After getting the oil lines bled and all that fun stuff, I rolled her outside for the first start. Put entirely too much fuel in the tank before checking that the float valve and petcock were working. Last time I'll make that mistake. On the bright side, uncured Duplicolor engine enamel AND Rustoleum Appliance epoxy are both fuel resistant, which was surprising. Ended up with about a pint of fuel pissing out of the petcock all over the motor and walkway. Not sure what the deal is as I rebuilt the petcock. Going to pull it off and test it on the bench before I put any more fuel in the tank.

I actually managed to get her running after a few attempts. Since the petcock and float were both malfunctioning, it flooded out and died pretty quick. But I heard it run for a good 10 seconds, so there's that!

However, during this series of mishaps I discovered that the kickstarter gear is completely botched. The ratcheting mechanism only grabs about 10% of the time. So you can kick it over a couple times then bust your shin open when it doesn't engage. Awesome. I ordered a new assembly and annoyingly pulled the motor out to prepare to split the cases again.



On the plus side, this motor takes about 20 minutes to pull and it only weighs about 25 lbs, so it could be worse.

You sure it isn't just the drag spring on kickstart? very unusual for the gears to be trashed unless teeth are broken off

I'm not sure what it is exactly. Its probably the spring or a worn mechanism. The gear looked fine to the untrained eye when I put it back together. Either way, all that stuff happens between the crankcase halves, so they have to be split to assess the problem.

Getting close man, bet you're jonesing to get this thing mobile...

Just watched a couple of vids of 70's Van Van's doing laps of people's yards, wow these things look like a ton of fun.  Saw the 2018 model at the moto show this weekend which I'm sure is also loads of fun, but yours has it licked.  Hope you're on the road soon mate

The gears can 'look' completely worn out but still work , the internal springs always look OK(it's obvious when they are broken) but can be completely worn out.

I can't decide if I like the left side of the crankcase more or the right.

It's a split decision.

Thanks, I'll be here all week.

This little bugger is what’s giving me an issue. I ordered a spare gear set and it’s worn as well. Got a NOS pawl coming end of the week.

Sometimes NOS the best way to go.  Be done and forgotten.
