    ive been a small engine mechanic for about 24 years 2 years in shop and about 20 years of maintaining and repairing the engines for my lawn service for friends and family too during that time ive seen quite a few broken off bolts in crankshafts ican tell you you ddnt need to remove that crankshaft at all you could have used a pair of needle nose pliers and turned that bolt out in a mower cranks the bolt doesnt bottom out against the the end of the threaded hole so when they break off the piece remaining inside the cranshaft is in there loosely and just back out easily and generally the threads arent damaged at all
    i applaud you for trying to do your own repairs but consulting with an experienced and competent small engine mechanic would haved saved you the price of a crankshaft and who knows how much time
    Edit the reason that bolt broke off in the first place is it was most likely over torqued those bolts dont have to be torqued very tight to prevent a pulley from walking off the crankshaft look up maximum torque specs for that diameter bolt
    if bolt is of chinese origin only torque to half the max torque specs for that diameter bolt not trying tras the honda cline engines but im saying the chinese always lie about the grade of the bolts

    Same thing happened to my buddy on his bike. If you know somebody that can tap it they can pull out the rest of the bolt won’t have to replace the crankshaft

      it'll probably cost the same amount. tapping it and inserting threads might cost even more

    drill use easy out and chase the threads with a tap easy peasy 20 bucks

    cutting that spark plug will and there by making you spark plug larger give the spark a larger gap to jump that is decresing the efficiency of the plug its likely though that decrease in power will only be noticeable on a small engine dyno please kid stop listening to who ever is giving you information theyre giving you bad information also that increased plug gap could cause a hard start no start issue as the ignotion components age and go through hundreds of heating and cooling cycles

      i don't know man, i haven't had a problem with it. i think it depends where you cut the plug at, some people cut stupid and thats mostly likely why they say it doesn't work

      @Nxcho9 ill admit that some people probably do cut to much but cutting it at all is increasing the distance the spark has to travel its better to keep a plug with the factory gap setting and proper heat range in the engine it should be noted that these honda clone engines come with a really crappy sparg plug factory installed there sometimes labled torch or no name at all ive had them fail on me
      for no apparent reason and there is a vide here on youtube of the plug failing in less than 30 minutes after a mini bike was unboxed and on its first ride and theres plenty of videos of people telling you to
      change the plug immediately they aint kidding your plug looks like an autolite plug i have those in all my predator engines as well as the other chinese honda clone engines that i have
      all total i have had 6 of them some the plugs lasted as much as 30 hours some lasted as little 2 hours the one in my generator (homemade alternator generator) actually went bad while the generator wasnt being used when i went to crank it up it would backfire through the muffller and or carb when i figured out that the plug was the issue i changed it and the generator started immediately and ran normally and hasnt had an issue since

    Holy hell dude you replaced a non sealed bearing with a sealed baron you never do that on a 4 stroke engine the engine oil is what lubricates the bearing the sealed bearing is sealed so it cant be splash lubricated by the engine oil you can be certain that bearing will fail

      if you can't tell i did take the seal off before installing it 19:13

      @@Nxcho9 i didnt notice but its a goo thing you did but dont those engines have an oil seal that goes around the cranks shaft and presses into the side plate
