I have an st60 converted from RC with what looks like a delrin venturi. The size is approx 5/32 in.
The model is a saturna v60 with no muffler lugs.
Is the size of the venturi about right? What fuel do you recommend for this engine?
Thanks for any info you can provide about the engine.
Regards,

If you can find one a Bolly 13 x 6 is the best we ever found, a Bolly 12.5 x 5 2 blade and Bolly 12 x 6n 3 blade are excellent too
The ST 60 use a .181 - .195 venturie hole , or a .280 - .310 in a resrtictor, depending on the head type
use 23% oil 1/2 castor fuel 10 nitro
13 x 6 launch about 8600 rpms
Most of the early ST 60s were chromed, they were also very thin sleeves
the ST 60s mostly all had "Chromed" molded into the case, Most all of the later runs were not chromed, even though they said they were
I never saw a chromed crank, and I setup near 700 of these
