Re: 1958 Fastwin cylinder psi mismatch - concerns
It might run if you had good spark.... you'll never get that motor started with cracked coils.<br /><br />40 psi diff is not so good either but the motor should at least run, albeit poorly. You may have a bad head gasket; or, perhaps if you get it running you can run some Seafoam or other decarbonizing spray thru the motor in hopes of freeing up the rings. If your motor has intake port covers, they can be easily removed to check the condition of the rings. Or, pull the head and check the pistons/bores. <br /><br />Check the head gasket for leakage and if you see an uneven clamping pattern on the gasket, likely the head is warped and needs to be milled flat. Or you could do it yourself with wet/dry sandpaper on a thick piece of glass.<br /><br />But those coils aren't going to cut it. Any old JohnRude with cracked or oozing coils is going to have spark problems. Replace the coils and it should run.<br /><br />HTH.........ed
