Thank you.
I now have a better understanding of your build.
If you need a spacer in the future contact Cometic Gasket, send a sample base gasket in and they can Water Jet cut whatever thickness you
need in Alum.

You need the formulas? Then I'd need more info as well ,, weights ,, stroke length,, rod angularity ,,, ect to calculate the actual forces ,, me thinks it's a simple matter of mismatched swage angles and the nut not being able to be tightened enough to stop the movement ,,, then the key shears No, no ,no I wasn't going in the direction of what I asked is the problem I'm just technically curious. I have the formulas. Hope I didn't scare the poster off. |

Roy has the answer i think,,a missmatched swage and a junk metal key,,,,with all thats going on with the mill,(big stroke,,lightened everything),,,i think when the decelleration and acceleration of the rotational mass happens after the polar moment of the piston BAM instant bummer,,, Ahhhhh, I think your on to something. I just like to ave the technical known data to procede. |

Hey Alley, I have a new one that is going on. However the old one is still in great condition. But to make sure that that is not an issue I just got a new one. Before I put this thing together I am not going to encounter the same problem. Now I have made several mistake when I built this engine and I wondering if a high compression issue combined with running high octane fuel would have caused this to happen. Now when it was running it ran like a bat out of hell, but this time I can not run that high test stuff. Caused to many heating issues. Curious, What Static or advertised Compression ratio are you running? You Mentioned Shaved piston, Shaved as in internal Weight reduction or Shaped to Slipper Skirt or Removed material off the dome to lower Compression Ratio? High octane Fuel Should not cause any Heating issues, it burns slower and more controlled for higher compression engines. Running Low Octane in a High Compression engine will cause Preignition, Detonation and Heat issues. High Octane in a Stocker GY-6 will do nothing but waste money. |

I removed enrichner per post here..used gasket material to block holes..even blocked large opening where enrichner needle went..may have found problem.. Lot of slack at throttle to carb cable..tightened it up seems to make diff..still got A/F screw at 1/4 turn from closed..runnin fine performance wise.. Just concerned that its too lean n I'm gonna burn engine up..how bout a recommendation fer a good cdi/ coil? Or are they basically all the same? Thanx n keep the rubber down Don't be too concerned bout burning it up/Siezure. Your jetting will have to be waaaaaaay out to lunch. She runs in a bath of oil, very forgiving. Now a Two Smoker would be a different animal. |

K
Already have some Bellray 10w
Think I'll add a extra oz.
The issue seems to get worse the faster I go. 45+mph
Gunna have to try those Ceramic Tire beads also.
don't like this surprise "Peek a boo Moments"

May I add one of the toughest job your Oil has is when the piston decelerates at the top of the bore
On a engine with hours we find that ridge worn in the bore were the ring stops at TDC.
Explain. Pour water on your counter or a piece of glass, then take a Squidgy and swipe it across the water as fast as you can.
It hydroplanes and leaves a thin layer of water.
Now do the same test only move the Squidgy slowly. you have removed all the water, none left, dry.
That's what the rings are doing as the Piston slows down coming up to the top of the stroke and reversing direction.
Tough job for any Oil.

Works every time. almost
Back in the days I was working on a IH 1428. Farm tractor.
428 CI Diesel Knocking.
Knock came from up top, Hmmm, was using Stethoscope.
It had spun a rod bearing and the Piston was hitting the head, the sound of the piston hitting the head seemed to cancel out the rod knock.
Just sayin.
