Wessie34 Posted July 19, 2017 Share Posted July 19, 2017 I have an '86 tk carb on a later bike but can't find float height for it. It seems to be above the float bowl to main body seal ! It therefore leaks and I'm going to change the seal next week . I'd just like confirmation that the level can sometimes be above the gasket, I've never come across that before. Thanks in advance, Dave ps. I'm going to put a small washer under the needle to richen it rather than changing the jets. Link to comment Share on other sites More sharing options...
Moderator Cynic Posted July 19, 2017 Moderator Share Posted July 19, 2017 Firstly the gasket should not leak. When your riding the fuel will swill around in there and the seal should be sound. Ball park float height. Should see the main jet submersed in fuel by about the depth of the jet (ish). Some carbs like the mikuni's on early dt's are quite sensitive to it so go with caution.

Wessie34 Posted July 19, 2017 Author Share Posted July 19, 2017 Thanks, great tip regarding using the jet depth as a guide, I've never heard of that. Cheers Link to comment Share on other sites More sharing options...
Moderator Cynic Posted July 19, 2017 Moderator Share Posted July 19, 2017 It needs to be in the fuel to suck it up. Normally you would go with a float height not a fluid level, although some are measured using the drain on the float bowl and clear tube to see where the fuel actually is, and obviously it cannot go higher than the floats can go as a maximum.

Wessie34 Posted July 20, 2017 Author Share Posted July 20, 2017 Thanks for your help, I'm waiting for the new seal and then I'll do some fuel level / height checks once it's off. Dave 1 Link to comment Share on other sites More sharing options...

Wessie34 Posted July 30, 2017 Author Share Posted July 30, 2017 Tried google again, but this time drilled down into the results further and well, the Haynes manual is right, both the cv and teikei carbs use the same fuel level ( 11-12 mm below carb body interface) although the manual doesn't mention the xt having a slide carb in 86-87! so ive lowered the fuel level to 12 mm , raised the needle one notch to richen it slightly and all is well. 1 Link to comment Share on other sites More sharing options...
