i need help finding parts

[maccrew]

ok update, the arrow was facing proper but i switched back to old filter for time being, i went by a friends dad who makes,assembels and tunes carbs every day at work, he looked at it and said everything seems fine except for how it is not responsive when tuning at time., he tuned it and adjusted my throttle so there was no more dead spot in it. he mentioned because of the oil leak there might be ALOT of excess oil in the exhaust and its clogging up kinda like a catalatic converter on a car. well after leaving his house it was only getting worse on the way home, i seen a guy sitting outside working on a motorcycle so i stopped and asked him about all the issues, told him about everything even the oil leak, i decided with his help and tools to go premix, right there, he helped me drain the fuel and remove the oil tank and hoses and plug the hose going into the carb, the oil pump is still in but the cable to engage it and the hoses are no longer there. we are doing roughly a 45:1 mix, he gave me some ams synthetic 2 stroke oil and gas to get me going until i can get to the store tomorrow for my own oil. it started to run like a CHAMP i mean almost as good as before i took it to the shop BUT then i got home and right before i parked it, it bogged out and stalled like it was doing before, hesitating to move and rev up. spark plug was not fouled this time, he mentioned i might be getting WAY to much fuel (jet is to big). now it runs better with the snorkle in the air box. i did for my own feel better way, check the compression i am at about 115 to 120.


questions i have:
1. leaving the oil pump in, is that bad can anything get out that shouldnt, will it burn anything up other than the pumps gear wich i could care less about since the pump is shot anyways.

2. the guy who helped me asked about the crankcase oil. its never been changed if it has any idk whats all going on in there, but he told me to find out about changing that oil and my gear oil by the back tire.

3. will the oil from the leak still be working its way out since i disabled the oil pump?

4. will an over heating cvt case cause it to run like this or stall out? mine gets extremely hot like my exhaust almost lol

TOMORROW:
wait i cant think of what else to do LOL, thoughts here? i was told to get a new carb if i feel its still the issue, i didnt run it again with the gascap off yet but im thinking about just doing a manual petcock because its fairly cheap and easy to do to eliminate the vaccuum issue there.

well i forgot what else i wanted to say so when i think if it i will post it, thanks guys for being patient with me, im pretty new to this stuff and doing all i can with what i got. last but not least, a list of things ive done and how they effected or improved.

new variator from shop - way slower
put old one in with old rollers - gained 10 to 15mph
tuned carb- not sure yet LOL
removed oil injection system to a 45:1 mix - not sure of results (read above)
fuel injector/carb cleaner gas additive - nothing i know of changed
seafoam (one fresh tank of gas) - nothing changed
new fuel filter - nothing changed so i put old one back on for time being
checked EVERY connection of ANY kind on the moped

if i remember anything i didnt list ill let you know.

You only have gear oil. It oils the gears between the CVT and rear wheels' drive axle. You can buy gear oil at any hardware/autoparts store. It should take "100ml" I believe... The oil that comes in these things should be replaced immediately from the factory. I've heard of the factory using two stroke oil before. You probably won't notice any performance increase though. That's more of a reliability thing.

You can check to see if it is getting too much fuel by choking the intake. Run in on the stand in full rev and try covering that airbox inlet a tiny bit. If it revs higher; you need a smaller main jet in your carb.

I fully support your idea of going to manual petcock.

I don't think you have an electrical problem at this point. Only a fuel delivery issue.

Clean the vent in your gas cap.

I recommend the new filter. One, because it is new. Two, because it is always nice to know if your carb is getting fuel. You already discovered an issue with it on for a short time: the carb is burning fuel faster than your fuel system can deliver.

ok so im not sure whats going on now, just got home from work and decided i would try to start it and see how its runs after sitting a while and being completely cold, NO START, will not not matter what atm fire up, idk wtf is going on, im wondering it when we switched it to premix if some thing got messed up with petcock maybe and it just flooded my engine, it does turn over, just wont start. what should i look at first to see if i can maybe figure out why it wont start now.

Check for spark first. It's the fastest thing to check.

ok so i went outside to check a few things, i have spark, i have compression. not sure on the fuel tho, i changed back over to the new filter so i could at least see if gas was moving threw it when i was trying to start it, but it didnt fill up at all while trying to turn it over. i pulled the gas cap off and the snorkle back out of the air box and it almost fire up but the filter still had no fuel in it really at ALL, my plug was a little wet but not like it used to. im thinking its still a vac issue with the petcock maybe, so idk and i guess to be safe im gonna just do manual petcock, so what is a list of stuff i need to do manual petcock and once i get these parts what do i do about the vac line going intot he carb? also whats the best way to drain and refill the gear oil with new stuff.

well i have allthe stuff to install a manual petcock, just wondering still what i have to do with the vac hose that goes into the carb.

[maccrew]

sorry forgot to ask, do i need to put that intank filter back in also?

[jmkjr72]

if you have an external filter you dont need the filter on the petcock but your filter may clog up more often
cap the vacuum line off you can cut a couple inches off and thread a screw into it i likt to put a bit of formagasket on the screw before i twist it into the hose to plug it

[maccrew]

well i installed the manual petcock, theres an arrow on the valve what way should that face, is it possible that the thing can be backwards, the filter filled with fuel about half way right when i opened the valve but now no fuel is flowing into the filter that i can see unless its just a small amount, the filter stays a little under half full at all times, the vac hose is pluged with a bolt and a clamp, below is a pic of my new petcock assembly, also when it wouldnt start just now i covered the air inlet and it started, when i have it covered it idles up and when i let go of it, it idles down and kinda bogs out.

[maccrew]

ok the filter was filling almost full now after i got it to run and stay running, now like before after driving for a short amount of time (once warmed up good and warm) it stalls out, now it back fires when it stalls out. this is first time i noticed back fire.

ok i talked to a friend, he said these things to look into replacing/tuning, he said once its warmed up my carb might be tuned for cold running, not sure. he also said that he has had issues with the coil, when they start to go bad once they warm up they start to foul out and not spark because there over heating and same witht he cdi

[jmkjr72]

i would check your coil
your carb tune wouldnt change that much unless it was tuned at zero
before i switched to efi i tuned all my carbs around 40 deg that way at 20 deg i was lean but safe and 80 deg i was rich but not fouling plugs out

[maccrew]

how do i check the coil?

[jmkjr72]

you will need to check the resistance i dont know the specs for the clones off the top of my head and i think my zuma manual is on the other compueter still
