here are the symptoms, guess the cause
Here are the symptoms, guess the cause: Pre-ignition under load, running hot under load, decrease in power, rolling idle.
First to get it right wins. (You get nothing if you win, except satisfaction) |

Re: here are the symptoms, guess the cause
Would rather comment on what you think is a logical plan of attack.

Re: here are the symptoms, guess the cause
Too much spark advance (19 degrees) like you get when using A distributor with Model B timing cover.
Lean carb will do it also. Last edited by Benson; 08-17-2018 at 01:23 PM. |

Re: here are the symptoms, guess the cause
Ok, I'll show my hand. I did a quick compression check by cranking over the engine by hand, and it sure felt like the compression was off on a couple cylinders. Pulled the head and sure'nuff, the head gasket had blown between 3 and 4.

Re: here are the symptoms, guess the cause
Only If your on the left side and your right handed.
If your on the right side and your left handed it would be 3 and 4 If your on the left side and your left handed it would also be 3 and 4 If your on the right side and your left handed you are in the wrong place. If you are ambidextrous you have to count 1, 2, 3, 4 and subtract one from the last number to get the first number then add one to it to get the second number. You could also count 1, 2, 3, 4 select the last number for the first one and then subtract one to get the second. You could also say the it is the cylinder closest to the firewall and the one that is next to it. Just Saying! |

Re: here are the symptoms, guess the cause
Curious, before you pulled the head did you do a compression check?
