Brush and Spring ,,You Tell Me What Happened

[GOPAPA]

My truck (1971 350 )

I was out for a fun drive last week and came home parked the truck in the garage , it ran just fine and has been running great for ever.., it has always started up right off the get go .no sound like rrrrrrrrrrr rrrrrrr rrrrrrr ,,it's been a fast starter since day one..

Anyway I decided to put new plugs in and also a new fuel pump ,,plugs was about time and fuel pump was just for good measure as their life span is ,,you never know..

so ,after the installing of these two things I went to crank it over and "NOTHING" whole bunch of rrrrr rrrrr rrrrr and no quick start ,, I thought ,,darn bad fuel pump,, so checked if there was gas coming thru the line and into the carb ,,yep two good squirts there,,

So next to see if it had fire at the plugs ,, "nope" none there,, next a test to see if the coil was bad,, what i did here was replace it with a brand new one that I have had for a few years that i had for my 72 that I sold , Still no Juice to the plugs.. Just about out of ideas ..and then I decided to look a little deeper and I found that the brush spring was not pushing the brush down deep enough to make contact,,,

I have never had a brush spring get soft before ,,have you? I had to leave the rubber washer out after I stretched the spring out to make it reach ,, put it back together and it cranked right up.

I went and got a new brush and spring and washer and the guy at the parts house told me that in his 8 years he has never sold these parts by them self .only the whole distributor...

So,, any ideas what made the spring get that weak and not reach ?

Sorry next time I will down size
