Default LEAKING JPX JAMMIN / PICCO CARB

Does anyone know how to seal the picco carb? This carb has leaks all around. My original one was leaking from the lsn needle and from around the boot. I tried to fix it but to no avail so I got another jpx-picco carb (used) from my friend who has one sitting around from an old motor. And that one too has leaks.

So my question is that does anyone know how to completely seal the carb or if not then does anyone know which non picco carb is a direct fit to replace this strainer for a carb completely?

I had some leaking problems around my carb base, boot and lsn. I pulled the boot off the carb put a little air seal in the groove and pushed it back on. Same with the base of the carb... a little above the o ring and pressed it back in and tightened it. afterwords I ran a bead around the base of the carb, and the tightening screw both sides and also the boot. For the lsn i replaces the o ring. Also a good idea to air seal the fuel nipple and back plate... Hope this helps...

U can also Jb weld any noticeable cracks or splits just make sure not to get any inside the carb and let it dry good before you use it..You should also take it off your motor before doing so

ahh the good old picco carbs... i replaced mine with a nova carb that was turned down to fit the block....ill Never Ever EVER run a stock Picco/Jammin carb...they Suck beyond belief...the seam between the composite and alum also needs to be sealed as when the motor heat's up that can become an air leak and cause further issues.

here's a pic of what i had to do to keep the jammin crab working effectively.

Lucky 7 or Air seal WILL not stick to the boot...so dont bother trying to seal with it....1211 or Racer's edge is the only stuff that will make a good bond to the boot.

When I had some picco issues with mine (ended up being exhaust gasket) I mentioned to Ofna about leaky carb and they said they do not leak

now I'm sure occasionally one leaks, but is the problem really as big as its made out to be? You would think if their carbs really had a big problem, they would redesign/change them

well Dj and the other guys have been helpfull to me so I think well of them, but still, for the amount of motors Ofna sells, you would think if there was an issue it would be fixed?? Besides, Picco is Italian, and they build stuff pretty good!
