Been working steadly on fixing my 1974 1.8L.
New injectors,plugs,Petronic point replacemnt.etc. Driving to the store when all of a sudden something happened. Car felt like it had dropped 1 of the cylinders. Car does not rev at all,made it home and parked it. Diid a compression test (cold),110 110 100 90. Not happy with 90 on cylinder 1 but felt at least like motor should still be running. Where do I go next.???? I have a dual vacuum line throttle body,and a single vacum on my for sure non stock distributor that had a 4500 RPm rev limiter. (Distribitor mark for cylinder 1 is 180 degrees out.) Like I said I put on a pertronic 1847 and a petronic blaster coil and 8MM wires. I am thinking its a spark think,but really dont know what to do at this point. I have ordered a Mallory Unilite distribitor(4554101),but wont install it till I figure this out. Hoping for some help from you guys. Thanks Grant. |

I don't think those compression numbers are that bad. Shouldn't cause one of the cylinders to not fire.
Which cylinder is it? Is it the one with the low compression? Check wires and plugs. Shouldn't be the Pertronix if the other cylinders are firing. |

QUOTE(Spoke @ Aug 26 2015, 07:31 PM)  I don't think those compression numbers are that bad. Shouldn't cause one of the cylinders to not fire. Which cylinder is it? Is it the one with the low compression? Check wires and plugs. Shouldn't be the Pertronix if the other cylinders are firing. I am not sure which cylinder is not firing. There was one spark plug that was slightly wet but the compression is 110. Really just trying to figure out what to do next. The spark plug wires are brand new,but 1 fell apart while pulling it out,so Ill try and fix it. I ordered new plug wires just to eliminate the possibility they are bad. I will try and test tonight and see which cylinder is not firing. When turning over cylinder 1 it makes a weird noise and it is the lower compression cylinder. With the distiritor 180 degrees out,I am not that confident with the timing I set it at. I am also concerned they adjusted my valves when they did the timing,car does not catch well when turning over. Ill start with plug wires and see where that tales me. I will have to try and check my timing as well,not having much luck finding TDC though. Thanks for your help. |
