85 Cutlass Supreme - Mulligan

No, all of the linkage is removed and the base separated from the rest of the carb. its bound up in the bushings.

You tear apart floatbowl yet?

 

[Algershick]

Yup, soaked and cleaned it out. It really didn't look bad, most of what was in there was dried/powdery. This thing hasn't had gas in it for quite some time.

Yeah worse thing for a carb is to sit for a long time with fuel lol

 

[Algershick]

At least visually, I don't see a single difference between the electronic and my '77 bases other than the plugs on the adustment screws that I'll have to cut out. Excellent!

Lay the main body to throttle plate gasket from tho older carb on the newer throttle plate

Here's my greasy, rusty, pig of a 77 Q-jet when I brough it home.


Here it is after a little elbow grease (and Pine Sol) was applied. I love this stuff, I've used it on aluminum cylinder heads with great success before.

The base plate is still soaking. I'm waiting for a HP rebuild kit from Cliff and a new piece of linkage before I can reassemble it.

Pine Sol, I will have to remember that. What was that carb off? Any reason you aren't trying the TBI? GM almost used the TBI on the 307, there is even 3 experimental Olds 307 swirl port manifolds out there. There is a knock sensor that is 307 specific, the 88 to 90 models used them.

Pine Sol softens hard carbon deposits like you wouldn't believe. My exhaust ports in those 5.3 heads were spotless after some scrubbing.

I think I'm still going to go TBI but I'm eager to drive the car some and get more familiar with the fuel injection swap. What I didn't mention earlier is I'm using a MS2 ecu that I'd like to feel more confident with.

I pulled the carb from a 350 in a 78 Cutlass. The part number says it's a 77 model used on 350/403. Cliff Ruggles shop felt it should run fine without major modification on the 307, their HP rebuild kit is on its way.

That's interesting Olds307 and 403, I hadn't heard about the TBI 307 exerimental engine. I believe I saw a port injection manifold used on a Cadillac at some point. Pretty cool stuff!
