my cv-rx is leaking fuel, what gives?

[tmd]

hi all, i came across another problem with my cv-rx. it's leaking fuel, causing the engine to cut off at WOT. i started the car again, and lifted it up from the ground, and went full throttle, it was leaking a little bit, but when i plug my exhaust hole was when gas poring out. here i post a pic on where the leaking occur. what do you think i need to change? do i have to change the whole carb.? thanks for all the help guys

You can try sealing it with PERMATEX ULTRA COPPER Hi-Temp RTV Silicone Gasket Maker. Good luck.

Randy has given you good advice. I use a sensor safe sealant very easy to remove. I think it is permatex as well. Just don't get carried away with it. I use it on the exhaust port, carb base plate and the engine backplate. There is now a lot less mess when I run any of my vehicles. Later.

EDIT: In looking at your picture again it almost looks like you are pointing to the HSN area of the carb. Well if this is the case and you say it cuts out two things are maybe happening. Either the screw has been moved so far out that the needle can no longer stay in the seat. Maybe try screwing theneedle all the way in and back it out three full turns and see what it does at WOT again. Other problem might be that it just has a bad seal on it and you will need to probably get a new needle or new needle O-ring. I would not use any permatex sealant on the HSN at all.
