could have a flooded crank case. You could try and split the bottom of it and see if fuel comes out. there should be nothing but air in there. or just pull it into a wheelie position with the carb off and see if fuel comes out. It's getting fuel from somewhere!
Try iradium spark plug in the polini kit, I have been running my 70cc polini kit for over a year now, with 2,900 miles on it and still going strong. My carb' squirts a bit of fuel into my airbox. My mechanic says it's normal and all carburettor bikes and scooters do it. It will do 57 on my inaccurate speedometer, 51 mph on gps, down hill. On a flat about 45 mph on gps, 51 mph on speedo'. That's with standard variator transmission and 8 gram rollers. I am getting a racing variator clutch bell and belt, with 8 gram rollers fitted. So I might see more speed out of it in the future. They are reliable, Italian engines, Polini are and I have put Aprilia stickers on my Kymco because it's engine is Italian. Sounds like you might have an air leak in the reed valve, with the revs hanging like that or the main jet is too lean, maybe not enough oil in the mixture too. I run 32 to 1 premix, So maybe try that first and then go and have a play about with the main jet sizes. Hope she keeps running well for you. Sorry for the long comment.
Lots of great knowledge right here in this comments section! I appreciate each person who takes the time HarryWilson822! I've not gotten my speedo hooked up on my super 8 2t 70cc as it come with wrong style cable.
To be honest I've never seen that before. It was lookin better towards the end of the video. Have you replaced the reed valve? There's a lot of things that could cause that.
@thelagmeister hey I just realized since my bike has actual parts that are correct without a port like before on the intake base I just remembered Ryan had me take the retainer off the main jet. Now I'm thinking that could be The Culprit Issue Go to 47sec mark into video to see the piece I'm talking about to let me know what you think brother I'd appreciate it!
@@ORIGINALCONCEPTGARAGE The little black dish thing. I'm not going to lie I've never seen one of those in a carb but I have to assume It serves a purpose. I would definitely put it back in and see what happens. If the bike never did this before I would start working backwards. I would throw the old intake back on. Put the retainer back in, Make sure the float is moving freely. From what I read they said the best air screw setting was 1-1.5 turns out from closed. With the carb upside down the float should sit 16mm above the base of the carb give or take a litlle. When was the last time you changed the spark plug? Two strokes love spark plugs. For the most part it sounds pretty dang good. I was wondering if you hold the throttle does it keep blowing out?
I'll keep that in mind it still use to not shoot fuel everywhere it does now. I changed the intake that has different ports on it but factory for super 8 plus used different set of reeds as well! I know what atomization means lol. Thinking why is so much fuel shooting everywhere onto the case! Polini CP19 Or Any Cp Carb Comes Pre Tested To Run Perfectly So Float Bowel Doesn't Make Sence Or Considering Since I Have An Untouched Intake Manifold Its Just Different Now!
@@ORIGINALCONCEPTGARAGEthere’s a jet right where the air intake is that sprays little bits of fuel into the air mixture once the air is coming in. You can see it shooting out in the video of that smaller jet near the air intake. You need a filter or pod filter to keep that fuel inside of the carb and also so other particles don’t enter as well. This might help a lot with the issues you’re having with running rich. just my two cents 🤝🏼 hope you can get this issue figured out. Carbs are annoying lol
also, due to my ignorance I wanted to update because I just learned it. Your jet may need to be turned clockwise so that it sprays through the carb, not away from it as well so that all the fuel directs into the carb! hope this helps.
@iamrycefn8130 the only thing is the jet has one opening straight through now the one piece has randomly placed little holes in it hmm.. I wonder if it's where I took out the atomizer piece that sit in the very top or in this case bottom of the main jet which Ryan took out saying those made his bike run worse now I'm thinking could be an issue and I'll put it back to see what happens
Loved your original comment too brother I'm thankful to comments like these because I actually think it could be the reeds as well seriously and will be pulling them out to check them and possibly flip them as they are new carbon ones I installed!

Love your methods lol has to be lubricant inside the case lol but I'll keep your Hawk Tauah Methods in mind though 😉 🤣😂😅

I did replace it not long ago oh hmm... I don't remember it doing this before the new intake was put on with new reeds
@@ORIGINALCONCEPTGARAGE Maybe try a compression test. It could be blow by sending the fuel right back out.
@thelagmeister probably wouldn't hurt honestly

Its called atomization 😂

@iamrycefn8130 thanks for all the informative comments I truly appreciate it
looks like a reed valve problem, they might not be sealing properly
