This has been a stressful mb week for me. I just replaced my old 48cc jug with a new ported jug with a rounded exhaust port and 40mm intake ( yes you heard that right ) and skirted piston. I ran it, it was great. But I noticed that it sounded like it might be running a little lean, ran it a few more times let it cool and checked the spark plug and it was a light tan bordering white so I dropped the clip one notch and rode it. After 10ish minutes it started to bog down and could only go half throttle And i heard a weird noise think it was the sound of air going through my exhaust gasket (didn’t realize it at the time) so i got it home started it and saw smoke cpming out of the head area so i put the head gasket back on put the needle back to the original notch. next day took it out could only hit 20-25 and maybe 30 on a slight decline. And it would die going up a hill.
I got it home and saw that the exhaust gasket was split on one side so i changed it and I rotated the motor so the carb would be slightly angled up i can make it most of the way up that hill (its about a block) but still dies near the top i also peddling, but i can turn around to head back and it fires right back up and ready to go.
So after my long story, does it sound like im not getting enough gas?
