several problems, working on them 1 at a time
ok have a 82 Atomic 4 fresh water great lakes cooled with mostly all new parts and updates, to list a few rebuilt zenith 68 carb, new exhaust hose,new fuel and vent lines, new fuel tank pick up tube and check valve,new water lift muffler system,all new tune up wires,plugs points,cap and condenser, new coil, and so on.
1. Smoking and poor performance would pop up see you tube video
after running 4- 5 hours each time After reading up on symtoms I found that stuck valves were one symptom's of mine and a soaking in the holes with MMO was in need, this helped
you tube video after soaking valves in MMO for short time now I am soaking them a week!
compression no#s
cold wet compression no#s ,138,130,121,120
hot dry no oil in hole after running 90's all holes
just soaking valves in MMO for a few hours!
shot oil warm 130,129,130,130
and now I know I need to prevent back pressure on my exhaust to prevent this as my exhaust port was under water with a OVER-loaded cockpit and large dink motor on the back , this is no more. so one problem may be solved I have ok compression, no water in oil, no oil consumption at all, and with hand over flame arrestor lots of suction leaving out a intake gasket leak and I have checked carb for vacume leaks none,,
2. next a Atomic 4 wiring is not too complicated but I have a symptom thats going to be hard to crack but with the engine running good as soon as it starts to act up like start to miss a bit the radio CD player starts to act up fade in and out never did this and sonar speed indicators act up too, I jumped on sanding all the grounds on engine checked loose wires on ignition switch not, battery's all connections tight and I am looking at all the buss bars and will make and bring up some jumper cables to isolate the electronic devices this way and see if the symptoms stop?
Could the ignition switch have any thing to do with this as the electronic radio and speed / sonar do not run thru this switch? or the alternator developed a blown diode and shooting A/c into system I guess I can pull belt off alternator and see if this stops, as I have a new resistor coil in this is not a bad coil, & I will chase all grounds and hot leads and file and sand clean all contact connection points I have been doing this now,,
3. lastly my points are new and I do make sure they are clean before instal and set them .18 to .20 and tighten them down and after I put cap back on engine runs fine for a while then as engine acts up I re check or and re set and check points and then it runs fine for a while?? points don't look burnt or fried out as they look new and they are,,
my distributer seems to have a working mechanical advance as it snaps back is good, I will set advance next but when engine runs good it runs good under load or not is there a symptom or a cause? or is it just the engine gremlins!!
any ideas as I think I had several problems with one masking another but am working my way thru this!
Thanks any help
