Yes when I first started having trouble I was running out of fuel and engine would stop but then start again. Pulled the tap apart a couple times. Looked ok but second time I noticed the diaphragm seemed to be sticking. Cleaned and lubricated with petroleum jelly. Hasn’t cut out again but I don’t trust it. Maybe still not letting enough fuel through.
Reco kit for tap, $50. New tap $130. Petcock off trademe $30.
