Check your enricher make sure it is seated at the bottom. Buddy of mine had his slightly turned on his Ironhorse which cause popping and hesitating. You really shouldn't have to use the enricher. For me even in very cold weather I don't use it and if your bike is really cold the primary fluid will be so thick you'll be hard pressed to get it fired up anyway.
Not sure but I don't think Curtis does starters anymore, don't quote me though.
Makes ya wonder
Thank you and well said ! I see so many posts on bigger jets and I'm thinking that engine should be flooding out with those size jets lol.
I don't know if it's new or rebuilt. I was just ordering something last night and saw it. I'd think it's a rebuilt.
Yep, there's a lot of factors that can go wrong
I would wonder why then when I had the dealer install my BR pipes, that the pipes came with 31/76 jets to be installed? And it ran great. After I installed the 585 and S&S's dual runner, I could not adjust the carb to stop the popping on both accel and decel, I bumped up to 32/78 and it eliminated all the popping except for the occasional sneezing thru the carb at 50-55mph. According to their (S&S) website on carb setup, to eliminate the sneezing they suggested to bump the inter up, which I did and now I'm running 33/78 without any issues.

With the above stated, all carbs are different due to the tolerance of parts, and if the jets are held to a tolerance of +/-.0005 on the size hole you can have +/-.001 between jets of the same size, hence the air fuel mixture screw to be able to fine tune the carb to the motor.
Bottom line, no 2 are alike
Really depends on what mods have been done. I have 34 inter and 82 main, 630 cam, S&S dual runner, minor head work, and V&H big radius. I do find that adjustments are needed depending on season, and where I am riding, environmental and elevation factors can greatly affect the tune of your carb. If you're intimately familiar with your machine and know how to adjust your carb, I would be inclined to say run whatever damn jets work for you..
So the bike was running ok, but the plugs are black, read this PDF, adjust your carb and run it.
