Sh2/22 problem.

[Ihateyoubutler]

I have to have the mixture screw set about three and a half turns out to get a decent tickover.It's too weak screwed in any more. Idle jet is a 50 (tried a couple) and can't find any blockages in the carb.Manifold gasket appears ok and the carb is tight on the manifold. Engine is a 200 indian barrel with ports only tidied up and a taffspeed exhaust.
Any ideas what to try?
(Apologise if in the wrong section).
Thanks.

Is the carb off a 200 motor originally or a 150 motor?
The slide's are different in the 200 compared to the 150.
That could be your problem.

or if its a jetex carb change the pilot jet for a genuine dellorto

If its a jetex its an airscrew and screwing out will weaken so prob not that

The carb's off a 200 and it's a dellorto.Internals seem correct.Slide has a bit of wear. Are pilot jets bigger than 50 available?
Thanks.

Thanks for the help.

Be sure your air mix screw is of the longer variety which is correct for the 22mm carbs.
