Hi.
Ill try to be brief. We’ve done the carb kit, filters and replaced the coil and plug twice. Sparks good so we check the compression using the decompression port and it’s at 75psi. I understand it’s supposed to be maybe 150. I’ve taken the cylinder off but the piston, rings and cylinder look sweet. Nice and smooth, no scoring, rings are good. Doesnt look like it’s done much as there’s only minimal carbon. Ideas please ?
