How to get the mech. advance off

So the bolt is broke off in the top left. I tried extracting it with everything on. But I'm just spinning my wheels. So to take the whole housing off is what I need to do. But the advance is a little hard getting off. Do I just spin the 13mm bolt counterclockwise that is on the 17mm bolt while holding the 17mm bolt steady? I do not want to cause anymore damage than what I am trying to get fixed. That little 13mm bolt doesn't want to budge.

Yes you can just lossen the 13mm bolt and that will allow you to remove the advancer.

counterclockwise?

It may have corroded threads; try soaking it with Kroil for a day or two.

Yes, counterclockwise. If you don't have any Kroil, Liquid Wrench penetrating lubricant is a good one & cheap. Apply the penetrant & let it soak for a while. You could wipe off the excess, warm up the engine, then apply some more & let it soak. Also, if need be, use a wood block & mallet to tap the bolt - vibration helps to loosen stuck bolts. Apply some more penetrant.

Got it off. Just needed a little help from the cheater bar. SO now there is the oil seal. I couldn't find any definite answers in the manual . But I hope the can of worms I am opening doesn't cost me more time and money. I just need the rh engine cover out of the way to tap a new thread . Any important info before I goand try prying off the rh cover?

stupid worries. sorry. i got it off just fine. now the hunt on for 7mm helicoil.

You are going to need the 6x1 mm helicoil.

No. I used a .25 to get the trash out. I thought of just jb welding .25 helicoil in there since it's non load bearing. The hole is at .288 now. Any ideas that are better than mine? Really i thought the next size is an m7.

Which oil seal?

with the advance off there is a rubber oil seal right there. When I got the bolts removed I gently pried on the housing and everything came off smoothly.

the rubber piece I was talking about. I was hoping it wouldn't become damaged from taking the housing off the crank case was all. When I am doing something for the first time I get worried that the lesson learned will be a valuable one
