Honda GX390

I think I've been engaging in bellendery and confused the two measurements on the feeler gauges.

So with a cool head I reset the valves cold then ran it up and reset them warm.

It now runs better but lots of resistance on starting, to the point of snatching the starter cord.

Tick over still a little high with it coughing at times.

tbh, I’m impressed at you changing the head gasket.

A few years ago you couldn’t change the oil filter on your chipper.

I changed the H gasket on my grinder recently, admittedly with the guidance of my brother on FaceTime periodically, it’s not that easy for guys like us.
Chapeau Stu!

I struggle to put my shoes on some days Mick 😀

the Honda information sheet I linked to doesn't say about reseting the gaps when warm, it just says

If adjustment is necessary, proceed as follows: a. Hold the rocker arm pivot and loosen the rocker arm pivot lock nut. b. Turn the rocker arm pivot to obtain the specified clearance. c. Retighten the rocker arm pivot lock nut while holding the rocker arm pivot. TORQUE: 10 N·m (1.0 kgf·m, 7 lbt·ft) d. Recheck valve clearance after tightening the rocker arm pivot lock nut.

Not sure if this reseting on a warm engine is the right thing to do?

Anyway, at least it's running.

Cheers Mick,

Was that the Quad chip back in 2012?

 The oil filter in a nightmare place above the slewring.

It required a home-made 'MouseTrap game' style chute for the oil made from water bottles.

I failed every time to cleanly change the oil.

The first oil change was done by the dealer who too failed and charged us €80 for steam cleaning on top.

Last week I changed the Iveco radiator!

I bought one on offer from AutoDoc for a mere €80 !

Took me under 3 hours not rushing.

I cheated a little and didn't reinstall the plastic McGuff surrounding the radiator.

Saved myself between €600/€900 plus vat

Cheapest quote was a mobile mechanic, highest a verbal quote from Iveco main dealer.

I used your guide thanks but the resetting warm was advice I read elsewhere.

Anyway, I'm going to remeasure the gaps once I've received the fresh rocker cover rubber seal which leaks a little.

   Thanks for posting that guide.
