I'm having issues getting my moped started and running. It's a Safari MT300 (1975 I think). All I know about it's history is that it supposedly needed a new head and piston.
So I tested compression twice and got readings of 125 and 135 PSI. Out of curiosity I took apart the engine and all looked fine. A couple of scratches here and there but nothing major or deep. The rings were nice and loose too.
I rebuilt the carb as well, didnt see much dirt in it though. I know I'm getting spark as well. Not sure if it makes any difference but I grounded the spark plug with a jumper cable to the metal foot rest to test for spark. The spark plug looks unused as well. The head is black but the tip look nice crisp and sharp. And I know I'm getting fuel to the spark plug since I saw it was wet when I removed it after trying to start the engine a few times.
The air box is hollow with no obtrusion's so I just cleaned it up. Cant imagine its an issue with air restriction.
At this point, I'm thinking it might be an issue with timing. My experience with motorcycles/mopeds/2 strokes is very limited so I'm not sure how to adjust timing. Any help or tips would be greatly appreciated.
