Avanti Autopower

Hi all,

I have been reading the posts for a while now and I was wondering if someone could give me a little advice.

I have an Avanti Autopower, 98% of the time it runs perfect. I commute with it about 20 miles a day and about once a week it seems to hesitate (off and on for the duration of the days trip). The next day it will be fine. The hesitation will occur when I am increasing the throttle. For example: I will be approaching a hill and will increase the throttle and for a second it feels as if it is going to die and then it just takes off like nothing happened.

Most solid ped I have ever ridden. I think I have only had the jeep out twice in the last two months. I am having a blast with this one. Very nice ride.

Thanks for your help.

does this problem only occur when starting to go up hills?

No, when it occurs it seems like it will happen anytime I am increasing the throttle.

if you have two gears, which the avanti autopower does, it might be that the engine switches to the higher gear when you increase the throttle at a certain speed causing a momentary lapse in power.

No, it shifts at about 15-16 mph. I am usually already in second gear (but there is a noticed loss in power during the shift).

i'm no expert, trust me. but I've been working with my roomate on his 2000autopower a little bit. If your bike is pretty new to you, and has under 300 or so miles, it may just need to be broken in. however, what it sounds like to me is that the engine is getting flooded for a moment when you punch it. do you punch it? or slowly increase on the throttle? I'm not sure if this is the case or whether or not flooding a running engine is possible, but that's what seems to be happenning to my buddy's autopower.

maybe someone else out there can enlighten us?

It has about 400 miles on it (650 kil), however I did talk to someone else who said that their float was sticking (on the Avanti Mont), I guess it is possible that I am having an occasional problem similar to that. I never really "punch" it but I never really bothered to take notice. I will next time it happens.

Despite this little glitch I am very happy with the machine. I have never ridden any other moped that just feels that "solid", and the speed is great for a ped. I just want it to be perfect, I guess.

take apart and clean your carburetor w/ carb cleaner. check out you float in the process. also put in an inline fuel filter. i believe the avanti uses the dellorto carburetor? it's probably the easiest carb to work on.

Thats what happens to me on my van ('84 ford econoline with a '95 mustang 5.0L engine) sometimes. If i snap the throttle before i begin to accelerate, it becomes unnoticable.

Snapping the throttle on a moped won't work. Your van has an accelerator pump that uses the movement of the throttle mechanisms to pump gas into the intake and richen the mixture on acceleration...

Wait a minute, that's an idea. The autopower has a few adjustment screws on it, right? If you could just richen the top-end mixture, that just might take care of it. There should be two brass-colored screws facing forward. Mess around with them and see what you can do.

I'm with Miguel, obviously, your problem is transient and could very well be a piece of crud getting in the wrong place. Try the carb clean/filter and let us know wyat happened.

Being that the Avanti has a two jet carb., one for primary and another for secondary, you may just have the throttle right in betweenst where the the secondary is just starting to engage. I've noticed this on my Mont too and just open the throttle a little to get past the dead spot.

Good theory, except if trex is not lying to us, this happens all day long, only one day a week. Maybe this ped has adopted a peculiar religion? :-)

I have had this problem before where slightly richer on the idle mixture screw or raising the needle a notch would fix it.

I have a 2001 Avanti Autopower Moped. My son removed the fuel tank so I could clean the carburetor and jets. Now I have the carburetor back on and do not know which ones line goes from the fuel tank to the carburetor. I am guessing the other one goes to the inlet I see on top of the crankcase just below the carburetor intake as a vacuum line? But I don't know which line goes where. Can you please help me? Maybe a photo? I would greatly appreciate it. If you can send a picture please send it to my cell phone at 508-933-5150 BILL. Thank you so much for any assistance!
