Can't get the carburetor off

[Jmart432]

Hi everyone. I'm trying to clean up a gx160 I got for free of a guy down the road before putting it on the kart I'm building. I was having problems with it idling and surging so I bought a new carby for it off ebay and it arrived today but I cannot get the old one off. I've watched a few videos on removing them and I'm sure I've unhooked/unbolted everything but the **** thing won't slide off. I think there must just be a big buildup of rust and gunk on the two bolts it sits on cause when I try to pull it off there is no play at all. I've spent about 2 hours prying at it and spraying it with wd40, carb cleaner, boltoff, etc.
Is there something I'm missing? Or is it just seized up with rust and stuff?

Thanks

Try tapping with a flat screwdriver and a hammer(lightly) on the main carb body... It however should just slide off...
It does look like you/it broke the the insulator plate next to the motor...
Do you have all new gaskets and such? .... you will.

ooh bummer you will need that insulator crack free.
I looks like it should come right off!
Weird

I think I'd take a pair of good vice grips, and grab a hold of the bolts going into the motor. Don't grab the threads though. Grab onto the unthreaded part, and try to back them out, and then see what happens.

This is very good advice! ^^^^

Thanks for the replies. I've done a lot more than tap at it with a screw driver to try and get it out and still nothing (got a dint in the carbys body from a socket extensions I was hitting into it and broken off some of the body where I was prying at it with the claw on a hammer. Not worried though as I've got the new one)

And bbqjoe, do you mean the 2 bolts that the air filter and carby slide onto? Wouldn't I be even worse off if I broke them off? I did try clamping onto them and wiggling them and pulling them but still nothing

If trying to remove the bolts scares you, then the next thing I might do is use a propane torch and heat the daylights out of the carb and see what happens.

kaboom!!!!

WD-40 is useless as is carb cleaner. Get some WD-40 SPECIALIST Penetrating Oil..spray and be patient...it'll come off. May take a couple of days spraying every 4-5 hours...but it'll happen.

Since everything is destroyed anyway...I'd break the all the flanges like the one you broke...so the penetrating oil can work easily.

I wonder if he could somehow hook up a dent puller?
But yes, a few days or a week with some liquid wrench or something should do it.

Oh...he could put a couple of big washers over the center of the carb and hook the front flanges with a gear puller...but he might just pull the studs out of the block...you just can't rush rust removal...and bad things happen when you try to overcome it with brute force.

Thread 2 nuts on the stud then back the first one into the second one tight. Put your wrench, or vise grips on the first one and back the stud out.

Tap the end of the stud and use liquid wrench/pb blaster or whatever kind of penetrating oil you can get your mitts on.

And when the stud snaps off in the block? Then what?

I guess we cant assume everybody knows what it feels like when a stud or bolt is twisting and about ready to snap off.

 

[Bbqjoe]

I still want to go with heating something up. maybe the studs before attempting to back them out.
The suspense is nerve wracking. Just do something!!!

It looks like it's been all boogered up and then coated in silicone to re-seal it.

I'd sacrifice the plastic spacer, it looks pretty rough anyway, pry it off there.

 

[mckutzy]

If you have another new carb then this is a sacrifice......
Make up a vice grip slide hammer....... Grip the bore or the whole thing.... what ever.....
Slammer back... she'll be off for sure.....
Can be used in a pinch, and still retain the use of you vice grip and not sacrifice it in the process.....
A round rod/ready rod with the same thread as the vg, a couple of nuts/washers, and a weight of some sort( anything in this case that'll do, a rock with a hole even).

This is just one of many out there homemade... look them up on the google...

 

[Jrgunn5150]

Someone has definitely already pried that carb off anyway, I can see a big dented portion on the intake side.

 

[Bbqjoe]

I could get that carburetor off!
