<DIV>Before you all leap out and spend a bunch of money on an OS pump for your
OS 1.60 here is what I found out while experimenting with the OS
1.60's.</DIV>
<DIV> </DIV>
<DIV>First of all, you cannot buy the pump separately. It comes installed on the
1.40 back plate.approx $150.</DIV>
<DIV> </DIV>
<DIV>Secondly, the standard OS 1.60 carb did not like the OS pump anywhere near
as much as it liked the Cline regulator. (Other 1.60 users swear by the Perry).
Either way the OS pump produced too much fuel for the OS 1.60 carb.</DIV>
<DIV> </DIV>
<DIV>I spent a lot of time working on the pump in the backplate with the
std carb. Tried twin pug heads etc. Still could not get a good transition. If I
leaned the pump for a good transition then the engine would go lean
in the verticals. I finally had enough of this and went to the OS mix carb (the
one that is sadly not available). </DIV>
<DIV> </DIV>
<DIV>You, (or at least I, could not) cannot get the std carb to work well
with a pipe when the fuel is supplied from an OS 1.40 pump. I did get it to
work well with a 1.40 RX carb. This carb is designed for the pump but needs to
be drilled and tapped to take 3.5-mm screws to hold it in place.</DIV>
<DIV> </DIV>
<DIV>The Cline will get you much better results for around $40. (Or Perry if you
prefer) and you can use your existing.</DIV>
<DIV> </DIV>
<DIV>Regards,</DIV>
<DIV> </DIV>
<DIV>Eric.</DIV>

size=3>Yes, he does make them available to those that want them. They are
machined from billet stock, you will however have to supply your own pump. I
think Tower has them at a reasonable price? There are no carby mods
neccessary. I have mentioned this about two years ago, maybe thats where Eric
got the idea? </FONT></SPAN></DIV>

that works out about 75 US. Not cheap-but speaking as a YS man-even I have to
say his set up is sweet.</FONT></SPAN></DIV>
