I have a little 2 hp machine that I'd like some advice on.

It's a 2 cylinder Webster that I bought second hand for about $100.  I've
seen the same unit with up to a 3 hp motor, but mine is currently equipped
with a 1 hp unit that draws about 1800 watts - it blows the 15 amp breaker
when I have it set up to run on 120 VAC (it normally runs on 220 VAC).  It
has a quite small tank as well.

Since it's been 100% reliable, I have no incentive to replace it.  My
questions are:

What would the effect on compressor operation be if I went to a larger
motor.  The 1 hp motor runs the thing ok in warm conditions, but can't start
in cold weather (solution for the last 5 years has been not to work in cold
weather!). Are extra hp just thrown away, like extra octane in gas?  I've
been told that the compressor head is what makes all the difference, but ???

What would the effect be if I hooked up a large tank in parallel (or in
series - which is best?) to the existing small tank?  I suspect that I could
get more CFM over a short period of time, with a longer recovery period,
with the net result the same average CFM but more easily used, if you get my

Your various thoughts are appreciated...
