16 hp tecumseh engine loosing power

[guyfox]

Having trouble with my 16 hp tecumseh engine....It idles fine and I can give it full throttle with no problems in neutral....When I put it in a forward gear and start to run there is no problem...I can run about half throttle all day...The problem is when I open up all the way the engine will suffocate for fuel and shut off....There is no problem starting again and running at half.

I have drained all the old fuel and put in new.....changed all the fuel lines...cleaned the carb (may not be set up right...this is what I am thinking )....any help would be great....Thanks

How does the diaphram in your fuel pump look? I'm guessing it could be worn out. Did you put in a new fuel filter as well? Will it run well under load at full throttle when you put the choke on?

Diaphram looked fine....Did not change fuel filter...and have not tried running with choke open.....

OK, try both of those and let us know what happens and we'll take it from there.

I was having issues with my oh180 and finally ended up with it was the air cleaner so check that out too. Possibly the float is not adjusted right?

Is there a high speed needle adjustment you can open more?
It needs to be set under load so open it 1/4 turn and drive it and see how it reacts.
The choke closes when you pull it on and normally should be open.
