i have a victa commando with a powertorque engine which i inherited. a couple of parts needed replacing, which i did, reassembled the whole thing, it starts fine and runs at idle fine but when i push the throttle to full it cuts out, i've pulled it back apart and tried to find the fault but i have no idea! if i pull thye throttle back to idle it continues to run .

any ideas? i'm pulling my hair out!!!!

cheers in advance
martin
