I thought to give Mustang's Mikuni carb cleaning sticky a whirl and follow some of his advice on settings etc. seeing as I had to take the carbs out to re-insert the manual idle screw. I had also missed the "hidden" filter first time I serviced the carbs for seized butterflys. At this time I did not touch the pilot needles with the philosophy of nothing has changed since it last ran, leave well enough alone. Maybe I should have because all the pilot needles had semi corroded in and were rather tight. The first one althouth tight seemed to turn in 1 and a quarter turns before getting stiffer. Number two was so tight I thought better of seeing how tight it would go and just loosenned it. Number 3 is seized in propper. The screw driver has basically malformed the slot and any further fettling will completely destroy the slot. Mmm 2 turns out then on that one is unlikely. Probably 1 and a quarter like the first. I seem to recall reading here somewhere that is the tad lean original factory setting. So it's a toss up now. Drill and run a real risk of catastrophy or leave as is and return the previous two to 1 and a quarter. (If indeed that is what they were....hard to be certain when they are that stiff)
Decisions, decisions ..... :(
Do the right thing, or do it again later. At least that's my experience. :lol:
I know......damn!
Ok, I am in the market for a carb set or cylinder no. 3 carb body. Mikuni.
I have drilled to the beginning of the thread but it's corroded in to the point of breaking all torque bits.
Ok at this point seeing how you are resigned to replacing the carb /carbs
try a little heat from a propane torch ..not enuff to melt the alum but enuff to get her good and hot and quite possibly the pilot needle will give up and let go
I hate to see other people's projects going sideways like mine always seem to. Sorry, brother, I feel your pain. 8)

Been there :( nothing. Less that 0.3 mm of the original left. Drilled to the needle. Cut into the thread on two sides to collapse the remains. This bastard has welded itself in. Typical of stainless in anaerobic conditions. Bugger. Best bet now is to drill over size and insert a tapped brass bush. But the engineering for that may cost more in the end. Absolutely gutted.
whats the thread size on the pilot screw ?
Lets see a pic Bruce..... wish I was closer so I could come over & help ya...
Hi Bruken. PM'd you

I dont have a thread guage but with vernier it looks to be 0.6mm

That's kind of ya Geoff. I hate calling a buddy when a job has 95% chance of going south. They come in feeling like a hero and leave feeling worse than me :lol:

Your advice was sterling :lol: I had a running Tiger and a fuberized it. Aren't you the prophet of doom? I blame myself. Ja hey. Enthusiastic amateur...that's me :shock:

mmm, My reply pm is lurking in my outbox. If you dont get it, let me know, but my answer is yes please.
Pm'd you too but its stuck in outbox....So have you drilled out the jet from that hole Bruce???
No Geoff. The needle sits on the end of a threaded bolt. I have drilled that portion of the bolt out so I can pull the needle, spring etc out. what remains of the bolt is 0.3 mm of remaining wall before the thread. Normally you can collapse this and remove it by cutting one, maybe two sides of the wall. But it is not budging. I could have a threaded brass insert made to go in an oversize hole, or could get a tap and cut the last portion of wall out but this is problematic as the needle shoulder won't allow a full tap. But in the end, the tolerance factor is so tight, any repair really would be time wasted. Better to replace the carb body. Ya know, you got to try anyway, sometimes you loose. I may have a hero tho :)
Look at the larger diameter threaded hole. You look closely enough you will see the remaining wall darker grey I.e no thread...because it is still the remains of the needle threaded shoulder / bolt section
Am I making sense? I don't understand my own explanation.
Ok I got it now.... :roll: well hopefully you might have got sorted... if not let me know, see if I can help....
:P
MIMbox has sorted me out a replacement carby set at a fantastic price especially when considering their cost to replace new. Dealer won't sell just a body, got to buy a complete set. I am chuffed to bits I am, I thought at the time, "here we go, can't make the distance, yer screwed" and not 24 hours go by and I have a promised replacement. How cool is that? This site is a godsend. So whoever owns it, I could kiss you (hope you are pretty in case you take me up on the offer)
Thank you MIMbox :friday :hello2
Abruzzi owns it
But I doubt Geoff wants to kiss yer mug :ImaPoser
Even better :D Its my lucky week !
My replacement carby's arrived today
Thanks MIMbox :occasion14 :eusa_dance
