K301 Timing

[bschmittling]

I have a 124 with a Bosh coil and point saver. The points slipped and stayed open all the time so I had to re-time it. The previous owner put a nice white timing mark on the flywheel so I used that and gapped the points at 0.02. It runs and idles really smooth now but hits really hard at least once every time I try and start it. It hits so hard the starter will stop rotating. Is the timing too advanced and do I need to gap it at 0.018 to correct it? Thanks

Time it this way, don't worry about the gap.

My mallware blocks the link.

Put it in the list of accepted sites. Sorry if that sounds blunt, but it's much easier for you to read through Matt's link than to write a whole new one explaining it.

I will try again tonight on a different computer. Thanks

Time that engine according to the instructions that came with David Kirks point saver. I have also found that if remove the original adjusting screw from the points and replace with an allen head screw the points will stay where you want them.

I think you might have a compression release issue. My 108 does this-it's like the starter can't turn over the engine against the compression and the belt squeals as the starter pulley slips. It "hits" once, then fires right off, so I haven't taken the time to fix it right yet. Need to get the grass cut!

I think you can open the cam cover on the left side of the engine and manipulate the spring on the cam (if it's not broken) back into place to get the compression release to work again. Or so I've read on other threads here, but have never attempted it myself. (yet).

Your are Welcome.

If the problem persists after the spark timing procedure already outlined has been performed, try using a premium fuel. Ethanol enhanced fuels cause all kinds of peculiar problems in older engines.
