the coils and pack in 2 and 4 is new sparking fine. i swapped 2 and 4 just to check but was a no go. they are not reversed. i was very careful not to swap when i replaced coils. i tried it to rule it out. backfired and wouldnt start when i pulled 1 and 3 wires and isolated 2 and 4.
also re did a spark check after compression test. all 4 have bright blue spark. 1 and 3 are on old power pack and running 2 and 4 are on a new pack. so im wondering about possible flooding cause the plugs are always wet after i pull them. i had a force 50 that would drop a cylinder after about...
my old push on tester was showing around 110 115 ish on all 4. this was cold cranking i should do a warm up test tomorrow but 2-4 really never get to operating temp. but warm up some from the other side.
so i went today and got a screw in compression tester from the parts store. mine was a gauge with a rubber nipple thats pressed into the plug hole. so i figured i would do a test with a better one to rule it out. and much to my happiness they are better. starting with cylinder 1 and so on. 120...
i swapped the coil wires yesterday. and started it. got a few backfires. pretty sure thats not the case. and this was happening before i put the new coils on it. plus that first trip this spring when it ran great and doubled the speed.
yes the
compression tester is good. i did relief it between each cylinder. plugs are brand new. when i rebuilt my chrysler 2 years ago the same tester read 150 148 150 on the 3 cylinders after rebuild. all 4 have between 110 115ish compression. when we went out to test and set timing i used 9...
problem is, i just replaced the stator rectifier and timer base within the past 2 weeks. the 4 coils a month ago. and power packs today. ignition system is new. these cylinders wont run at all. cold or hot.
ok. basically one power pack was bad. put on the old one that worked. so with the new and the old that worked i have all 4 getting good spark that will jump to ground over 3/4" . compression cold cranking is 115ish on all 4 give or take 1or 2 lbs. all very close. the starboard side is running...
Starting new thread for correct title. Ok so heres my issue. checked compression. 118 in all 4. new timer base new stator new coils and packs new rectifier. I have spark on all 4 and the spark jumps good and bright over 1/2 inch. port side cylinders 2 and 4 are not running. It did first trip out...
compression is 118 almost exact on all cylinders. found out that one of the power packs was defective. the old one fired on both new on only one. so with the good old one and one good new one i have spark on all clyinders. the root problem i have found is only cylinder 1 and 3 are working. the...
