OK, to be clear: We are waiting on Apricot to see if his engine turns over correctly by jump-starting from a known good car battery (car NOT running) directly to the screw on the starter where the large red wire attaches. The black jumper cable should attach to ground - if possible, directly to where the starter motor attaches to the case. I thought that was with the car running while revving it to about 6k rpm ? |

Its looking like it could be the starter clutch .

Its looking like it could be the starter clutch . I dunno - at this point I'm really surprised and flummoxed. I assume the jumper cables were connected normally, and it's now verified this is NOT an electrical issue (which is stunning to me). But at this point i have no idea what to do next short of starting to tear the engine apart, which is a crappy dilemma. |

This^ Bent rod, timing chain stuck, cam bearing failure, faulty valves, something around those lines could be the issue; if it doesn't spin freely, taking the engine apart is the only way to find out the issue. |

This^ Bent rod, timing chain stuck, cam bearing failure, faulty valves, something around those lines could be the issue; if it doesn't spin freely, taking the engine apart is the only way to find out the issue. But it DOES spin freely! He took the plug out and the thing spun like a top. Without compression there is no problem spinning the engine. so ..... does anyone have any suggestions of how to DIAGNOSE what's up from among the many possibilities - so he can logically go from here, rather than just disassembling everything in the hopes of finding something??? |

ok people, next step is to check the starter clutch,lol. he has the same issue i had, yes it may not be it, but at this point he has to check , right.

we must eliminate the starter clutch at this point.

it will take him no more than an hour to check the starter clutch. the only issue is that he will need a flywheel puller . he dosent need a starter clutch nut socket. he can use a pair of vise grips on the starter clutch nut and a socket wrench on the variator nut to remove the starter clutch nut and put it back on. just remember the starter clutch nut is reverse threaded. u can use a ssteering wheel puller on the flywheel , but you will have tto use one that will work.

have to post picks of the starter clutch and the clutch gear. he will hae to look for signs of slippage on the outer inner part of the gear where the rollers contact it. the first time mine went bad i didnt see much damage but after replacing it everything was perfect. of course the first time i just had a weird noise no issue starting , but the second time i had the same issue when trying to start.

we must eliminate the starter clutch at this point. I agree it "might" be the starter clutch .... or something in the jug .... or bad bearings ..... But whatever it is shows up under compression but not with the spark plug removed. That should give us a clue (I know, it STILL might be the clutch ... but doesn't this make something else - like, maybe, valve timing - more likely?). Someone here should be able to point out the next most likely cause from among the many possibilities. |

Someone here should be able to point out the next most likely cause from among the many possibilities. I guarantee if I removed my spark plug , my starter clutch would not have slipped like it was doing . the compression makes it that much harder for a slipping starter clutch to turn the crank. I would imagine if bearings where bad you would hear some noise. It is still hard to say what is wrong , but at this point he has to tear something apart and the side cover is not hard to do . |

Isn't the jug new ? If so , the problem existed with the old one also . so that would rule that out.
