Car did not want to start. Gravity fed petrol through pump but to no avail. Found 2 fractured rubber lines at the carb, so temporarily taped them up. Still no different. Recharged battery, and still no change, so cleaned battery terminals and the clamps, whilst doing this noticed the negative cable has deteriorated significantly and almost fell out the clamp crimp. Repaired this cable with a spare one from the boot of this car. Car now works, video below. It’ll be a long time before the car runs again, here on begins the major stuff.

Car started straight away today. Thought I’d do the cylinder compression test again before moving on to test the intake and fuel fump vacuum pressures. But, battery run out after the compression test, so intake vacuum will have to be tomorrow. The difference in results from yesterday, although minor, are probably due to the engine being hotter as the test was conducted quicker this time round. Curious why number 4 is all fine today…

Compression test.

1 April 2008

Car would not start today. Ha. Gravity fed petrol into pump then reattached fuel lines and car runs. Unsure of problem. Performed compression tests on the cylinders of the engine. An engine overhaul is intended (new gaskets, piston rings etc.) but this test should flag up any serious problems. Diagnosed two cylinders as faulty, numbers 1 and 4. Performed Wet test (oil in spark plug hole) and improved results, for number 1 only slightly but for number 4 put the compression to the second highest of all cylinders. This indicates a piston ring wear problem in cylinder 4 and possibly 1, unsure as to the exact problem for number 1, will have to wait untill the engine’s stripped.

Recharged battery back in. Replaced the sheared and rusty battery clip bolts. Engine turns over at a greater rate and sounds somewhat healthy but doesn’t fire. Battery was part of the problem, must have lost it’s charge in transit. 10L of petrol put in, no change.

 

Problem must lie with either igniton electrics or fuel system. Quickly tested, there are sparks at all spark plug leads.
