What am I doing wrong? Update in post 16

Just put a shim ( washer ) on the inside of the small drive sprocket. You will in turn need to shim the driver the same amount as it will move the driven clutch sideways the amount of the thickness of the shim. How much do you need to move it over. Also just a thought, I once had a similar problem. I discovered I was using a #40 chain, which is wider than a #420 chain. Not a lot but it was enough to make the difference. If you are getting into thousandth of a inch, and I bet you are, you could even grind down the bolt head. If it has a washer behind it remove it. How about a Allen head bolt. That could ground down much lower than a standard hex head and still be able to engage a standard key to tighten or remove. This is something I 'm sure you will be able to overcome.

I will have to check that all out. I was joking with my wife that the bolt head was self clearancing, she didn't get it.

I believe that there is supposed to be a spacer washer between the jackshaft mount and the gear which I am not seeing. I could be wrong, so wait until someone more familiar / knowledgeable chimes in. And I have the old Yerf Dog jackshaft plate that I can measure for you if it helps.

I will have to check for a washer.

That looks like the exact same thing I have.
I'm thinking I should just get a new TC with mounting plate that mounts to the engine. That way I know it will line up.

I was trying to re-use this one since panchothedog was talking about the 7in driven pulley being better than the replacement 6in driven pulley.

At this point I've sent $40 on that plate from BMI that I probably can't return. So I don't know that I want to bother with anything else that MIGHT work.

Am I wrong?

You say it LOOKS like the exact same thing you have but it isn't. The mount plate link I sent is for a Yerf-Dog and sits higher than the generic red plate you have sandwiched in between the other ones. Refer to the images provided.

Here's a view from a Manco kart, the engine sits higher and allows more clearance. I would raise the engine or mount plate somehow & see if that gives you a better setup.

Part #2 in the image, the stud, is what should help you. Come up with something like that.

After taking another look at your red mounting plate it is similar to what I suggested. My apologies. I think lifting the engine up will give you the correct clearances. You may have to add links to your chain or pick up a longer one though.

Oh that's an idea. I will have to get some longer bolts and some spacers and try that.
I need a new chain anyway, the one on there is no good, I was using it to mock everything up.

I think the red one I have pictured is original from a Yerf Dog. I think I want to separate the engine from the TC plate though, as opposed to the engine and TC from the engine mounting plate on the kart. I will have to check I out.
