Larry's engine is dismantled currently.
He has the blower from down-under. Got it before Moss' blower.
Both his and the Moss unit have a single HIF44, or similar SU.
No webers here.
Search the archives from last summer. He kept us up to date on
all his trials and tribulations. Great reading.
He did a ton of development, probably has one of every needle SU
ever made. :-)
Or his web site might have a lot of it. www.red4est.com. Click
on Jasmine.
