Choke seals leaking
Turbo Mini Forums

Choke seals are leaking fuel on my rebuild su, iv replace them twice with the correct new ones but still no joy, I bought another carb to see if I'd put it together ok and everything's ok it a hiff44 converted for turbo, it runs perfectly just leaks on boost, anyone have any ideas

Anyone

The last time I rebuilt a carb I found the choke O rings in the kit from burlen were actually too small, and would not have sealed if fitted. Are you sure the O rings are the correct size?

Have you checked fuel pressure,

Mine leaked when the choke was on and allways wet after but seams to of sorted itself out !

I've had this before. To be honest the choke seals that come in the kit are pretty crap. Sometimes they seem ok, but ive used some larger o rings from something else before.
I'd mention it to Burlen, especially if you've bought a second set. If enough people moan, perhaps they'll sort the issue.

Fuel pressures 4 psi when idling, it's a new pressure regulator,il try some bigger seals if that don't work burlen sell the choke assemberly for £60.

Try 3psi?

Had the same issue with mine years ago when I used a burlen rebuild kit, I put some thicker O rings in which sorted it.
Made my choke a lot stiffer but I never needed to use it and it didn't piss fuel out so I left it
