[QUOTE="Monkeypants, post: 2561, member: 2708"] The threads were worn out on one of my exhaust ports too so I used a co**** thread tap of the correct number tpi to cut threads further into the aluminium. One of my National Co**** Taps (can't remember if it was 3/8" or 1/2) did the trick. I mounted a wooden handle on the tap and then very carefully scraped around the port using the remains of the old threads as a guide. Since it is only soft aluminium, it's rather easy to cut oversize threads this way, as long as you have a sharp tap. After about twenty minutes of this I had nice new threads in the port. It worked so well that I did the same procedure to the other exhaust port, however it only required a few minutes of scraping to clean the threads up. The main problem with the second port was carbon buildup in the threads, so the tap easily removed that. Fortunately I was able to procure a set of Bronze Maughan Exhaust nuts which were a bit oversize. These were some which Tony Cording had purchased years ago but was unable to fit into his Prince exhaust ports. After a bit more scraping to get the individual fits , the nuts threaded quite beautifully into the slightly oversized ports. [/QUOTE]
