ADJUSTMENTS
Chain should, have 7/16" to 3/4" slack, (total up
and down movement), at middle point of lower
span, between crankshaft and eccentric sprockets.
Note: Chain adjustment is correct when punch
mark on handle of feeler wrench has a total move-
ment of 3/32" to 7/32".
Suggestions: To tighten chain, always turn top of eccentric toward you (away from engine). Always tighten
eccentric bolts before checking chain adjustment. If, after adjusting, bolt will not enter hole in eccentric, turn
eccentric back slightly until bolt enters.
Before making initial check of adjustment, turn crankshaft ahead slightly in order to get total slack of chain
between crankshaft and eccentric sprockets. Otherwise the chain may seem to be tight when actually it is not.
