on.
We just went through the same problem. Here is what we did;
1. Remove cylinder, ours was #1 so it wasn't terrible difficult. Tedious to get
all the small parts, air start lines, baffles, oil lines etc. out of the way.
2. We sent it to M-14P, Jill reworked exhaust port. She also had to replace a valve
and guide.
3. Reinstall cylinder with new bolts, lock plates, and o-ring. Set all valve clearances,
run and leak check.
Cost: ~$1,400 for parts and repairs @M-14P.
Labor: 4-6 hours if you do it yourself.

We had the same issue on our Yak. Pulled the two cylinders and sent them to Mike
at SuperFinishers in Phoenix. (The airplane is in Phoenix.) I cannot remember
the cost but it was not huge.
Mike, the owner, is a Yak owner.

Fuel pressure? On the YAK the fuel pump can be installed 180 out. Will not run.
Well at least mine did not until I reversed it.

Never mind. Seems the Chinese have different way of pickling there engines. Condoms
on jets. Who woulda thunk it? Oiled gauze between the points is similar to
The YAK.they put something like a silicon grease on theirs. Can misfire like
a son of a gun if you dont get every nanogram off the points.
