Latest post of the previous page:

What happens when you turn in the bypass screw out to increase the idle? Will the increased idle hold and stay at that RPM?

This is a decent article on adjusting that carb if you haven't seen it.

It doesn’t help. I have it turned out so that the screw head is about even with the hole it’s in. It’s turned way out at the moment.

I look forward to visiting this problem child.

Visited this problem child . . . we got it running well. Will write up in the Itinerary Forum.
So yeah, nobody gets no idle if it is at 16*ATDC!

Hope I’m not messing up the flow by jumping back to this thread but I have some news.....
Bus 1has been running better since Colin’s visit. However I have still had some issues with it. Left yesterday from windsurfing on the river and the bus just ran like shit. Pulled over and adjusted the new points I put in last week. Ran better but still had some strange stall out before it would run. Had to keep the rpms up. Just dug into it here at home and have decided that I have some issue with the distributor itself. When Colin was here we tried two different ones that I had with the same results. Well I just put together a third 205q dizzy that I have here and stuck it in Bus 1 and I think it’s really fixed now. I haven’t taken it out for a test run yet but I do have all vacuum hoses connected and fingers crossed it seems to be idleing real well etc. I’ll report back once I’ve driven it.
The dizzy that was in there seems really slack in the way the top part rotates. There is no resistance and it just feels really loose and sloppy. I’ll dig into it too and see if I can figure it out but for now I’m going for a drive to see if that was the issue.
I bet this is the problem. Distributor issues. More later.... :bounce:

That would be "missing or broken centrifugal advance spring/post". See wcfvw69 for details.

Here's hoping!

Right and that’s what I think it must be too. Haven’t dug into it yet. Took it for a drive and it does run better. Takes off in first gear easier without having to rev it up a bit. Been messing with the idle screw because it still idles low but not low like it’s going to die. Also reset the timing too. Seems pretty good though overall. I’ll keep driving it and see how things go. I’ll be looking for another 205 q at the swap this weekend.

Took Bus 1for another drive and it seems to be running really well now. Idles fine and can start off in 1st gear easily with no gas. The idle was a bit low on the first day but the second day it was a bit high so I turned the idle screw in a bit and now it’s just running great.
So I’ve decided I have a couple of distributors that have some issues. I will dig into them and see if I can figure out what the issues are. I used the same vacuum can that was on the distributor that I took out of bus 1 so I know the cans I have are good.
Feel great to have this running properly after literally years of dealing with different strange issues. :cyclopsani: :geek:

Yes, it has been a journey since we first met at Maupin . . . now you have two buses to go.
