I have a weird problem. I put bike together yesterday, and noticed the fuel filter was busted. So for the test start, used what gas was in the carb bowl. It started up. Fast forward today, put new filter on, turned petcock to "run" and no gas came out. Checked to be sure petcock was on and no blockage, still no gas. Checked fuel filter orientation that's good. Took gas line off after the filter and gas came in the tube and poured out. Put that back on and took off gas line at carb and gas came out. So, I think the blockage is at the carb? I don't know what the issue is and I don't want to tear into it with out some advice.
