Re: Lotus Esprit with low compression

Hello again Alan thanks that makes sence of my findings,assuming im right? lotus.net has lots of info. should we concentrate on cranking waves first? that compression loss should show somewhere? and would expect you have access to a few transducers? cover all possible areas of leaks. look forward to...
