trout104 Posted April 12, 2018 Report Share Posted April 12, 2018 Been trying to figure out what the numbers are on the cover of the choke.. L20B. Engine size.. AY 1 M7 13 2KT 60-1. I happen to find a NOS one still in the box, the one I have is L20B AY-1 D5-18 2KT60-1 But being 40+ it is worn out, looking forward to seeing how the wagon runs now. Gotta wait for about 2 ft of snow to melt first.lol...thanx Quote Link to comment
datzenmike Posted April 13, 2018 Report Share Posted April 13, 2018 There are probably dozens of different L20B choke heaters for every combination of emissions settings, years, ignition advance, high altitude, Cal/Fed on an on..... It has to allow the engine to warm up and drive properly but shut off as soon as possible to reduce HC emissions. I wouldn't worry about it as long as it's for an L20B. Quote Link to comment
