Crafstman chainsaw at full power when started

The link shows components of the saw.

Three fuel lines...

1. Fuel tank dip tube (fuel filter) to siphon side of primer bulb


2. Primer output to carb in.


3. Fuel return to tank.


Likely you have reversed the primed bulb lines.
Disconnect the line from the primer bulb to the carb. If you have the correct connection from the tank to the primer bulb, fuel will spurt out the bulb as you press the bulb

If no fuel, move the line at the primer bulb to the other primer connection. Press primer bulb a few times and fuel should spurt out bulb.

If still no fuel then a problem with the fuel tank dip tube or plugged filter

fuel return line back to the tank
if it has a primer bulb , one line will go there , one for the suction line for the diaphragm and the return line for excess fuel back to the tank to prevent flooding

During maintenance or replacement of the hoses it is easy to swap the hose connections at the primer. The center connection from the primer connects to the return hose that connects into the tank. The feed from the carburetor connects to the side connection of the primer bulb.

If the tank is full it can fool you as you prime because the return line to the tank that is full can be a pickup of unfiltered fuel and bring debris and air into the carburetor.

The primer pulls the fuel through the carburetor purging the air out. Usually seven strokes are recommended. You can observe through the primer bulb the air as it is purged resulting in no air left in the primer or carburetor..

try switching the tubes on the back of the primer bulb

PRAY! NEVER BORROW a father in laws equipment!!!! Let it sit for a short time and cool down and then see if it will start. I would also check the air filter and make sure that it isn't plugged!

The numbers you supply don't cross to an operators manual but that is typical of Homelite/Ryobi. I'm going to make an educated guess that it does not have a primer system. Other Ryobi saws with primer systems include it in the specification. The 3535A does not. Close scrutiny reveals no primer.
IMO fuel primers on chainsaws are one more source of problems. In the USA ethanol additives attack fuel hoses. Without a primer routing is from the fuel tank directly to the carburetor and much simpler to replace. Primers on chainsaws operate differently than 4 cycle engines too. No fuel is injected into the carburetor or engine, its only purpose is to ensure the carburetor is full of fuel,
Typical Fuel hose routing:

• The hose in the tank with the filter on the free end connects directly to the carburetor input connection.
• If the saw is equipped with a primer bulb, an output line from the carburetor connects to the suction side of the primer (once the bulb is collapsed it draws fuel from the tank through the carburetor to refill as it inflates).
• The pressure side of the primer returns displaced fuel to the tank as it is depressed.

From the fuel tank to the carb, from the carb to the primer, from the primer back to the fuel tank. The bulb sucks fuel through the carb excess fuel is returned to the tank. HTH

I have the same problem. I replaced the primer bulb, and the fuel lines. Still no gas to the bulb; (It ran fine before I replaced the primer bulb)

Normally there is a couple of screws beside the primer bulb. Remove screws, remove primer plate. Remove primer and install new one. Some have tabs on each side of the primer. Use needle nose to squeeze these together while you push up to release the bulb.
