December, 1966
Dealer Letter #154
SUBJECT: DISCONTINUED USE OF CHAMPION UJ-4J SPARK PLUGS
MODELS: 1964 AND 1965 90 H.P. MOTORS
Gentlemen:
Recently you were advised by Service Bulletin SB-#1113, dated November, 1966 to discontinue use of the subject spark plugs in 90 H.P. motors.
Undoubtedly many of you are therefore left with inventory of these spark plugs, for which you have no use. UJ-4J spark plugs purchased in the 1966 fiscal year, which ended September 30, may be returned to your Parts Distributor for credit.
All plugs returned must have been purchased from your Parts Distributor, and will be subject to the normal 10% handling charge.
Please note: Due to the late dating of Service Bulletin SB-1113, an exception is being made on the return only of UJ-4J spark plugs for credit.
Therefore, we are recommending that you return, immediately for credit, your inventory of UJ-4J spark plugs, purchased from your Parts Distributor. Do not return them to Johnson Motors.
Cordially,
JRP:rs
