Mag Drop

[Big Ben]

Saturday went to take the cub up for the first time since my 7.5 hour Lompoc flight. Get to the run up area and check mags. Usually I get about a 25 to 50 RPM drop (new slicks). This time one side gives me a 300 RPM drop and noticable roughness. After taxing back with my tail between my legs. I check and clean all plugs assuming that they are fouled. Upon restart, the drop and roughness continues.

Any insight or suggestions before I take it to the shop?

Thanks, Ben
