[FONT=Trebuchet MS, Verdana, Tahoma, Arial]<!-- google_ad_section_start -->Hi Tim,

I had this problem with the stock carb (well, a 34DMTR actually) when autocrossing, but only in left turns I believe. The soulution was to lower the float level by 2 mm. This makes you car run a little leaner in general and you may have to change your jetting.

At last weekend's autocross, I discovered a similar problem, but in both left and right turns with my DCNFs.
Supposedly, fuel sloshes out of the float bowl vents and goes down the air correctors, flooding the engine. I could lower the float levels, but I think I rather try the snorkels, since the carbs are set up well otherwise.
All this involves is to find some tubing that has the right inner diamter to stick on the air correctors. A guy I talked to said he used plastic tubing that was a little too small and reamed it out slightly until it fits.

I will do this in the next couple of days and report back.

That should earn a few browny points,No pun intended, snigger snigger ;-)_
It's a 34 DMTR 87/250, getting back to the problem in hand, do you mean fitting a pipe to the air corrector feed holes visible from the top of the carb,the bit that sits on top of the emulsifyer, I would have thought the gasket would stop any fuel getting up this high?<!-- google_ad_section_end -->

[FONT=Trebuchet MS, Verdana, Tahoma, Arial]<!-- google_ad_section_start -->Tim,

if it is a DMTR, the solution is to lower the float level. I lowered mine 2mm from the setting specified in the manual and this fixed my problem.
The snokel idea was for dual carbs (DCNF).
