Hi, how y'all doin?? Im new to the scooter scene so I got a couple questions.....ok, first off, lets realize im in Denver, CO (5200Ft) and my Aero is from Florida.....right now, top speed 41MPH.......ok, having the usual WOT problem everyone has, maybe i can get to 45% b4 it bogs, currently I have no air filter, anything i try bogs it out too much, the auto choke it screwed so its disconnected. Questoin #1: Anybody try these carbs?? www.monsterscooterparts.com/80cc-carburetor-honda-aero-80.html I know they're cheap but they got a manual choke, if they're even decent I want one, plus I gotta get an air filter for it, neone know where to get one?? Next question, I figure it bogs out so bad with any sort of air filter because it's never been rejetted, I know Im supposed to use a #82, if I rejet it, will it finally run with an air filter and, if I DO go with the new card will the same sizse jets fit? or what size jet fot the new one?? Thanks in advance Attachments:

Well first off this carb will not fit on the stock intake as the bolt hole spacing is only 42 mm on the stock intake and this carb has a 49 mm spacing. Yeah they lied. The 49 mm spacing is for the Aero 125. The carb is also 3 mm bigger in the venturi and has a manual choke so you would need to run without plastics or rig something up.
Now, the reason your carb running like it is is because of several reasons. First off is you altitude (you know this but I want to make sure we are on the same page) and you need to jet leaner for 5000 ft. The parts manual says use an 82 (88 is standard) but that change will not cure your problem.
What do you mean by "the auto choke it screwed so its disconnected"? The stock carbs do not have an electric bystarter and disconnecting can cause issues by itself. I created a manual valve system for my Aero 80 and it works super. But the disconnected bystarter could be a major part of your problem. You need to cure this first or fixing the rest will be next to impossible.
No air filter leans the engine out some but you should not be bogging at 45% throttle, maybe 90% and when I up jetted slightly that went away. So for jetting I would recommend an 85 if you reinstall a stock air box. If you go with an aftermarket filter set up the 88 maybe OK once you cure the bystarter issue.

Here's the only way I can get it to idle, or even run decent.....I have to plug the vacum line in to start it, then it dies, then I unplug it and it actually runs pretty good, to about 45% throttle..... I did get it up to 41 today though So, to me, I've bypassed the bystarter.....I think... Attachments:

No you haven't bypassed the bystarter. You created a massive vacuum leak, Your bystarter (auto choke) is bad. One of my Aero 80s also has this affliction. I cured it by removing the crap and adding a manual valve in place of the bystarter. Look here for pics and explanation. www.aeroriders.proboards.com/index.cgi?board=80&action=display&thread=146 I will draw a diagram of what I did and send it to you if you need it. That open vacuum port is causing you all kinds of hell. Either plug it after you start it or add the manual system I have. That open port is leaning out your engine major league and will melt a piston if you continue doing it. It is also why you are only able to use 45% of your throttle.

Leave the hose off the front vertical nipple that goes to the air filter (round thing with 2 nipples out the back and an air horn sticking down. Plug the second nipple on the filter. Off the horizontal nipple on the back of the carb, run a hose to the new manual valve. From the valve run a hose to the big vertical nipple on the top of the intake. Open valve and you are in enrichment (start) mode. When motor loads up and starts to slow down, close valve. Now you are in normal mode and the choke is off. I'll draw a diagram, even though my drawings suck and post it.
