1992 4.9 timing help please?

hi guys!
i could use some help here please..
have a 1992 f-150 300 inline 6.
i recently installed a used distributor, and decided to put a timing light on it to check.,
it seems to run ok, BUT is VERY hard to start in the COLD mornings, like it doesnt want to fire. otherwise seems to run fairly smooth, but terrible on gas!!
the ONLY way i can get the timing mark to appear in view of the timing plate, is when i put the timing light clip on the #3 wire??
now assuming that the #1 wire, is the wire right up front, i cannot even see the mark on the balancer no matter how much i turn the distributor, when clipped onto this wire.
did i maybe re-install the distributor a tooth -or -so off? and if so, will it still run ok? could this also be part of the gas hog problem?
thanks so much for any help.

If you installed a distributor in it, the timing is definitely off. With the spout in or out, the timing pointer should be visible on the timing cover. Some 300's have two sets of timing marks - thank Ford for that - and you should be using the marks on the driver's side.

Another possibility is this. The balancer is made of two pieces of metal separated by a rubber ring. If the rubber deteriorates, the metal ring slips and the timing marks are all wrong. If you are using the right timing marks then your balancer has probably started to come apart. You can confirm this by moving the engine to TDC on the #1 cylinder and seeing where the timing mark is pointing. It should be close to zero.

You are using the #1 plug wire to time it, right?

when i attach it to the #1, i cannot even see the mark on the balancer, no matter how much i turn the dist. this tells me i maybe off by a tooth or so when i put the dist in??
