Conti Club overhaul

1) The thread sealant recommended by Conti is Loctite 577. Yellow, thick, seals loose threads well even if not cinched down. This allows for elbow orientation. Dries firm but not so hard that removal is difficult. Flare and knuckle fittings do not get sealant but only need to be directed at the exac...

Conti Club overhaul

The noise is the pump straining for water. The Flojet may not be able to keep up with the on-board pump or the 1/4 OD tubing may not be large enough. Try 1/4 ID. FYI this machine can be made to fill the boiler with the on-board pump providing the water pressure. In other words, it can pump

Mazzer Super Jolly Won't Start

It could be that the flap switch is stuck in the up / off position. See if the flap moves freely up and down or bypass the flap switch with a short piece of wire at the contactor where the flap switch connects... to test that theory. Otherwise it is very likely the contactor itself if you can manually
