hey, i got a new carb for my ryobi (ditched the single needle one) and now it wont draw fuel when i try to prime the engine (i put my finger over the carb and flip the prop). i think ive got the fuel line hooked up on the right nipple, but htis carb is a tad bit different than my other one. it has a small brass nipple beside the needles, and a large plastic one on the other side of the carb. i have tried both, and still havent got this to work. the carb has just been rebuilt ( the guy i bought it from rebuilt it right in front of me). could there be a leak at the manifold? or is there another problem?

Andrew,
Plug the nipple next to the needles. It is for the primer bulb.

ok, i'll try that.

If that don't fix it--get a rebuild kit for your carb and replace the diaphrams.

the shop that i bought the carb from rebuilt it right in front of me.....i looked at it more closely today and discovered that the manifold gasket was damaged. i got a new one, and now it works like a charm!
