Taking manifold off

Finally got all parts to rebuild the hot section of my leaking exhaust and just started trying to unscrew the bolts. Those are pretty rusty. I'll continue spraying with PB but it does not look like I'll be able to get them lose. It's not easy to reach them with a wrench. I would not dare to heat those with a torch near the fuel lines and the gas tank.
So, I thought to take the manifold off along with the exhaust is not a bad idea. I should be able to do something with the stuck bolts in my garage.
It looks like I just need to unscrew the three nuts on the side and take the carb off.

Yes that would work. One downside is that holding the manifold securely while torquing and/or banging to get the bolts out. When you replace the exhaust use studs as rework will be much easier.

I agree. I had to remove the manifold to get at my stuck bolts. (Replace them with SS studs, or at least SS bolts)

If you do this, be sure to order a new manifold gasket, as you will likely destroy the old one when removing the manifold.

Because gaskets are so cheap in relation to the fixed shipping charge, I like to always throw in a few gaskets on every order I make to MMI. I find the commonest ones to find yourself needing are carb, water pump, manifold, and exhaust flange.

THIS MIGHT WORK

Try PBblaster and tapping on the bolts for a week or so.
Then start the engine and let it come to operating temperature. While the engine is running go after the bolts. The heat + vibration will help loosen the bolts. I like a plain closed end wrench for this kind of work. I have a better feel for what is happening. A hammer on the end of the wrench is effective. Be mindful of carbon monoxide while doing this.

If the manifold needs come off you can hold it in place by using a tire. Jack up a corner of your vehicle, place the part under the tire, shore up with wood as necessary, then let the jack down so the part is held in place.

Good luck.

I was not smart enough to order the gasket with other parts. It came to my mind only on the following day. Now it's 45 bucks shipping cost (Canada) for 8 dollar gasket. Indigo charged me only 15 bucks for FedEx 3 day shipping.

Take the flange to an auto parts store, ask the person behind the counter to take the flange and look in their gasket inventory to see if they have one that will work. Bet you will be able to find a correct gasket this way.

How about just putting the thing in an envelope for $0.50

I didn't think FedEx would ship much of ANYTHING ANYWHERE for $15, and certainly not across the border.

Do they do envelopes? I charge $20 on top of whatever the shipping is when I sell to Canada on eBay to make up for all the time I have to spend filling out forms by hand and then getting told it was the wrong form and doing it again

I will need a manifold gasket (not a flange gasket that I actually ordered) which is quite unique. I don't think I will be able to find it in a auto parts store.

That's what I was thinking about. I'll ask Moeyrs if they would be able to send it to me like that.

Indigo shipped me a crank case kit (almost 1 lb) for 15 USD via FedEx. I had to pay sales tax on top of it but I would have to do that with any carrier.
