A previous thread raises an interesting question: Would it be better to control the compression ratio by using thicker cylinder to crankcase gaskets, or by milling out some material from the cylinder head combustion chamber?
I happen to have a T-IV engine with .123 inch deck height and 53 cc heads, giving an 8.5 : 1 compression. No gasket at cylinder head, only gasket(s) at the crankcase. I did not build the engine, but some folks seem to think .123 is a bit "tall". I'd have to agree, but the engine runs fine with good power. Will this end up being a long term sealing issue?
Anyone with experience? I know someone will have an opinion! Thanks.
