Got a BMS Heritage 150 with 1 mile on it. Got gas in the canister and took it off. Fuel filter put on the hose for the gas vent and bolts in the other 2 lines with the clamps that came with them. After I did this it ran fine. Flash forward a week or two and I go out to start it and it sounded like it wanted to start but didn't. After a couple of tries it just turned over without any combustion sounds. Let it set 20 min. or so and tried again. Same thing. Ran the battery down trying off and on. Charged battery over night same thing except I was able to give it a little gas and it revved a bit but then just shut down. This scooter has been in the garage and not driven except up and down the driveway to check it out a few times. After it sits a little while and first try to start it, you can hear gas and air combusting then just the sound of the starter turning the motor. Only hold the starter for a second or two. Prior to this happening it would start almost instantly. Any ideas? Did I mess up what I was suppose to do with the lines on the canister filter? Thanks

Just went out and started messing with the idle and backed it off 4-5 turns and it acted like it wanted to start but wouldn't a few times. backed it off more and still nothing. Went back the other way and still no change.

Brand new and only 1 mile on it, yes. Think it might have to do with removing the EVAP canister. Removed it because it got gas in it some how and it was recommended by Alleyoop on this forum to remove it and put a fuel filter on the gas vent hose, and plug the other 2 lines which made sense. I was informed that after they get gas in them they are bad and can cause problems. Believe it started and ran after I took it off though. Maybe petcock valve? Vacuum leak? Like I said it was starting almost instantly before and the nothing. Talking to my son and he said he did twist the throttle a few times without thinking about it the other day while talking to friends but I don't think that would do it. After it sits for a few minutes and I try to start it, it will sound like it is getting fuel for a second or so then it just cranks.

thats odd
try buying a new EVAP bc it delivers fresh air to the motor and it may not be venting correctly

adjust the valves , and try again .
pull the vac line and while cranking let it suck 1 or 2 ounces of fuel while cranking . it should fire off .
If you don't adjust the valves you may never get it to start . They are known to come out of adjustment from the factory .

[replyingto=tvnacman]tvnacman[/replyingto]How will it suck gas if the vacuum is unhooked? Messed with the idle and it runs for a few seconds sometimes.

Honestly? I would just get a can of Starter Fluid and look to getting it to roll over first and foremost. Just remove the air filter inlet from the carb and spray directly into the carb throat. Not TOO much vause you don't want to burn up your rings or cylinder wall. Just ensure your A/F screw is set 2-2.5 turns out, and adjust your idle accordingly. THEN if it doesn't start, troubleshoot accordingly.
