Weber Carb Dieseling

Hey everyone,

Thanks for all the help so far and sorry for all the questions. After all the troubles with the factory carb I've just replaced it with a Weber 32/36 - bought the proper kit and made sure its genuine/made in Spain. The 4G63 has never run so well, honestly can't believe the difference in it. I went down the route as other members on here and am using an electric pump putting out 3-4psi as recommended. But despite how well it now goes, its dieseling really really badly - I've been doing some homework and wondering if I need to seafoam the engine in case of carbon build up? Is there anything else I can or should be doing before going down that route?

Any and all help much appreciated, cheers!

Try adjusting the idle speed so it's on the low side - 650-700 rpm or less based on what you and the engine can tolerate. Also check that the primary throttle is closing at idle. If not, add a little more slack in the accelerator cable. If still not closing, you may need to fashion a second coil return spring.
Lastly, check that the idle mixture and timing are to spec.
Which Weber did you install? The DGEV or DFEV?
