HELP! Glow plug adapter question...AP Wasp .061

Since Merlin lists the 2019 series in conjunction with a clamp ring, the plugs should fit. However, without an image, an email to Merlin might be in order to ensure that these are plug inserts with a clamp and not an adapter ring with a standard plug.

If you're intend to buy some replacement plugs for your AP Wasp, you should pick up a couple of packs of head gaskets from either COX International, EX Model Engines or Larry Driskill at KittingItTogether. NORVEL replacement plugs (will fit the AP) can also be purchased from NV Engines (bought out NORVEL).

The high performance replacement package (Galbreath head/NELSON plug) is available from KittingItTogether.

But, in all cases, throw away the head shim that ships with the Wasp and use a high quality copper head gasket. The AP gasket is almost impossible to get to seal well.
