Tx Bruce. Will check and try ur suggestions. Fuel line is new, but I have reused filter. I used to start it by pulling thru numerous times with just the choke, as primer bulb had dry rotted away and I didn't replace that till this year. It would eventually start that way. Now I gotta be sure it's actually priming; I see bubbles moving back to the tank when I push it in (although doubt this is cause of poor idle).
