SERVICE BULLETIN
TO: BRIGGS & STRATTON AUTHORIZED SERVICE DEALERS
BULLETIN: DSB-1044
DATE: OCTOBER 2015
SUBJECT: RE-START DIFFICULTY AFTER BRIEF OPERATION
MODEL: 400000, 440000, 490000 EQUIPPED WITH READYSTART®
SERIAL NUMBER: 131001xxxxx THROUGH 150923xxxxx
CONDITION:
We have received limited field reports of some subject engines exhibiting difficulty re-starting after short run periods of
approximately 5 minutes. Upon examination, we determined that the gap between the thermostat arm and the choke
rod retainer was out of tolerance. This prevented the choke valve from opening as required for the warm engine
temperature. This condition did not present any starting difficulty on cold or hot engines.
INSPECTION / REPAIR ACTION:
If this condition is encountered, ensure the engine is cold (room temperature) and perform the following procedure:
1. Ensure the governor control (A, Figure 1) is in the idle (clockwise) position.
2. Visually check whether the thermostat arm (B) is touching the choke rod retainer (C). Correct gap is .000-
.050” (.00-1.27 mm).
