3.5hp Vert shaft, primer button. engine runs only few seconds-no smoke, no rattles, weakens & stops (sometimes with a backfire). Modest compression pre & post. Cleaned tank & carb, was dirty, diaphram looks undamaged-no splits/creases-two flap tab valves(?) 1 flat, 1 angled, main jet filter easily (re)moveable-(poor design?), main jet passes air (can't remove), motor throttles up & down when heavily primed, new 98 RON-plently, oil ok. plug clean seems ok, as it starts well after prime, air filter cleaned. elect ign type. No choke plate in plastic carb. V long re-inflation time for prime button-mounting O ring ok, no real change. ???
