I have another one for you guys. Thanks for all the help so far.
The answer will probably be rebuild the carbs but I just want to double check its not another issue to. The motor was sitting for a while. My other motor fried a piston it was an old '78 140. So I had the motor that came with my boat '89 120 johnson VRO. I changed the lower unit fluid new pwr pack because I didn't have spark on two cylinder, compression good all around 120 +/- 3 little low but all about the same. I took the carbs apart and they looked good. They are plastic carbs. I just sprayed cleaner through all the jets, bowls, etc and didn't see any varnish. I put them back. I plugged up the oil line because my other motor was pre-mix so I figured I would just burn out the rest of the gas in the tank then drain and clean the tank and hook up the VRO. I would rather not have the tank on my floor being only 20'. The motor starts right up and it seemed to run good, it would miss every once in a while on the muffs at 1100 rpms and drop to 600 for a second or two like it was loosing a cylinder. I bought new plugs it had QL77JC4's in there. West marine only had the NGK's ($9 each ugh), put them in and ran it on the muffs for a little bit. Checked the plugs and #1 and #4 were fouled. Cleaned them and decided to see what happens in the water. Tied to the dock it would idle fine I forgot to look but I know it was less than 900 rpm's when in gear it was about 600. The vro alarm kept going off i'm not sure if this was limiting my rpm's. When I tried to take it for a spin, it would not go past 1100 rpm's if I pushed it higher it would stall out. I tried a few times and brought it back home. Got it on the muffs and flushed the engine, did a compression check and it was the same as usual. Checked spark with an inline tester and bulb was bright on all, pulled plugs and three were fouled it was dry not too oily. plugs were black.
Also the thermostats were not in stock so I took out the spring and vernatherm and figured it would just take longer to warm up.( I tried to test them and dropped the vernatherm in hot oil while I was checking the temp switches. They never opened ) I hope that isn't the cause. I will rebuild the carbs on Wednesday if the kits are in stock and get new thermostats.
I hope this enough info Thanks again.

That's criminal.
