blueprinting a dellorto VHSH

[mickdale]

hello
got a new 30mm VHSH dellorto for a ts1

does it need "blueprinting" of the inlet above the float jet ie taking out the half moon hole to a full circle to stop any possible fuel starvation problems?

cheers

Never touched my one, and it's been on couple years now , and is held at pretty high speeds. Just make sure you have a 300/350 float valve.

thanks bazman
saves owing the driller in the machine shop at work a pint lol

the carb came with a 300 float - its what ive got in the PHBH coming off so should be ok

have you still got the plastic fuel filter tube under the inlet or have you removed it?

cheers

Found this if it helps anyone.

[bazman]

Yes have the 300 in mine and the filter, like i said no issues , and managed to get back to Annan first this weekend in a little ride out we had from Tynemouth ;-0)

thanks bazman

i wonder if the normal PHBH idle jets will work as the idle jet that came with the carb is really tall (looks like same thread etc)

[bazman]

Pretty sure they dont fella , there's actually 2 jets on the idle circut, normal looking one at the top and below a emulsion tube. I run a 60 top and b40 tube.

[mickdale]

the large one on the left is the 60 that came with the carb, the small one on the right is a PHBH one

[mickdale]

there is a tiny brass thing in the carb under the jet - is this the tube you mean

cheers

middle hole just above the atomiser but below and to the side of the choke jet

[bazman]

Yes that's the emulsion tube , very fine blade screwdriver will get it out , people have run without the larger jet before , but it acts as a funnel to supply the tube if you know what i mean?
