Ran it today after a sticky / noisy tappet yesterday, left it on valve spring load all night seems to have squeezed any air out of it.
Am happy with the bottom end so am going to put it in the car , but going to get new cam and followers https://youtu.be/PBDczKBF3LE.
Success! Good to see a running engine Are you also going for a bit more carburation?
Yes it does feel like a mile stone having a running engine.
"carburation"
Yes, but just want evrything inplace first . I can then start playing and making things shiny

nice
easy move to turbo after that
boost reference your gas regulator... its basically a hole and a pipe fitting in the right place
yer LPG has a RON of over 100
good catch on the sticky lifter being linked to a push rod that couldn't turn

No turbo, knocks out too much sound

Still damaged the cam Just looking at a new ones, not sure what to go for yet? VooDoo

Best done with compressed air, the position of the spark plug doesn't help with rope, though it works fine on a big block. A gutted spark plug makes a good adaptor and can double up as a piston stop if you design it to suit.

Rope trick worked perfectly for me on a small block. I always worried that using compressed air could create an issue if the keeper was sticky and the spring compressor opened the valve a little, then all the air would escape. If the piston was at BDC (which seems likely with the compressed air in the cylinder, the valve might drop.
Having said that everyone uses compressed air so I concluded my fears must be unfounded - either the pressure is always enough to overcome any stickiness and/or the pressure isn't enough to send the piston to BDC.
For that reason I'd probably use air next time, and the gutted plug always seemed like an easy way to do that. (I don't think the adaptors are that expensive if you wanted to buy one?)

i always use rope as it's a mechanical stop for the valves. i wouldn't worry about the valve dropping into the bore when using compressed air though, you'd just put each cylinder to tdc in turn so the valve could only drop slightly 'til it touched the piston.
