Small Engines (Lawn Mowers, etc.): GX160 wont start, hp honda, feeler gauge


Question
QUESTION: I have a 5.5 hp honda GX160 motor and it wont start. It ran fine and one day it started messing up so i took the carburator apart to clean it and i took the main jet out to clean it and i lost it. I ordered a new jet and put it in and while it was sittin i made sure it had clean gas in it and changed the oil. I got the new(stock) jet in it and everything together and it wont start. It has awesome fire but it seems like i will pull and pull and then take the spark plug out but it is still dry. I sprayed it down with carb cleaner but it still didnt help so i dont know what to do from here im tired of struggling with it, do i need a new carburator?

ANSWER: If you spray starting fluid directly into the carb throat, will the engine try to start?

Let me know.

QUESTION: I sprayed some in there and it didnt do anything but shoot a little flame out of the pipe(straight pipe) ... it didnt like fire up or anything but it seem like it burnt it

ANSWER: Remove the valve cover and make sure both valves are moving.  When you pull the string the vavles should move quickly.  Sticky valves will generally close slower as the spring tries to close them.  Are you familar with checking valve clearance?

Let me know.

QUESTION: Yeah their both moving but im not sure exactly how fast they are sapose to move. Im not familiar with the clearance or anything but thats what i thought the problem might be and i wanted to take the head off and look at them but didnt wanna mess anything up anymore than it already is

Answer
Are you familer with top-dead-center?  Set the piston at TDC, I insert a WD-40 straw or similar soft flexible tube in through the spark plug hole to feel when the piston is at the top of the cylinder.  At TDC, check the valve clearance with a feeler gauge.  You should have .004 inches of clearane.

Let me know what the valve clearances measure.
