You could tie a piece of string to it and to a door handle and slam the door................................

Nah just joking.

Whack it in the oven at 400, use oven mits, yank it out and twist away at it till it comes loose. Make sure the cinch bolt is not digging in to the carb sleeve.

belive it or not,I just tested all of them(2 3 ports and a 5 port)...


Each one has a seized carb...as soon as yoiu twist it,it locks up...
'

all the cinch bolts are loose in their settings..

I tried heating the motors with a heat gun...how would the oven be differnt?...


And wouldn't that melt the orings in the carb?..

It has happened to a number of my RB motors too.

The oven gets it hella hot, probably more than the heat gun. I disassembled my carb as much as possible first. But yes the carb o rings in the case itself got hard and ruined. I had to replace them.

has it happened to anybody you know with a Nova style engine also?.....


I wonder what causes it..maybe some anti sieze compound would help before we start them..

Man that badboy is sure stuck in there. That trick worked for me.

You might have to go for more violent (and damaging) methods of extraction.

It happened to my friends RB the other day. I took it home, put it on the oven for 25 minutes at 350dgs, and out it came. I just had to put a little musle into it, but not much.

Thanks,

Steven Muller

I forgot to say, one thing I do when I take my carbs off the block is I sand or file the part that goes into the block. The capturing pin leaves marks on it, and IMO thats why it stucks in there

Thanks,

Yep if you cinch down too hard on the retaining bolt it scores the case and causes a "ridge" in the metal of the carb tongue. This makes them hard to get out. Get the 6mm HUDY driver and you can feel when the carb is tight but not too tight.

I'll leave it in a bit longer,but this thing is stuck...I never overtighten the nut either..


Just one more reason I'm finally going to get rid of RB;s forever and run OS motors......
