Hey Kirk,

Are you referring to the small pee tube under the tank? ?There probably hasn’t been a line attached to it in decades (if ever), but I don’t smell any fuel or see any fuel stains below it or on the motor etc. ?If there’s an overflow on the Del’s it’s new to me but I’m more familiar w Bings.?

?

It’s been topped off a few times and no losses are evident.?

?

Thanks?

Losing no fuel via the overflow??

Best regards, Kirk

Thank you Mac, so you adjusted the float bowls to a higher fuel consumption level and it helped at higher speeds? ?Sounds like an issue I had with Bings many years ago, but not as familiar with the Delortos. ?

Had same symptoms. Although float bowl levels seemed ok, ?I gradually increased the fuel level until the prob went away.?

At first it ran fine at Hwy speeds, but then went into stumble mode.?

Fuel starvation.?

Happy New Year All,?

So I’m going to do my best to describe an issue I’m having (and have been troubleshooting with my trusted mechanic) to get opinions, which may help in the process of elimination.

At highway passing/overtake speeds I get a hesitation or hiccup type problem, usually above 55 mph, also sometimes feel starved at idle at stops, which seems to get worse the longer the engine is running.? Strangely, it’s feels quite powerful and runs great around town though.

Transmission & clutch fully rebuilt, plug gaps, timing (with EME electronic ignition), and Delorto’s balanced and needles checked, all new fuel lines also checked, compression is fine too.? ?

Advice really appreciated if you have any, cheers!

Chris
