As mentioned previously, the bottom of the jet/choke mechanism under both carbs is getting wet with fuel. Signs that my recent work on the Float Chambers hasn't hindered fuel flow..? Also, I can see signs of fuel in the carb body and on the Throttle Disc, and I also noticed fuel dripping from the vacuum advance pipe connection under the front carb today - after much cranking over attempting to start. Is this all signs of too much fuel.!?

...that sounds like a plan!

Hi Rob/All Update: Started the engine this afternoon with the now familiar 5-10 seconds of runtime before it faded away and stopped! I immediately checked the fuel level in the Float Chambers and both still had fuel in them - to approx the same level as before starting ...so I'm assuming the fuel pump is OK, and the Grose Jets. I removed the Chamber and Piston of both carbs; the fuel level in the jet you describe above - Is that in the small hole the Needle sits in? I couldn't see into the hole to gauge the fuel level - far too small or my aging eyesight! It certainly wasn't full.!!

Hi Rob Whilst I had the tops off the float chambers I did check the setting of the levers (129) as per the manual - I had to raise (bend) both levers (one more than the other) but this will have increased the amount of fuel in the chambers before the valve is closed by the rising float. I have got the Grose Jets as opposed to the standard Needles & Seats - I changed these last year (Has it run properly since - I can't remember!?). I haven't checked the float chambers after the short run so that is worth looking at - I'll do this tomorrow... There is definitely fuel getting to the

Afternoon All So... I've made good progress and resolved the problem posted above. In dismantling everything and removing the stud (123) I discovered that a PO had put the studs in without the fibre washers (124) and with something that could have been PTFE tape on the thread! Giving everything a good clean, fitting new fibre washers and seals (118) has resolved the leak. I couldn't find any info on how tight to do up the nut (120) - I didn't want to over tighten and deform the rubber washers - but in the end I did everything up pretty tight! Sorted..! I now have a different problem

Hi All, I'm after a bit of advice if I may... I'm having to replace the seals on the bottom of the carbs, where the float chamber attaches. I have the arrangement on the right in the image - Stud (123) and the nut (120). New seals received from Moss... Questions is: How tight should the nut be done up? After a long time standing idle (The TR, not me!), on trying to start it over the weekend, discovered fuel leaks from both carbs and the nuts weren't tight ...tightening them didn't stop the leaks and could almost have made them worse! Many thanks in advance Nick
