RTV Silicone can be used to seal the carb body to the crankcase.
Per Trinity: The correct manifold for the Sirio .30 is TRI42000
off road manifold. This manifold will fit the Monster Spyder,
1/8 scale buggies such as the Kyosho MP6/7 series, Ofna, X-ray
and others. It also works with Associated MGT and other vehicles
using a standard style 1/8 scale manifold. (If using the s27
200001 manifold, first oil the outside of the rubber manifold,
coupler before sliding the manifold on). Savage Users: You will
need to grind/file some of the manifold that comes in direct
contact with the Rotostart. the Outside flange that directly
contacts the rotostart needs to have a flat spot in order to fit
properly between the exhaust port and back plate.
Trinity does NOT recommend exceeding 30% nitro content fuel.
NOTE: This is a high performance racing engine and there is no
warranty other than it meets factory specifications at time of
purchase. Due to the use and misuse of this product there can be
no warranty on component life.
