Where is the choke, new out of the box and can't find choke . Looked at manual and its just not there.

My money is on a partial blockage of the main jet or the passageway to it. You're having to force it to run through the idle jet by fully choking the incoming air. There's not enough gas coming in with the choke open to allow it to run.

I'm thiniking total carb disassembly, carb cleaner and an air compressor combined with a ton of patience will take care of the issue.

Running too lean at full throttle. Yes you need enrich the high speed mixture a little but make sure the blower has warmed up first that if the carburetor is adjustable.

the throttle cable has been adjusted to far foward making choke engagement hard and the govenor speed needs to be adjusted down it set to fast

If it won't start, then pumping the gas and using carb cleaner may make it worse. Carb cleaner is not the same as starting fluid. It will make the engine harder to start. If it's flooded, then pumping the gas will only flood it more. If you need to de-flood, then press the accelerator pedal ALL THE WAY TO THE FLOOR and HOLD it there while cranking. Don't pump it.
Have you looked at the top of the carburetor while someone cranks the engine? Does the choke close when you press the accelerator for the first (and only) time? You state that you replaced the choke; do you mean the electric choke spring? Is it adjusted correctly? You need to know the choke setting for it to work properly.
Then again, it may have nothing to do with the choke. Do you have spark at the plugs? Have you checked the fuel filter?

is the spark plug wire still off from shipping?

DOES ENGINE REV OR JUST TACH READS 7K?
IF JUST TACH READING THERE IS FIX ( RESISTOR)
IF REVS CHECK FLOOR MAT OR SECONDARY ON CARB. HUNG OPEN

I had the same problem. I took it to the dumpster and used my old echo that I purchased in 1986. The Homelite was 2 years old. My sugesstion is to dump it.

Looked through 1979 Motor Manual (similar to Chilton's at that time) and although it doesn't show that exact model all it shows is what I remember, which was a spring going from carb linkage to manifold, which was for tension on throttle return, and gas pedal. The other which would be for choke was simply the thermostatic coil and housing that attached at end of rod that choke was attached to on side of carburetor. When cold, it would retract the coil inside the housing, which in turn would rotate and close choke for cold starts, and as engine warmed up, it would expand and rotate opposite direction and pull choke off. Could this be what your looking for?

needs new choke cable
