Again you go down a similar path to me. When i stripped the carb i found that an oversize main jet had been fitted causing the bike to loose revs and become lumpy at 45 mph.(to much fuel)?
I then rebuilt carb with ALL new components but reverting back to factory settigs.   
Needle setting postion no 2 couting from the top.(REF Burslam) 
Main jet. 200

yes it drove me nuts as well

I had a similar problem with my starfire , poor and lumpy tick over. Abeit didnt cut out when revved.  My problem was the Pilot Air Galleries blocked.  and noting your comments on removing of pilot jet screw  , and bike stills runs suggests cloggged galleries .
check out youtube.

i must of cleaned my air galleries at least 5 times before i got the results of a good tickover. Hoping you will/have resovled your problems.

Hi guys. all comments noted and thanks
1.Wet sumping all ok  there (no excessive oil when sump plate removed today).
2. You tube bad starting .yes have watched  that and picked up on slipping  clutch. new clutch now fitted and yes a great improvement.
3. My starting procure. fuel tap on , good tickle ,3/4 kicks without ignition on , another tickle, ignition on, kick bike, fire up then dies.
4. Can i tickle again whilst bike is running prior to dying, no cannot get down to carb quick enough.

So i am thinking fuel related issue, will take of carb of yet again . carb has been  cleaned including air gallaries (sorted my idling problem at that time. All internals  renewed and reset to factory spec.

So close but so far away he says.

Hi all. i cant remember the position of the clip? I think its no 2 (factory set up) but some books quote 1 or 2 . And do you count from the bottom or top on the needle.
cheers. mike

Hi.all thanks for your input.

Valve clearances done, and suspected the plug yet again. Metal can filled with petrol and dropped the plug in , and lit the petrol. (as i have not got a blow torch.)

Results it starts  3rd or 4 th kick  albeit a little lumpy. i think we going in the right direct  . Final carb set up/new plug pending.
Trying not to get to excited as i have been down this path before

Hi all. hope all is well during lockdown.
My 1970 starfire has always been difficult to start to the point my kick start spring broke(over worked) .Have has some good results in recent weeks but now refuses to start.

Amal carb fitted cleaned and new jets/pilot screw/throttle slide etc. (Pilot gallaries clear)
New plug/condensor/ht lead/plug cap
Have a good spark and petrol getting through.
I did  replace the clutch /springs as i thought it was slipping whilst trying the start the bike.I Left the points assembly in the casing so i didnt disturb the timing. i did check the timing a few weeks ago (when it was running) using a strobe . all ok

The only thing i have not checked is the valve clearances of which i will check out soon.

Back to basics they say, but i have done this so many times now. what am i missing? Hoping you can help me out, getting fed.
 up now .

bfn mike
stay safe
