You may have gunk in the lines or something in the torch.

how is your ventilation? i've been told that an off-color flame could indicate a build up of noxious fumes in your workspace.

using anything but T grade hose is asking for trouble. if this R hose isn't deteriorating as of now, give it time it will.

R is good for acetylene and o2. Propane and some Mapp gas will break it down into a gummy mess over time. and even with O2/acetylene is wears out after just a few years.
The gummy rubber is a paint to clear from your torch.
T is good for all your fuel options and tends to last a lot longer.
climate, UV exposure, and other environmental factors can shorten the life of the line.
I try and do a visual inspection everything I change tanks and replace as needed.
If the local welding supply does not have it in stock ask them to order it in.
