Morning gents
I’m going to strip the engine down and have a look at what has happened; in the meantime I thought I’d detail what happened here in case anyone has an idea what might have occurred.
I was running the machine when it cut out. Trying to restart I found no resistance when pulling the starter. I assumed the spark plug had worked loose but unfortunately not.
I took the spark plug and exhaust off to try to have a look at the P&C but couldn’t see a great deal so just chucked the engine back on the truck and got the spare out.
Half an hour later at lunch I had another look and it started...but stopped again with no resistance on the starter. It feels like zero compression.
When hand turning it feels like the piston is smooth and that it is running the cylinder nice and cleanly...which makes me think it is a problem with a valve.
On the way home I dropped the engine into a local Stihl dealer, a very good one, and they just called me back. They haven’t disassembled it fully but they have checked the valve clearances etc and can confirm no compression; they suggest either an engine rebuild at circa £500 or buy a new one.
Luckily I have a spare and I’m willing to have a look at the broken one myself and I have you guys to quiz. I’ll update the thread with pics when I get into it...sods law I’ve just started an 038S rebuild.
Thanks
Karl
