Re: Dellorto PHBH 26mm & 30mm ref
Hi there i have amended the delly ref section for people using and setting up Dellorto PHBH carbs on Lambrettas.

Re: Flow rate
I found i had to ditch the inline filter on my mugello with 28mm as it wasnt up to the job. As said above, a pint in under a min seems fine. Does it still flow at that rate when the tank is say a third full? I had issues when running low with flow rate, it was fine when full. With inline filter remo...

Re: delorto jeting
Roadrunner what exhaust are you running? Have you gone from airbox to ramair? You will need to re-jet if changing the air intake on an engine.
Have a look here for a few ballpark delly setups inc a 175 kit.

Re: Lambretta Port timings

Thats my main worry..Im going to put it together tonight and make test ...

Re: Lambretta Port timings
Im not too worried about gearing at this stage. Thats the next problem. My question is really about the port timings. It did easily pull a 46/15 before i opened the transfers etc so the 47/16 is not really a big jump but time will tell. I wil keep you posted on the gearing, i can always go to a 47/1...

Lambretta Port timings
Hi there just wonder if these seemed ok to use... Exhuast - 184 Transfers + Boost - 123 (trying to stagger the boost a tiny bit earlier, maybe?) Inlet - 163 This all on a Mugello 186 (58/107) Li150 block, opened tranfers and matched to head. Flowed as best I can. Anyone have any thoughts about what ...
