GT33 Compatible Head Gasket 0.4T - OS28304160 by O.S. Engine  [OS28304160]

Performance and Fit for GT33

The O.S. Engine OS28304160 head gasket is an aftermarket replacement intended for use with GT33 series nitro RC engines. Positioned between the cylinder head and crankcase, the 0.4T thickness helps preserve combustion chamber compression and limits leakage during operation. This accessory is for model use only.

Fitment and role: with GT33 compatibility noted in the part name, the gasket contributes to stable compression over multiple runs, supporting consistent throttle response when needle settings and carburetion are correct.

Installation overview: remove the cylinder head and clean mating faces thoroughly before installing the new gasket. Eliminate any remaining gasket material and check surfaces for nicks or distortion. Place the gasket flat, refit the head, and tighten fasteners evenly in a cross pattern, then verify there are no leaks after a test run.

Tuning and maintenance notes: swapping a flattened or damaged gasket can correct compression-related symptoms and stabilize mixture behaviour. Carrying spare gaskets allows rapid changes at the track for tuning experiments or emergency repairs.
