I think the people advertising the M-20 as able to run the Cuda or the Wildcat, should edit the decription and explain it's not going to run it full power. Truth in advertising is key for a happy customer. I don't know why they say what they do... if you look at the specs for the Cuda, it obviously needs two M-20's to run full tilt... but people shouldn't have to spec out a torch and match it up, if the description says something will work.
Call Carlisle and ask for Chris. There is no reason you shouldn't be able to get an answer from them on this... Chris has always been really helpful to me. Explain that you've called several times and you really need an answer.
