I can't find what exact "Evolution" model it is but here is the serial in case that helps
To do:
I'll give the bowl a good clean
Try a new plug
To do but need advise:
How do I test the head gasket without a compression tester ?
Not sure on how to test the ACR but I don't think that is the issue as it cranks just the same as before
Appreciate the assistance
