Hello all, I have a bintelli havoc 49cc scooter. It sat for a bit and the carburetor gummed up. took carb off and cleaned it in process broke the pilot jet ( stupid me ). Bintelli fix is to replace the whole carburetor, Why I don't know (money reason is my thinking). I'm hoping to find just the pilot jet, know size and the carburetors manufacturer . Did order a pilot jet but it is too fat to fit in the hole. The Carburetor is a deni pd18j and the pilot jet size is 35. bike does run with broken pilot jet but very badly. Any help would be great and it dont have to be an exact match just work.

I order one from monster scooter parts which was a cvk style and the jet is too wide to go into the opening.

The wider jet is normally the main, and not the idle. Can you link to the jet that you bought, or even better snap a picture of your bad jet?
Thanks, Matt

I'm interested in knowing how you break a jet and would like to see a picture.

I'm interested in knowing how you break a jet and would like to see a picture. I call your bluff and raise you a flywheel with half an ignition trigger missing, no one beats me on weird crap breaking

I'm interested in knowing how you break a jet and would like to see a picture. I've broken jets. For me it's normally overtighteing. I don't know my own strength. Matt

Here for your viewing pleasure the broken jet. Broke it while trying clean it out. Was told since it has the number 35 stamped on it it was a #35 pilot jet. So far both jets I have ordered have been too fat to fit in the hole. The part after threads heading towards the bottom half is narrower then the new jets. Any help in where to get this would be helpful trying not to have to buy whole new carburetor jet for one broken jet.

Carburetor is a deni pd18j and the pilot jet size is 35. Not presently seeing any pilot jets listed . . but might try contacting ValleyScooteParts.

These are the idle jets I bought www.aliexpress.com/item/Keihin-carburetor-motorcycle-CB400-CG125-250-vice-pilot-jet-spray-PE-CVK-FCR-available-12-injectors/32251289390.htmlI ordered size 30,31,33,35,38,40 twice since they make it mandatory, If they fit you and you are interested and shipping fees are cheap, I can sell you one set of those.

ok the jet on the left is the old jet and the jet on the right is one I have ordered. As you can see the part after the threads is narrower then the new one . Everything else is the same. I know someone out there had to manufactured this jet and I should be able to get one is my thinking but where is the question.

If you can't find anything, anyone with a lathe could take a little off in that area pretty quickly. Might be the kinda job where the machinist just does it for you real quick if you're lucky when you take it in. Just make sure the threads match and all else seems right for certain before you do that.
It could be dangerous, so I'm not recommending this, but it could probably even be turned down by clamping the big end into a drill/drill press and working it down with a file or cutting tool or grinder/rotary tool of some sort in a pinch. You'd have to be careful not to damage the threads.

I had a few 38 pilot jets around. Turned one down about 1/2mm in the lathe. 4.42mm diameter below threads now. If you can't get one done locally and think this would work, lemme know. Measure yours first though, because I could cut more if needed.

here are the measurements from my jet. hope this can help. I cut this one down to 3.75mm there since your pic showed 3.8mm. Looks like it should be pretty close to what you had in most ways. I just realized that we have similar measurements of the end (4.9mm), but my threads are larger and yours are close in size to that. Pretty sure it's the wrong thread. Sorry, I was gonna send it your way but I think it's no use. You'd need more than just that section machined if I'm correct. I think you may have 5mm threads and mine I believe are 6mm (measuring 5.9mm diameter at the threads).
