New to this type 3 thing, always been a 2 man. However the lucky purchaser of peru67 fast back. Thinking of replacing stock carbs, got loose spindles (but not that bad) were re-jetted with NOS kit, linkages all ok. timing checked, valves checked, 009 fitted, only 1000 miles on engine, carefull driver never take it over 3200rpm.
Current problem whenever some ones tinkers with them car runs ok, but gets 'spluttery' uneven. Usual guy has them idling at 1000rpm says it runs better.options:
1. Anyone know garage in S. London / London area that know whay they're doing re: tune up carbs.
2. Woth buying these air flow things and doing it that way
3. Purchasing new set of Webber etc. (the expensive option, is it worth it?
4. Get a good 'real' carb rebuild?
5. Anyone in London area wanna meet up and advice.
If new carbs goy aWestphalia awning to sell if anyone interested.
Them carbs!!
Spluttery engine
Welcome to sanity, Iain!
Chuck away the 009. It was originally used in a constant speed running in a stationary engine, with centrifugal advance only. It was favoured by racer types who do run their engines in one narrow rev range - flat out!
It isn't flexible for normal road use where you don't want to slam it into low gear to get the last gasp of acceleration, and doesn't have the improved fuel consumption that vacuum advance brings.
I expect most twin carbs have some air-leaks at the throttle bushes - Laurie (someone) will rebuild them but it's about £100 a carb. He might just do the throttle plate I suppose. He's at most of the showws, and knows what he's doing. Maybe advertises in the mags too.
Don't bother with Webbers - very hard to set up to work properly; never work straight out of the box. I once saw a Type 2 with them - never seen so much soot over the back bumper.
The carbalancer is good - there are other ways. Check out the info in the Workshop forum here - I've set out how I do my stock twin carbs.

Thanks for the info, I've always thought the same thng about 009, kept the vacum on the Type 2 because it needs the help. You've pretty much confirmed what I thought, though these twin carbs do keep you awake a night. Thanks for the, always admired these strange things but Type 3's are fantastic cars, the 'regal' range from volkswagen!
