When lt125 sits a week it will not start. The primer pumps up and stays out.
But it don't get enough of gas in engine to start. If I get some gas in plug hole it starts
and runs good. How can I get Gas in engine better? Thank You.

 

If it's a bulb style primer it may have a pin hole in it or the hose causing air to leak in which will cancel out the vacuum that normally draws up the fuel.

 

I put a new primer on the carb.
I cleaned the carb and the float is set.
Question.......if throdle is held open while
engine is cranked will there be more gas
to the engine? Thank You.

 

no, more air
