Looper Shutdown with a rattle noise

[THEFERMANATOR]

The sea-drives all had the 35 amps systems as well, but not many 120/140's did. I've considered finding a blown V-6 and swapping the stator and flywheel over to my 140 to get the higher output charging system. The factory charging system on the early V4 loopers SUCKS! I got a whopping 1.3 amps at idle, and 3.6 amps at 3500. 5000 got me up to 6.3 and 6100 got me 8.56 amps(I guess just enough to call it a 9 amp system). This was with a new stator and rectifier.

When you say it acted like a dead battery after a hard run, that is a direct indicator of a stuck piston. Chances are you smeared it when you tried to start it and it didn't kick right off. The rattling is most likely a smeared piston skirt that is rattling against the cylinder wall. Been there, done that. 140 is hot if that is what it was cruising, an old school looper should run 140-170 at idle and IMMEDIATLEY drop to about 100-120 at 3000-4500 and bump 130 maybe 135 under WOT on a hot day. Pull the head on that side and look for signs of aluminum stuck to the cylinder walls, but the head needs to come off.

Let me know if it's bad, my 140 could be made available if it's bad and you don't want to build it.

Ferm,
Thanks for the offer PM me please with the details and asking price of your 140 I may just install a new motor at this point and keep mine as a spare.
My bad spell never seem to end, Last week Trailer Stolen, I was in the ER two days later with chest pains , now blown looper !

Thanks ,

I cannot offer one word of advice here, but just chiming in to say sorry for all your troubles, and glad to hear the chest pains were apparently not too serious. They say bad luck runs in threes, and you have had your three early in the season, so hopefully it is smooth sailing from here on.

Holy cow Andrew, if it wasnt for bad luck you'd have no luck at all. Hang in there, this too shall pass.

Thanks Guys for all the kind words I am feeling much better. All my test came back negative. Low potassium was the culprit for the chest pains, I have since added OJ and bananas to my diet.
Hopefully they will add potassium to my beer and I be ok.
I pull both heads no sign of damage. Maybe broken reeds ?

check the flywheel nut, make sure the flywheel is tight. I had a merc that was making rattling noises, found out the flywheel was loose, had to replace the flywheel.

you can't install a V6 flywheel on a V4 been there and the 35 amp V4 has a smaller flywheel and the V6 will not clear the starter nor the carbs, you must use a V4 35 amp set up


hey post us a pic of your flywheel so we can see which you have. and the pistons and cylinders look fine um will it turn by hand and if so any tight spots?

[nymack66]

Ok I will check tomorrow..
