Tonight I was adjusting the idle speed on my HRX217HXA because on low speed it was way too low. I have a Sendec hour meter / rpm guage and it was idling in slow at about 1200 RPM. It was hard to get in even with a longer screwdriver to adjust the carb but I got that dialed in perfect and only burned my finger once as the mower was up to operating temps. In the process, I knocked the breather hose off the back of the air cleaner housing and could not get it back on. I had to loosen the bolts for the air cleaner housing, and the throttle control bracket in order to get enough room to put the hose back on. When I tightened the bolts back down, I followed the torque spec per the shop manual I have for the mower, which is 7.2 ft lbs. All 3 inside the air cleaner tightened down normally to spec, but the one below decided to strip out. It happened so fast it was too late to "stop". The bolt will still get "snug" but definately may work loose.
After saying a few choice words, I mowed the lawn and put it away. It's got 72.2 hours on the mower now, it's a 2007 model.
I'm a very handy guy, but I'm kind of worried that this won't be an easy fix. Has anyone ever used these Helicoil repair kits? If so, any tips?
My other thought would be to just put some loc tight on the thread and get it "snug", and hopefully it won't work out again.
I have a feeling it stripped out because the block was hot and the aluminum was softer. I should have waited for it to cool off before torquing it I guess
