TX200 MKII troubles

[Phil Russell]

Don't panic ..
I have seen this a couple of times and it was because the rifle was 'cocked' but not far enough to activate the sears properly ... sometimes it sounded cocked as it went over the abt. Maybe you did not 'yank' the lever hard enough to get the safety to engage?
I have always thought this a weak part of the engineering as you should not need to yank on the lever.
A solution I found was :
1. had this problem with mine. found it was the piston and spring guide touching removed half a mill from top of guide and it cocks as easy as you like now
So maybe worth checking.

Also note that the end flange on the spring guide needs to be no more than 2.8mm thick or it impedes the piston rod engaging on the sears. Maybe a previous owner has had a fiddle / added extra parts?
Also, assuming you are not getting spring bound.
Good luck
Cheers, Phil

I've had a partially seized safety cause the same issue before.
From all the good suggestions above I'm sure the answer is here somewhere. When they are set up properly there will be no 'yank' required to engage the trigger. It will happen fairly easily and 100% of the time. Keep at it!

Yanking hard on the underlever at the end of the travel will bend the cocking arm bracket where it attaches to the action. Far better to directly resolve the reason for non cocking

Riving the lever back isn't the solution.
Get trigger block out, degrease and oil trigger mech lightly, is the first thing I would do.
Easy to do, costs are limited to degrease agent and some light oil and it is easy and quick to do.
If that doesn't solve it - start investigating further.

+2 almost certain a trigger / safety degrease required

I fully agree that pulling hard on the ul at the end of the stroke should not be necessary but I well remember,a few years ago, that it was accepted as part of the TX200 and advice to do so was freely and sincerely given. I remember questioning this at the time but was informed that 'that is how TX200s are'. I never accepted the advice, especially as I had shot TX200s that did not present the 'pull hard' syndrome. It always struck me as poor engineering ... most likely lax tolerances.
I wonder if recently made models are better.

My last mk3 which was an early HC with the rounded underlever catch was bought secondhand some years ago and I was informed by the seller that it needed a good yank to get the safety to engage. The underlever didnt quite return properly. On inspection the jaws at the end of the underlever were bent due to the ham fisted user.
What it needed was a good de gunk and the trigger setting correctly.

How many times have you heard "they all do that" ?
Air rifles, secondhand cars, etc etc. Usually said when there's an apparent fault that the owner hasn't rectified.

Coil bound may be? Spring might be a coil to long.
