No orfice or restrictor needed just pinch and open a little check readjust till it stays in tube 3/16" fish tank air tube then fine tune. I use 25' of hose so doubled and a 7' drop gives a bit of time B4 it gets sucked in. Tips on flow valve may not be bad they can stand alot of diff type stuff. I found the carb cleaner and air blown thru the carb ports after tear down works just fine!Never soaked em.

I am not sure if it would have worked just blowing through the ports. There was really a lot of stuff on the bottom of the bowl!
I might try the PO synchronizing tool later and use it to fine tune the carbs. But right now I just wanna put the bike back on the road!

guys, that piece of crap does not work. The idle always fluctuates

I assume your talking about the Morgan Carb Tune? I bought one earlier this year based on the feedback on this board and couldn't be happier. Way better setup than the mercury manometers that I used to use in the shop 30 years ago. Mine works really slick.

Did you cut the hoses approx 6" and install the little dampers? Without them the Carbtune will bounce like crazy.

It sound like your idle problem may be an air leak. Make sure you can get a steady idle before you install the carbtune, and if you can't, start looking for an air leak.

I did look for an air leak with a smal hand held torch. I might try bringing it to my freind's garage. he's got a gas welding thingie and I think that's one of the best things to check for air leaks.
It's the carbtune I have yes.
Man it's the third time in a week I am rechcking valves and they are ok.

I cut 90 cm ,put the dampers and then put the other 10 cm of tubing.
I just have to wait for the torn diaphragm now. I am still not sure if it was like that which is very unlikely or I did tear it

OK I put everything back together yesterday and did a 30 km run with it. After riding for 10 minutes idle seems fine. No more backfires. I think it's just that it takes a loooot of time for the engine to warm up. Might change the pilot jets as was suggested on another forum for 1 size bigger
