If it's weak or not steady flow then it's a fuel delivery problem. Pump on back to tank, as said. You also want to see down carb throat for squirting gas as throttle actuated. (not running/not cranking)

If test fails
1. Pump
2. Clogged/collapsed rubber line
3. Clogged fuel filter
4. Clogged pick up tube at tank
5. Gas cap not venting

Test is good
1. Carb
2. Vac leak
3. Bad gas
4. Coil
5. You don't want to know

Thanks! ...though that last one has me worried.
Sadly it could not have picked a worse time to act up...after 2+ years of running good. To much going on right now. Hope to find the culprit quickly and get moving again.
