2 days ago i noticed that when cocking my HW50s, that at a certain point there is a noticeable metal scrape during the action.
I took the stock off to have a look but you cant see much more than just the leaver moving up and down a slot. - it was clear that it wasn't the piston itself as the scrape was still present even with the spring cocked back while moving the action.
I walked over to the garage to look for any oily substance to help lube the gun a bit. - I found 2 stroke oil i use in my KTM 300... I put a few drops in the slide and closed the gun up again
After a few pellets I could feel the scraping subside slightly and thought it would eventually just work its way out with the lube having definitely helped. - I did notice a slight amount of smoke after each pellet but this did not worry me as I knew it was probably residual oil and the gun still sounded exactly the same.
Today i got a urge and placed my target out, loaded the HW50s and BOOM!! - Guys it sounds like a firearm! I took one more shot to confirm and BOOM!! YES definitely this thing is Klapping like a 22 rim-fire with significantly more smoke than 2 days ago. - My ears were hurting it was so loud
So my questions:
1. I thought the piston was sealed and it drew its air thought the front when you cock the gun? - how did the oil get in there?
2. How do I fix this? - I will not shoot the poor weihrauch like this.
3. In future, if ever I want to lube anything on this rifle, what should I use instead? - 2 stroke oil is obviously not advised
Sorry for the long post.
Thanks Guys and Happy new Year!
