John E Posted November 10, 2001 Share Posted November 10, 2001 Noticed in the garage today that there was some occasional spitting from the area where the 40's are fixed to the inlet manifold. Just a fine mist on both carbs. Never noticed this before. Does it mean that the o rings need replacing or that the carbs need tightening. Its a 1700 x flow.

Asklepios Posted November 10, 2001 Share Posted November 10, 2001 John, If you have the alloy plate with `o`rings either side,one can get blown out with a spit back.Try resiting or replacing. Link to comment Share on other sites More sharing options...
stevefoster Posted November 10, 2001 Share Posted November 10, 2001 It sounds like the rings. The moulded in to one type are more reliable but will wear out eventually... I found out that they only do a 45 carb size one piece ring and this caused a reed effect sound from the air expanding and contacting again as it past that I could not live with and I went back to the old style with new rings. The sound was very loud and nasty! I have 45's now and they 45 rings work fine... Link to comment Share on other sites More sharing options...
Roger King Posted November 11, 2001 Share Posted November 11, 2001 John, This is quite common and is usually a result of slightly weak mixture. It can appear when the weather changes and may need nothing more than a slight tweak on the idle mixture screws. It usually gets better when the engine is up to full working temperature.

John E Posted November 11, 2001 Author Share Posted November 11, 2001 morning guys. I have to admit that this was on Friday when the outside temp dropped to just above freezing so I'll tweek them little screws and see what happens and yes it does go when the lump is upto temp.
