I have some redline softmounts you can have for free if you want them. i would sort out your float level first, sounds like no fuel under load also use those spring washers when mounting(i learn't the hard way= broken ears are not much fun. Do you have a fuel pressure regulator, they don't like more than . I think 8-9 mm is the setting for the float level. Let me know about those softmounts. Rory

My specs are as follows:

Main - 190

Emulsion Tubes - F16

Air Corrector - 145

 

I forgot to write down the idle jet # but I want to say 50F8?? Doesn't really matter as it sounds like you've got that much sorted out.

[kiznook]

You say you have 165 main and 180 air...???

 

Main jet sits on top

Emulsion tube goes under

Air corrector is in the very bottom

 

I think you might have these numbers backward, in which case, based on my setup, your air correctors are too big. I want to say that 140/f14?/140 is recommended for L20

 

If my theory on your numbers is correct, you need to downsize your air correctors, and maybe increase your mains.

 

I guess the real question is if you're experiencing a too-rich, or too-lean situation.

so after reading the weber pages that DISLEXICDIME sent me we have come to the conclusion that this was tuned down to run on a l16:eek:

 

accoroding to the book i need a bigger choke and diffrent jets.

We got it close,close enough to race :).

 

so iam on the hunt to find some new jets and chokes.

now according to the book i should be running

180 air

195 main

40mm choke

 

 

so where does a guy find these before friday:lol:

 

but we got it close it quit spuddering we mixed up some new jets and old to get it put it pulls hard all the way to 7100:eek:

 

my mech says it has more
