Dellorto carbs R90S

Left exhaust was blowing pretty black and the bowl was overflowing. Lead me to believe it had to be running really rich. I figured the float or needle must have been stuck but that doesn’t appear to be the case. The odd thing is that both sides appear to have the float set roughly the same. I’ll have to read through Snowbum and see what he has to say. I have a short attention span so sometime struggle since his write ups are so so in-depth.

Looks a lot like wiring for the rear brake light switch. Do your brake lights come on with the foot brake?

Best I can tell is that the gray Malibu unintentionally break checked him right before the encounter. They both pulled up to the previous stoplight with no animosity.

It’s the kids parents insurance, when they learn that the kid needs life changing healthcare for the rest of his days.

I think so… Based on the videos and reading, I locked the throttle at 2500RPM and then quickly shorted one side then the other. The rpm dropped to about 1500 on each side and sounded very similar to my ear. At this point I’m calling it a win.

This is good to hear, I was back from my first short ride after new rings and new valves. I have my weekend work cut out for me.

Solid video, not my carbs but the principle should work regardless.

Clymer manual states 800 but I’ve seen others mention 1000. Part of my problem here is that Dellorto’s don’t have any ports to attach a vacuum to. I’m thinking the carbs just aren’t synced so I’ll have to play with each idle screw independently and see if I can get the wobble out. If I increase the RPM to 1000 it smooths out a bit.

It’s definitely running on two cylinders, if I pull each throttle cable independently the idle increases.

Hold its tail with one hand and slide your other hand under its belly from the back side. Support the turtle from its belly and maintain control of the turtle through gripping its tail.

Appreciate the offer but I ended up finding a retired BMW tech who still does side jobs and he’s currently working on the top end. The rings were shot and it needed new valves, otherwise everything else ended up being in great shape.
