So, the 1915 goes together tomorrow. I currently have a weber 40. Any recommendations for jets so I don't run too lean at startup. Or are ya'll running the same size jets?
Thanks, Don

Jetting for 1915 upgrade
Re: Jetting for 1915 upgrade
Hey,
I am about in the same situation as you and I have no actual knowledge for this issue. I run a 44 Weber with some custom 28mm venturis. I know that I will have to increase the venturi size because of the additional air volume. I am going to check my Weber info and sites today and I will update you if I find anything.

If you will send me your email info I will send the scan to you. Looks like I would have to post it to a website to be able to post it and I really don't have the time to that...

Okay, here's the skinny for your 40IDF:
1835-2000cc 30mm venturi, 1.55 main gas, 1.60 main A/C, F11 E/Tube, .70 idle, .75 p/jet...
It's just a base line and doesn't take into compression ratio, head flow, and cam specifics.. I would think that the main gas could be bumped some.
