Well changed my timing, ran out a tank of 93 and replaced it with 89, still has a hicup but not as many... Gotta order new jets and float pan gasket...
Hope you got yours fixed DT.... How was your gasket mount?

REW, I havent had a chance to even loosen one bolt! I have a new born baby that's taking any free time I have right now. Its kind of a good thing because its allowing me to get more tools and things I may need. I also purchased an intake wrench (KASTAR 5530). Should cut my removal and install time in half. Now Im wondering what the best grease to use on my gaskets would be, I hear good things about lithium based but some people say the copper seal spray works good too. Im gona go ahead and clean the hell out of my carb and jets while its off too. Im hoping to maybe get started on it by this weekend

DT...Texas was right in my case, took more time than I did before and hit the Manifold seal with spray and there it was, top of the seal. Don't think I really hit it the other day hit mostly sides and bottom since it was more accessible.
Hopefully a shop will have one Tomorrow?
Hope this is my fix and yours too easier to do..

Ill give that a try as well before I start dismantling everything. I only hit the top of the manifold with a ton of spray the first time. Ill have to take my time and really narrow it down

Spraying windex (or, better, soapy water) is to detect a leak coming out, like an exhaust leak; it makes bubbles, just like a tire leak. Vacuum leaks, the more likely cause of your problem, require something combustible, so it changes the mixture. If you know you have an intake leak, fix that before you waste any more time.

The windex will probably smoke and burn, but the only thing that's diagnostic of is the fact that those things are hot. Buddy must've been thinking of tire leaks, but even then windex doesn't really have enough sudsy stuff to work well for that. It sorta works.
I don't think it would hurt much but I wouldn't be spraying a bunch of soap around there. Soap that doesn't get rinsed off leaves behind sticky soap concentrate that just attracts more dirt and contaminants.
There is an aerosol spray made to help start engines, forget the name but that would be ideal. Next would be to waft propane from a small torch at it. Safer and no residue but hard to get a positive result because it really has to be wafted in there, whereas the sprays can sorta be pushed into the test location.

I believe it was the product linked below. I don't know if that has ether in it but that's what I used a few years ago on a Yamaha. Thanks for pointing that out, I had no idea it wasn't suitable. This was quite a while ago, and it made sense to me at the time since it's intended to be sprayed into an intake. But now that you say that, in one case the engine is cold and not running, and in the other it's the opposite of that.

Question for someone... The leak is at the top of the seal, kind of like the carburetor was in at a angle? And it should have been.
Is the a way to make sure it levels up in the seal? Now I wondering if the air intake bracket is bent?
