The old 1983 carb blues

Hey there – I’m new to the forum. Looks like a nice place so thanks! Would love a link, thread or any insight to my Atc 70 issue if possible-

She’s a strong runner and bigger sprocket. But won’t start unless fresh new gas and plug. Then that only lasts a few days or maybe a few weeks tops.

I had the dealer tune it up once or twice in the past – not sure to what extent but I think they worked on the timing chain ? I don’t know what really and I’m petty much unfamiliar with the mechanics of these. But, I enjoyed pulling the carb, cleaning it carefully etc. Seemed to help for a little while.

Few thoughts might be…
– bad gas these days
– bad stabil in the gas or not enough ?
– bad jetting
– air screw mixture (that helps a little when I try to dial that in but I’m guessing)
– bad plug gap? They foul pretty quick
– get some oem carb Kit and replace o-rings and jets?
– drain the gas each time since we don’t use it very much

Thanks guys. Happy new year
