FLUSHING COOLING SYSTEM

[Toehead]

IIRC you can: The coolant tubes just pull straight out

Problem is the installation. If that ORing rolls when you are putting the tube back in you can not see it good with the carbs in place.

I guess that I might as well just pull the carbs and replace all O rings and what ever I find.

When you put the O rings on the tube, lube with a bit of washing up liquid, and push the tube in as straight as you can with a twisting action, keeping an eye on the O ring so it doesn't snag. Hard to explain better than that, but it is obvious when it is correct. Make sure the tubes are pushed fully home. I did mine on the bench and then fitted the complete assy to the engine, think it may be possible with the carbs in place, but obviously less space to work in.

Better yet, go to the hardware store and get a small tube of faucet grease. It's made for the job and you only want to do it once.

Or a small amount of Vasoline applied where the tube enters,not on the O-ring. If you go the faucet grease route,buy a 3/4" fitting brush to clean the area where the tube goes in.
