    That’s very helpful aquasonic.

    I have been fiddling with the low speed needle but will try if richening it more will improve things.

    The entire fuel system has been cleaned, but I’ll go over it again. I will also have another look at the head gasket. I was actually odisappointed by these low compression numbers after having replaced the piston rings and head gasket. Of course there can be numerous other reasons for that, but I want to rule out the gasket. The head has been lapped and is flat.
