Hi all, I have just changed the valve stem seals on TJB as she seemed to be using oil, I did this job in situ with the aid of a valve spring compressing tool whilst doing it however I noticed petrol seeping from around the inlet pipe at the carb upon investigating the brass pipe pressed into the carb came out in my hands.
Now I dont know if any of you have heard of this happening but I certainly have and the end result is not pretty as you can imagine traveling along at any speed if this comes out even though the engine will stop running the fact that it is turning over will result in petrol being pumped around the engine bay and the chances of it not igniting are pretty slim.
I know of at least 2 RS3100,s that have caught fire through this very problem so please check this little blighter, I am obviously very relieved to have had this happen whilst turning the engine over by hand in the garage it could quite easily been a different story as I was/am hoping to take it to National Day this sunday.
My plan now is to use some sort of adhesive to help secure it in place but I am also going to drill and tap the body of the carb and hold it in place with a small grub screw also using thread lock, I have also spoken to Paul Johnson who tells me that later escort carbs have a threaded brass pipe doing this job but the diameter inside would probably be different and could affect the flow of fuel however Paul is looking into have a threaded item made which would obviously solve the problem.
Regards Len
