Glow plug position
« on: October 08, 2014, 03:37:29 PM »
Hi Guys,
This has also been posted on HMEM site.
I am currently building the David Parker Vega V twin aero engine (work in progress) and am at the point of machining the cylinder heads. I have trial fitted the glow plug after tapping the thread and hadn't realised just how far back the plug is from the combustion chamber, approx 3mm at a guess. The head is machined according to the plans so I am carrying on regardless but would like any input on just how close the plug end should be to the chamber?
Can anyone advise?
Thanks in advance.
Rich
