I bought a few Norvel .074 helicopter engines last year that didn't come with glow plug inserts.
Found some inserts on th'bay today. One seller has 5 for $22+ shipping. The other one is selling 2 for $25.00.
Part number is 110158. Don't know how long the listings will last

Better than that is the Norvel turbo plug adapter!
I did the standard plug insert too not near the power out compared to the turbo plug.
