Anyone know how to remedy this or should I just ignore it and run it?

It's the stock mach 26SS engine in my Aftershock. Not a great high dollar engine, but one would think it would still function. I broke it in without doing anything to it. Then I noticed it was leaking all around the base of the backplate, so I cleaned it and siliconed it. No more leaking there. Then I noticed it leaking around the carb neck, again, cleaned and siliconed.

Now, it's leaking around the throttle barrel bad enough to get out past the protective boot and make a mess out of the LSN and side of the engine. I'd understand a drop or two, but this is nuts. Every time I run it, I have to clean up a mess. Besides, if it's leaking that bad, it has to be affecting the tune. It does like to run hot (250-265 avg). If I tune it richer, it runs like a dog and loads up then dies in a matter of a few seconds. If I go any leaner, it looses power and temps will hit 300F, did that once.

Any suggestions? Or just deal with the mess until the engine dies?

I have an axial 28 that is hardly broken in sitting and waiting... I'm just afraid it will be too much for the AS axles and I don't want to deal with that. At some point, the axial is going in.

Anyone know if a carb that will fit the 26SS? Again, I know it's pretty much a throw away engine, but if I can find something better on eBay, it might be worth a little bit of $ to fix it.

Thanks.
 
I've heard of people putting a dab or grease on the carb slide. also putting it on the rubber o-rings on the needles to help them seal and not hang or bind, just make sure you use stuff that wont eat up the rubber.
 
Your best bet would be to find out the diameter of the stock carb, and try different manufacturers...
