Wow a lot to take in. Thanks guys.

As for the carb. Both the 650 and 850 are marine Holley 4011 series. They both have the J tube's, as well as vacuum hookup's at the base and above t-plates(ones plugged). Both are also electric choke. Have a flame arrestor(feel like it's choking motor, it's small).

After the motor rebuild, figured stock carb was to small. I had Holley run the numbers. They verified the above mentioned. I then found my 850 on Craigslist. Had Holley run the number for it. It was an 850, but used the same rebuild kit as the 650. Again they verified the above mentioned. Really the two carbs appear identical. I was upset, I probably could have just upgraded jets.

The original dist didnt have a vacuum advance. The motor installer upgraded the dist. The new one does have advance, but just capped it off. That would be the only thing that's likely not marine.

I didn't wanna get into the motor to much. I was just hoping it would be an easy switch over. Seems that's not gonna be the case. Its hard to check the TDC, because of a water impeller mounted to the crank pulley. I have to key bump. I cant move crank by hand. Plus I've been working on it by myself. It's gonna cost me to get the installer back. He's thinks it was good to go. Obviously not the case.
