Changed the oil today - HPR30 Penrite. All ok. Went to change filter.It was the tightest filter I have EVER struck, took considerable effort to move. Ryco Z30 looks right on paper, but they are ~10mm too long. Bugger! Already filled with oil too. Put the old one back on. Got a K&N on the way now based on recommendations here. Fired it up, pressure came up fine, then the engine died . Must have been on the edge of reserve. Added more fuel. No start. More tries.....undid union at carb, cranked, got a squirt, reconnected and cleaned up spillage. All good now....it takes a LOT of cranking if the lines are dry. Almost time to lower it and move it into the sunshine...if we get any. Still waiting on Club plates from Vicroads, application has only been in 3 weeks now. FWIW, Club plates are cheap reg for low usage vehicles over 25 years old; only down side is keeping a log of usage, but it saves a bunch of $ - normal full reg is $750/yr here, but club plates for 45 days is $80, or $160 for 90 days. Not as good as the UK arrangement, but better than full cost.
