The PA Merlin .75 and the RO-JETT .76

I have read from other treads that these fit a ST .60 mounting which in mm is 20/44
However ; what about tank size ?
I have currently 6 OZ (one 6.5 oz) tanks in my planes.
Is that sufficient for a full pattern run ?

Not really you will need to plan on an 8 ounce tank, athough some are doing the pattern on a little less. I need 7 ounces min.

The PA 75 is the same bolt pattern as the ST 60. I do not know about the Jett

The RO-Jett 76 has the same mounting dimensions as Richard's other engines (51, 61, and 65). It is not the same as the ST 60.

I have flown the pattern with a six ounce tank and the RJ 76, but I don't recommend it. You have to choke the engine down too much.

Winfred is flying a RO Jett 90 with a great big grin of late....
I have no idea what sized tank he is using...
