CV carb, jetting, mix, float, gas leaking?

[Curtis629]

05 Electra Glide Standard, CV40 carb, Dynojet kit, SE stage 1 filter kit, Wild Pigs muffler, 24K mi. Got the bike a few weeks ago and noticed an exhaust/gas smell while riding more noticeable at decleration. After reading the forum and others I thought it might have something to do with the Dynojet kit the previous owner had put in the bike.

The Start: bike ran ok, pulled good to around 4500 rpm, started good, idled fine, only issue the exhaust/gas smell while riding. Carb had dyno jet emulsion tube, 170 main jet, 48 slow jet, slide was drilled, dynojet shorter spring, adjustable needle on the 4th grove from the bottom up, and 2-1/2 turns on the mix screw.

The Change: bought these from the dealer on Sat morning and put in a new Slide, Spring, Emulsion tube, 190 main jet, 45 slow jet, stock needle. Hard to start, idle rough, coughs bad, test ride, pull in 1st and 2nd to about 2500 rpm then slugs off to nothing. Surges, backfires, at idle it dies, hard to restart. Got it back home, noticed raw gas dripping from the air cleaner after I shut it off. Took the filter off and it looks like gas is coming up out of the main jet holder in the center of the throat (the part the needle slides into), looks like gas is overflowing, when I push the slide up with my finger I can see fuel easily coming out and into the carb.

Then, I tried adjusting the idle screw between 2.5 turns and 3.5 turns, shimming the needle with 1 and then 2 washers. Same results, popping, coughing, motor wont even rev over 2800 rpm. Adjustmend were made to the mix while the bike was idleing on the kick stand, when I stood the bike upright the idle got much worse and killed the motor, then it was hard to start again with fuel seeping out the bottom of the filter again.

Then I figured I've done something wrong wth all the new parts I put it to "improve what was already working" ha! So, I put the dynojet kit parts all back in, reset the mix to 2.5 turns out. When I first started it, I thought it was back to baseline, then it acted the same as if the stock parts were still in the carb, popping, coughing, maybe even worse, Each time I rode it up and down my street and it won't even rev while riding over 2800 rpm now. I got back to my garage, pulled the air filter and gas is seeping past the needle jet holder in the carb same as before and when I push up on the slide it looks like gas is coming out of the jet holder (overlowing). It does this till the line is emptied from the tank (its a vac petcock still).

What could it be? I never took out the main jet holder so I don't believe it's upside down. Could I have bumped the float when I had it apart? The float moves up and down when I turn the carb upside down I could see it move. It looks and feels like a good tight seal on the intake and once it's started I didn't leave the choke on. I thought about taking it to a dealer to get it dynoed after the stock parts were in to dial it in if necessary but now it's not even rideable to a shop with the stock parts or after putting the dynojet kit back in. I've screwed something up, please help.

Since there are no replies, I thought I would try to help you out. I am by no means an expert, but it sounds like your float needs to be adjusted, or there may be some debris in the float bowl that is keeping the float from seating and shutting off the gas flow. The EPA forced the overflow tube to be removed from CV carbs in the mid 90's (if I remember correctly) so the excess fuel cannot just flow out of a drain hose on the bottom of the carburetor (hence the leaking out of the needle jet holder). That's where I would start, at least.

The float valve had gone bad and had to be replaced. The float reset and all is good now. All in with a sportster needle too. Runs great, waiting to see how it does with the gas consumption. haha
thanks to all
