I just finished rebuilding my engine and an engine stand to test it on. I was only able to run it for about 30 seconds before I realized the carbs that I thought would work needed to be rebuilt. I have sent those off to Joe Curto. Unfortunately, Joe has a 8 to 10 week backlog. In it’s short run time the only issue besides the carbs seemed to be that all 3 core plugs are weeping. The 2 smaller plugs are 1 5/8" and the large plug is 2". These sizes correspond to several responses on this forum. I ordered new plugs from Ray at RD Enterprises and the set I received were marked 1 41/64 and 2 1/16. I’m trusting that the slightly larger size will help with sealing? Also, per the machine shop that did the work and supplied the plugs I put The Right Stuff on the edge of each plug. It did not seem to do it’s job of sealing the plugs so does anyone have any suggestions for something else? In searching the internet I have found a few ideas:
- Permatex Ultra Black
- The Right Stuff (which did not seem to work for me)
- Permatex Indian Head Gasket Shellac
- JB Weld. This is recommended by John Twist who is the MG equivalent to Miles Wilkins. I’m not sure about using JB Weld as the MG engine uses a domed style core plug as opposed to the cupped style on the Lotus engine.
Any suggestions/hints on installing the plugs so they won’t leak would be appreciated.
Thanks,
Sherman
