Carb drain screws are stripped. Any advice

okay so i dumpud a full bottle of seafoam in my tank and my bike wouldnt start.

i am emptying the tank and was going to drain the bowls but i noticed all 4 drain screws are severely stripped.

Any advice to get these out? Thanks

 

You mean the heads are stripped?

I have used the Craftsman Screw Extractor on numerous frozen carb screws. With patience it even worked on the butterfly screws

I did break one of the bits on a head stud because I was in too much of a hurry. Take your time and they work pretty well.

 

don't give up on the screws yet. Try a hand held (not air) impact wrench. with a name like cbccanada you should be close to a princess auto, they sell them there.

 

at the top of "XJ Chat" section in this forum a 5 page thread:

How To Replace Stuck Carb Bowl Drain Screws

...of course, that write-up is for Hitachi carbs. we don't know what you're working on since no other information was provided

 

Don't bother draining your carbs etc, ADD more fuel to the tank.

I don't know how you guys manage to get problems with seafoam, I really don't. I emptied a full bottle of seafoam into just 2 litres of fuel, and there was no problem at all. No hesitation, no smoke what-so-ever, you couldn't tell visually that there was seafoam in there.

I was extremely disappointed that I didn't get any of the advertised after effects - The thick smoke etc.

 

i put 4 oz. in a full tank once. funny thing, it starts slower now, but now i can take the choke off sooner. its so weird.

 

I followed the advice on the forum and removed the bowls from the carbs, screwed them onto a plank of timber and applied heat via a blow torch.

a few minutes and some proding with a slotted srewdriver soon had the little buggers moving.

Tip: don't pick them up of the floor if you drop them..! let them cool first.

 

ok so i drained the tank with the seafoam in it. couldnt drain the bowls but with a fresh tank of gas she reluctantly started. now she idles bad, very choppy and hesitant accelaration. i mean i used seafoam before to fix these sort of issues never to cause it? she wont idle without full choke...

whats my next move?

 

couple other notes. very popcorn sounding exhaust and black smoke

 

one more update...

i got her idling now without the choke.

when accelerating from stop, it pops and hesitates back fires upto 3000 rpm and then pulls fine. you guys think my pilots jets are pooched

hey guys i am going to start a new thread in this
