B&S Model B compression release

#1 08-09-2004, 04:07 PM

Hello. I have a 1942 Briggs & Stratton Model B and it doesn't have the compression release on it. I was wondering if this was a later addition or were they on all engines. THANKS

My 1939 crankstart B has one.

I have 2 model B's and neither has a compression release. I also have 4 ZZ's and none of them have compression releases. I'm thinking the release was a rather rare option.

Compression release was only for the engines with hand crank starter.

I have a Briggs "Z" or "ZZ" on a trash pump and a model "B" both with compresion release. It probably depended on what the engine was used on as to wether or not it had the release.

only crank starts have the release arm. I have "twin" model B's both built in 42 and one is crank start the other rope only the crank has the lever

I think our '46 B has the compression release and it is a hand crank.
