As chance would have it, I have a newly rebuilt MC 2150 to replace my 2100. Now I just need to figure out how to connect it. Simple, right? Well there's really one port that I think I know what it is, but I want confirmation.
Also, the choke heater tube doesn't seem to line up.
Any thoughts on how to convert this? I'm actually now faced w\ two female sides, so I'm thinking that perhaps even a male / male adapter, but I'm not sure.
Actually, I don't have the other tube from the heater tube that goes to the air cleaner, but am thinking to replace it to make everything "right", if you will.
Your first question I can answer - that's your bowl vent. It should connect to the bowl vent port on your charcoal canister. Your second question I'm at a loss, but I will speculate that you made your purchase from ehrmannmp on eBay and he no longer responds to your emails after you've purchased.
Actually, I purchased it from National Carburetors. Sorry, no prize awarded. I ordered it mistakenly, thinking I had a 2150 to begin with. So, a loss in the core deposit left me with now 2 carbs. Not a loss, really.
So my question is, you confirmed that's a vent. Does that mean I can use that port as the fuel vent return, and ditch my 1:2 fuel filter for a 1:1?
The bowl vent just releases vapours which a good emisison system will suck up.
The fuel filter returns fuel to the tank before it even gets to the carb. This is very useful as it will send vapour, air sucked in through leaky hoses and excess pressure and fuel back to the tank, leaving a low pressure but copious supply of fuel at the carburettor inlet. If you take it out and put in a cheapo filter you may suffer at some point from poor running due to the inlet valve on the carb being overwhelmed or a lot of vapour being pumped into the bowl.
I just picked up the screw on filter for the carb, and will be mounting it tonight. Can I assume that, since I don't have the vapor canister (may install one at a later time), that I can just plug the vent? That's what the guy who rebuilt the carb recommended to do, so dirt and dust doesn't get in there.
As for the choke line, I guess I'm going to have to find a male to male adapter to connect the heater tube to the choke. Don't think I'll try to fire it up before the weekend. I want to make sure everything is correct before hand.
Unless I'm mistaken you don't need the tubing anymore.
Get a breather filter for a Harley and put it on the bowl vent if it will fit under the air cleaner. Or extend it out with a piece of fuel line.
Great idea with the Harley breather. I was trying to think this morning what would fit on there. I may have to find one for another bike though. I don't want to get nailed for a Hundred Dollars for it. In the end, I do intend to add a charcoal canister.
As for the heater tube. You're right that the choke is electric, but it still has a female port where it seems to expect the heater tube. If not, what would I plug into there?
Another question I have. The rebuilt carb came w\ a new base gasket and that soft(ish) spacer thing.
So my question is; I know that a base gasket is supposed to go between the intake and the hard spacer plate, but goes a gasket also go between the spacer pad thing and the carb, or does the carb mount direct to it? My guess would be no gasket, but I know I took one off w\ the last carb... but it just doesn't seem right to me.

Sometimes the manufacture casts the electric choke housing With the exhaust tubing connection but doesn't machine it. If there isn't a hole to pass the exhaust gasses through it just plug the pipe and forget it. Its electric now.........
