I have started AMCs in 20 degree weather, and yes, takes a few minutes to warm up, but probably because I disconnect chokes on all my cars also, along with no heat riser. Today however didn't hit 100 degrees, woohoo/.....first day THIS MONTH not 100 degrees all time record. On other hand supposed to hit 107-110 Fri/Sat/Sun as dry air filters in behind hurricane Irene, so heats up really quick....on top of our 'worst drought in history' now, the ground has cracks big enough to park Pacers in. But no, don't know what 30 degree below zero is but DO have a pile of NOS AMC & Rambler Engine Block Heaters for no reason. Not for sale just stuff I collect. Thanks for explanation below on what heat riser actually does in climates where you have uh, seasons that change. I always though it was good only to squeak at in opportune times when trying to impress a woman or impress guy next to you in car he thinks is fast, only to rev engine and have rattle & squeak make it sound like AMC needs big wind up key on back turned again. They also are good to paint & give kids if too cheap to buy LEGOs. Look like could be good fishing weights too perhaps! Now send us some rain.
