tortron Posted October 26, 2015 Share Posted October 26, 2015 Float level wrong 3 Quote Link to comment Share on other sites More sharing options...
azzurro Posted October 26, 2015 Share Posted October 26, 2015 ^concur - that hole is for air in only. use a 7mm drill bit and set it so the float just touches the needle valve without pushing the spring/ball thing in Ive got a manometer for balancing these too. I need a favour from Chris - you are just round the corner right? 1 Quote Link to comment Share on other sites More sharing options...
pusherman Posted October 26, 2015 Author Share Posted October 26, 2015 Ok will have to look into this i measured both buuut clearly fucked that up. Manometer would be le tit dude i have always done it but ear/eye can get it pretty damn close. Im in whangaparoa dude but pop round to chrisytaras from time to time.

azzurro Posted October 26, 2015 Share Posted October 26, 2015 the fuel coming out of that point is because the bowl is overflowing so could also be the needle valve not closing/sealing for some other reason if the float height is good. (fuel pressure not too high?) i thought you were from the hood (hes your pusher) moved out of the hood for good, you blame me? I could take the long way scenic route home one evening (takapuna to muriwai) and have a tutu? Quote Link to comment Share on other sites More sharing options...
tortron Posted October 26, 2015 Share Posted October 26, 2015 could be the needle valve. Have a real good look at it when you reset the float. some new ones are made poorly/skew-wiff and out of round 1 Quote Link to comment Share on other sites More sharing options...
NickJ Posted October 27, 2015 Share Posted October 27, 2015 ^^^ i've had issues with the same thing, even new ones sometimes don't seal, pretty rough but fine wet and dry with the needle in the drill fixed that issue. Also I've twisted the float while setting the depth in a hurry enough to clash with the side and jam open. Quote Link to comment Share on other sites More sharing options...
JoKer Posted October 27, 2015 Share Posted October 27, 2015 if you sort it out let us know please, these things seem to be a kind of magic all of their own & *knocks on wood* havnt had issues with mine yet Quote Link to comment Share on other sites More sharing options...

I would lap them together like an engine valve Quote Link to comment Share on other sites More sharing options...
azzurro Posted October 27, 2015 Share Posted October 27, 2015 or next time, splash out a few bucks extra for the ?viton? tipped ones? (i proably have a few spare old needle valves in my takle box of dellorto carb bits if that is the issue) agree that selection of parts for odd/old carbs is pretty limited and you have to take whatever you can get, but dellorto and weber sideys are pretty well covered for bits and they are 'high performance parts'. (pretty sure ive got brass ones in mine) Quote Link to comment Share on other sites More sharing options...
pusherman Posted October 31, 2015 Author Share Posted October 31, 2015 Havent gotten back into garage yet. (2 businesses, 1 wife,1 baby, 2 lawns,2dogs, dozen ciders means no car time this weekend) I got rebuild kit from weber specs so would expect them to be of a good standard. Makes perfect sense tho. Moneys in needle valve thingy Quote Link to comment Share on other sites More sharing options...
