I just recently purchased an American Triped mfr. in 1979. It has a motori minarelli engine. I was not told the gas and oil mixture, so I called my local scooter dealer and was told I could use the same oil as my honda express (yamalube) at 32:1 so I did! It ran about 2 blocks and died. I have not been able to get it started again. I dont know what size engine it is and have no Specs. at all. I looked the eng over for numbers but only fond one on the plastic air breather cover # S1 DGM 9560- S I think it is a 50cc. I dont seem to be getting any fire at the plug and compression is 80 lbs. Would appreciate any help you can give . Hallsgates
