Leica m4p spool / tulip spring issue

Can I please get some advice / guidance on an issue.  I recently bought an m4p 1 week ago.

The first roll was a brand bought caninister and loaded using the quick loading technique (guide end into tulip, put bottom plate on and good to go).

The second roll was a home bulk load affair.  I think I didnt have a clean cut on the end of the roll, so when I loaded into the tulip, it has 'snagged' on the spring in the centre.

I had to take the roll out as after taking 2 shots I noticed that the film wasnt feeding correctly.

The problem was that as i pulled the film out of the m4p, is stretched the spring.  So now that I am trying to load film, the spring doesnt allow the film to sit in the tulip and load onto the sprockets. (see bottom left hand corner of photo 1.

Photo 2 shows that if a lend the end of the film to sit outisde of the tulip, the film loads, so no faults with the sporkets or loading mechanism

Photos 3 shows a work around where i cut away half the width of the end of the roll, so it feeds into the tulip above the spring, whilst this does work, its not a long term solution.

Does anyone have any ideas how to re-set the spring??  looking down inside the centre coloumn of the tulip, I can see a screw, but Im loathed to start exploring a fix.

I have googled Leica M4p repair manual, but havent found anything.

Any advice would be kindly received.

Without the photos this is a pure guess, but perhaps Photo 3 would explain things. If you cut half the width of the roll so the film feeds above the spring that should be correct. Are you sure you aren't simply cutting the feeder length on the wrong side of the film? When you load the film the film leader should just touch the spring and not compress it much, although if it did compress it a little due to cutting the leader a fraction thicker than normal it shouldn't matter.

 outlined in photo 3, I was looking more for the solution to fix the spring.

Why do you think the spring needs fixing? Maybe post a picture of the spring. I've never tried to load a film that didn't have a trimmed end. The M4-P manual mentions on page 20 that "The film lead must be trimmed like that of all films sold in cartridges".

If the film sits where it does in the last photo I can't see what the problem is and why you would think it isn't a 'long term solution. I can't see where the sprocket holes are engaged in the ratchet mechanism gear teeth in your photos, but when you load the film you should as a last check make sure the gear teeth engage in the sprockets. But I'm still baffled how the spring has been damaged and why the last photo is somehow wrong?

Thanks Thomas for coming back to me and also sharing the manual.  That has in fact worked.  I was concerned as the original bulk loaded film loaded correctly without the curved cut edge.  

 

Thanks for sharing
