Today I finally had a chance to fix the hood on my "worker" EK10 that takes care of lawn mowing and snow removal.
The hoods were made out of aluminum and 40+ years of lifting and vibration wears the holes out and lets the hood rattle and move around making an annoying noise while the engine runs that often blocks out the muffler noise!
Figured I'd post this so others with the same problem can fix their hoods.
All you do is remove the hood, clean the area, fill holes with JB Weld (I use JB Quick) and let dry.
Drill out holes back to spec at 3/8'' and reinstall the hood.
I did this when I restored my 1969 EK10 but dont think I posted this. All Estate Keepers I have come across all had this problem except the new one I just got that was hardly used.
