A lot of times the parts aren't machined correctly to make that perfect fit.
Some pilot will take the red sealant...NAPA, and attempt to seal around the carb.
I would try this sealant where you saw the clear stuff.. Tighten all screws..(NOT OVERTIGHTEN)(silicone)....I am not familure with this make of engine, as I fly other brands...
If I am not mistaken...Tower sells this brand...If not ask your local hobby shop )LHS and thet can help....do you have an instructor??? I strongly suggest you get one...It will save you a lot of heartache.

I use the Fox miracle plug...about 3 bucks...If you go to an event..(where Fox puts on a show)..you can buy them for 2 bucks each.
Remove your plug, and attach your glow...see if it is glowing bright..This is not a guarantee but you can see if you are getting fire....Some glow but aren't good...If it is dead...It will not glow at all.
I would replace the glow plug with a new one anyway, and seal where it was..use good fuel...NOT OLD FUEL! Make sure you glow starter is charged,
open 2 1/2 turns on the needle valve and start it! Hold you finger over the muffler (WITHOUT GLOW STARTER) and rotate the prop until you see fuel come up into the line. Attach glow and start.
Adjust accordingly...cw for leaner...ccw for richer...
Good Luck,
