"In Layman's Terms"
Note: When removing old non-electric choke assembly take care NOT to over torque the bolt when removing it. The bolt is of substantial size, but the bolt does have a tendency to break off.
Our recommendation, if the bolt does not want to turn (loosen), is to follow these steps:
(1). Soak bolt with Liquid Wrench or an equivalent product
(2). Tap the bolt to setup vibrations and then walk away and let bolt soak for 5 minutes.
(3). Try to loosen bolt.
(4). Try to tighten bolt slightly (this is a trick to try to break a frozen bolt loose).
(5). Try again to loosen the bolt.
If the bolt does NOT come loose, repeat steps 1 through 5 and make sure you give the Liquid Wrench time to penetrate the bolt and bolt hole.
