ST G20 15D
I've had a G20 for a while that had a new piston made for it.
I ran it once, was unimpressed & put it in the "one day" pile.
Well today was the day. I put on a 7X6 and fueled it up. It gave a couple of sharp barks but didn't seem too keen to keep on running.
So I switched up to an 8X6 and we were soon making really encouraging noises.
At last after a few muttered incantations, it gave a good little run, but soon slowed down & stopped.
So I realised it was still too fresh to run that much comp, and for that long. After a couple of short runs on low comp, and allowing a good cool down period. It now starts fairly easily, but still hasn't built up a good piston seal. So it looks like its going to need a fair bit of running before it can get into the air.
But I'm a lot happier knowing it's a going concern
