Hello all.
I´ve bought recently two Super Tigre 46 (mi first Tigres, by the way) who were unused from the eighties. Completely dismantled, bearings changed, rings known to be good, and test run showed a very powerfool 4 stroking (good sound for "release" at 9200 rpm with a Top Flite Power Point 11x6, on 25% (50-50) oil and 5% nitro.
All seems good, BUT, searching in the web for information I think stock venturies size was about 4 mm (.157 more or less) while mines both have .195 (5 mm.)
Is this venturi usable, or will have suction problems?
Has some of you made tests with ST 46 venturies?
As allways, thaks for your help and time.
Regards.
Manuel.

Hello Manuel
The ST 46 came with a .157 venturie size, this is a little on the small size, what works best is one about .175. The .195 ones you have are a little large, and you may get the motor to break too hard with that large of a venturie. A .195 is much larger than a .300 restrictor
