LEAK TEST

The following gives verification procedures for liq-
uid cooled engines though it also applies to fan
cooled engines. For FC engines, do not consider
information pertaining to coolant system and pump
shaft oil gear reservoir.
On FC twin-cylinder engines, each cylinder cannot
be verified individually due to leakage from one
cylinder to the other through labyrinth sleeve in
center of crankshaft.

PREPARATION

1. Remove tuned pipe.
2. Install plug over exhaust manifold.
3. Remove carburetors.
4. Insert plugs in intake rubber boots. Tighten with
clamps already there.
5. Using a hose pincher (P/N 295 000 076), block im-
pulse hose.
