HI, I need some advice/help regarding the TT21 OB. I recently modded mine and it was running well, then I decided to mod further removed material from the shim to get .008" headspace. However when I reassembled the engine, I found that the compression is very low when turned by hand. Is this normal for the mods I did? Or could it be that I now have got a bad seal between the sleeve and the button?
I am quite new to engine modding, so any help would be appreciated
