eddeere Posted November 23, 2014 Share Posted November 23, 2014 The air cleaner on my B 61 has a 3/8 '' pipe plug with a hole in it on top . It had a cotter pin in the hole. What is the purpose.

Mike Posted November 23, 2014 Share Posted November 23, 2014 I'll go for the booby prize and say the cotter pin was to keep the nut from becoming lost. Many of those air cleaners had a cup mounted for ether to be used to help start those ole B Models during the winter months.Oh! Make sure if I win the booby that it is examined by a pro before shipping it to me.Thxmike Quote Link to comment https://www.bigmacktrucks.com/topic/37836-air-cleaner-question/#findComment-267879 Share on other sites More sharing options...
fifth wheel Posted November 23, 2014 Share Posted November 23, 2014 Use a nail or something handy to remove the plug to give a sniff, I use brass plugs finger tight or an oil cup.

Superdog Posted November 23, 2014 Share Posted November 23, 2014 I have a couple that have a ether pill canister in place of that plug.The top comes off,you dropped in a foil pack "pill" and pushed the cap back on,it would pierce the foil pack and release the ether.
