weber 28/36
Turbo Mini Forums

hi guys this is not for me really but for a friend he has a 998 A- and has rebuilt a weber 28/36 new gaskets new jets ect but when he came to fit it he couldnt get the car to tick over it would rev but when let go of the throttle it would die restart car and sounds really lumpy then die unless throttle was opend. before he was using a 1.3/4" su and his car ran great any ideas? i thought maybe not enough fuel to the carb

Done now needs redoing lol

this may be over jetted, for a big bore race engine, does he know the history ?

the 998 wont make any more power with the webber fitted onl sound like it does

i suggest he replaces the original carb which is more than up to the job

do a search on googel to see which jets he requires to place him in the ball park with his engine spec if any ?

hope this helps

Wasn't the 28/36 a bit of an economy carb? in which case its not much use against the SU anyways.

cheers guys it is jetted to a tuned 998 according to the holy bible vizard book but i shall advise him to use the su

Done now needs redoing lol

I ran one for a while - it was lovely and smooth on a 998 or 1150 but was jetted for a 1380 and drank fuel like there was no tomorrow.

If you can spend the time & money to get it jetted right on the rollers it will make for a nice carb.
There is a section in the Bible on how to adjust the idle.
