HI there, I am new to Nitro /gas motors and have my first question, I am trying to start my motor but there is no pressure in the gas tank to push the fuel into the motor , what would be the cause of this, I already looked at the pressure nipple and it is clear of debris
thank you

You must have a clog somewhere in the line for it not to get pressure. I've found blocked fittings before in my K&B OB's. It drove me nuts trying to find the problem.

I got a 3.5 outboard tunnel and when I try to start its a pain when I get it warmed up it works fine I have to blow in the pressure line too get it fired after to get gas too the carb after that it runs good

I have always had good luck priming OBs by moving the throttle from WOT to full closed and watching the fuel line while the starter is buzzing. Closing the throttle is just like putting your finger over the carb or exhaust, but is easier to do when you have a radio in your hand.
