hi guys if twin 45s have been done up tight ie squashed thackery washers does it really make any difference ie does fuel really froth up............cheers in advance

Cant you just slacken them off?, they are made of springsteel so should open back up.
they are there for a reason new ones wont cost the earth.
you should be able to rock the carbs up and down a little when set up correctly.

It is not recomended by Weber to run DCOE's without some sort of rubber mount due to the problem of a weak mixture being induced by fuel frothing.
I would suggest that you remove the thackery washers and the sandwich plate and replace them with a Misab kit. Worth every penny.

just wondered if it does make any difference because if too loose i thought you lost vacuum but this is only from reading...........

It is not worth taking a chance on the thackery washers. I havnt used these for years, so the chances are these could be 20 years old. The Misab kit is cheaper than an engine rebuild and would take a few hours to fit against a few days to do an engine.
If you are in any doupt, change them.

thank you "atspeed racing" a shall order a set............its a shame i'am not closer to you or i could have booked in for a tune up...........cheers

"misab kit" only seams to be £20 is that too cheap ?

That is to dear. We charge £15.00 plus the VAT.
This is a complete kit and woulds do a pair of webers or Dellortos.
