Hey guys just wondering what do you use to clean the Erude/Johnny plastic carbs of the 90's? I have no experience cleaning up these plastic guys. Will regular carb cleaner eat up the plastic?

I just did all mine and when asking the dealer they suggested engine tune. Apparently the automotive stuff could be too harsh, or so i was told.

Use OMC Engine Tuner. You can put the carbs in a bucket of that and happen to forget it and the carbs will still be okay. Been there. Plus it cleans real good.

I used a regular carb cleaner, but sprayed the carb parts with a WD-40-like product to remove the solvent, after she was clean.

Thanks guys. Boobie I will get some BRP next time Im at the Erude dealer. I ended up using sea foam spray, which is a petroleum base and is safe on plastic. Blew them clean with compressed air and then dried them off real good. Didnt seem to alter the plastic at all, and did a good job cleaning up all the jets.

I have really mixed feelings about plastic carbs in the first place. My neighbor has a plastic topped carb on his OB engine and he broke it. And the cost to replace a "plastic" top on that carb is ridiculous to say the least... You would think that plastic parts would be so easy to manufacture that their cost would be miniscule. But that's not the truth. Those plastic parts warp, break, snap off and their cost are more then an entire metal carb... Maybe cheap to make initially, but certainly not cheap to purchase replacement parts... JMHO!

I agree completely, but since the motor itself is in great shape, it is just something that I have to deal with at this point.

Boobie, do you happen to know the torque specs on these plastic carbs? I just snugged them up for now but need to figure out the proper specs. I have a factory service manual on the way. 1995 E-rude 130HP

Proprietary parts from a now defunct manufacturer that has been out of production for over 15 years....plastic or metal, you're going to bend over either way

dingbat you are absolutely correct. In my neighbor's situation, after really looking at his plastic top carb plate, it would seem pretty easy to mill an aluminum replacement if it were mine... But folks without that capability, you better look for a replacement type carb and work out the linkages because that plate was in the hundreds of dollars IF you could even find one...

Lots of used carbs parts from that vintage on the market if you know where to look.

Sutor. Float bowl screws 18-24 inch pds. Carb to manifold 45-55 inch pds. When installing screws for the float bowls back them off until they click and then screw them in. You are then using the same thread they came out of.
