Bolt,​​ Stud (fan Cover) 90043-Z8B-000

Had to unscrew mounting bolt out of the engine and then used Vise Grip to hold bolt to undo the nut that held the starter coil/gas tank to gether. Only way to get a good hold with vise grips on the right side was on the threaded part that screwed into the engine. The left side did the same thing but was able to get apart without damage. There are three bolts in a triangular pattern to hold the gas tank and rope coil onto the mower. Must have got one of the two parts out of alignment when reassembly after replacing a Governor return spring on Honda HRX 217 mower. It caused the nut to grip tighter than normal unscrewing the bolt out of then engine. Got my bolt from E replacement fast and was an OEM Honda part that worked perfect. Had the mower tank off and replaced the part and mower running in no time.
