Hi Guys , sorry it's another Amal prob! Just fitted 2 new amal 932's to my bike along with a Tri-spark,. Tried to start the bike and it was all over the place , Ok new carbs, so I can accept a bit of tuning is required. First thing was, my carbs wouldn't flood on the tickler so I did as suggested in the forum and removed the tickler and extended it slightly, they now flood on demand, then I set the float height 1-2mm below flange, bowl in the normal position. I then checked the slide opening using 1/4" rods and made sure they were opening at the same time. The bike is running but not too well, I even got a slight kick-back at one time.
I have then put my Davida vacuum gauges on and adjusted the carbs from there, I was getting an occasional backfire from the r/h pipe but that disappeared when I adjusted the pilot screw. I can get the bike ticking over with the vacuum gauges reading very nearly the same, one of the needles on the gauge is fluctuating a bit while the other is near enough rock steady. Also one of my pilot screws is out just about 3/4 turn and the other nearly 1 1/2 turns, is this acceptable?, also find I am having to tickle the carbs to make it start. Tri -Spark set to 28 btc.
Any help would be appreciated

Thanks
Robert
 
Re-check your valve adjustment, strobe time the ignition, then fiddle with the carbs.

Some of the new Amals have been found to have casting issues resulting in stray bits clogging or altering flow through the drilled passages.
 
Sounds like the pilots are suffering from swarf as GP says, a squirt of carb cleaner should do it but be prepared for potential for a piece of swarf to be dislodged by the carb cleaner but stay around for a repeat performance :shock: .

Did that earlier, gave them a full blast through, Just put a colourtune on both carbs, showing blue, spitting gone, (the bike's not mine!), decent tickover,so here's hoping, still needed to give a wee bit of a press on the tickler though! I'll let it cool down a bit and try again later. Can't take it on the road for a test run as it's not MOT'd, so once I get it good enough I'll book a test, then do the neccessary on the other circuits.
