Default what to use to seal a carb and backplate?

what do you guys use to seal your carb and backplate. I have used automotive RTV but I do not like how it sticks to the seals. I have also used synthetic grease, but that does not seem to work the best.

Is there something out there that works, that does not stick to the o-rings, seals?

Thanks

I use Racers choice air-seal. You should be able to get it at a hobby store.

Yes the racers seal will stick to the o-rings, it just depends on how much you apply and how carefully you apply it.

Why would you need to use any sealant ?.
The o-rings that come with it do the job perfectly, if they are not damaged.

if something needs sealing on a motor, go to an autoparts store and buy a tube of Permatex Brand Ultra Copper Gasket Sealer.

GREAT STUFF. use SPARINGLY

There are plenty of good choices when it comes to sealing an engine. The trick is applying the right amount to the right places, of whatever you chose to use. Too much of most anything is (usually) worse than none at all.

Another thing I see a lot of is folks thinking they have an air leak when it's really something else causing the problem.

So we can use any type of sealer

I use Permatex #2 Form-A-Gasket sealant because it remains pliable for when I tear the engine apart later.

Default sealit and ferget it...

most any decent silicone sealant will work, but permatex is the best, i use High Temp RTV gasket maker (26B) it is good stuff stays pliable when dry and peels off easily from rubber seals already there when rebuild time comes... i have even used it to make a suspension part that was made of rubber and broke, it worked rather well...

any anerobic sealer is great, easy cleanup later and comes apart easy. Permatex sells a tube for 7$
