Leaf blower will not start

Ryobi leaf blower, ran and then began to run rough and die. When started again you would have to continue to feather the trigger to keep it running. Now it will not start unless you pour gas down the carburetor, priming it will not even cause it to fire. New spark plug cannot adjust mixture screws because of limiter caps this is a Zama carburetor

You can pop those limiter caps off and there will be a small adjusting screw under each one.

Chances are you will not need to adjust the carb screws. Those were already set at the factory the perfect setting for the carb. Adjusting them may not do you any good. However in some cases if the engine is really old than you might have to adjust them because of wear. I would first lean towards checking to see if the fuel is running through the lines into the carb. I want you to do the following before Cheese answers your message.

#1...Check Air hole on Gas Cap for clogging. If so clean out with a needle.
#2...Make sure fuel lines are clean and that fuel is running through them.
#3...Make sure Primmer Balb is working properly
#4...Clean the carberator to the best of your ability.

When a engine is getting spark and the only way the engine starts is buy putting a little gas in the sparkplug, is dew to the fact that the engine is either not getting gas or the carb is clogged up with trash. Complete these steps and let Cheese know what you find, he will also give you information to you.

Hello Irish!

Sounds to me like you either have a cracked/broken fuel line or a carb restriction. You shouldn't have to worry about the adjustments if it was running fine prior to this. These things are bad about cracking fuel lines. Check and let us know what you find!

This unit is just a year old I took the carb off cleaned it and blew it out, with an air compressor, also cleaned the arrestor screen still not go unless you pour gas into the carb. when pressing the primer bulb no gas goes to the carb the end of the primer line that goes into the tank just blows air into the tank and suck no gas into the carb.

You have a fuel problem, did you check the fuel lines? The primer outlet does pump into the tank, not the carb. The primer inlet draws fuel through the carb. The carb is supplide by the fuel supply line directly from the tank. If the carb is stopped up or has bad fuel check valves it will cause this problem with the primer not filling. Also the fuel filter could be stopped up or fuel lines cracked.
