Mechanical Sympathy Posted October 12, 2013 Report Posted October 12, 2013 Have you tried adjusting the idle mixture screw? Is the choke fully open? Quote
inspiredrollaboy Posted October 12, 2013 Author Report Posted October 12, 2013 (edited) Yea i had the screw pretty much the whole way out still high and the choke is fully open Edited October 12, 2013 by inspiredrollaboy Quote
Boosted Posted October 16, 2013 Report Posted October 16, 2013 Winding the mixture screw out would increase revs. Are you sure you're playing with the mixture screw and not the idle stop ? Base setting for the idle screw should be 1.5-3 turns out from seated. Ignition timing will also affect idle speed. Why did you rebuild the carb, what were the symptoms before ? Quote

Boosted Posted October 16, 2013 Report Posted October 16, 2013 Timing seems fine ? or is fine ? If winding the mixture screw in/out makes no (or very little) difference to the idle speed, I'd suspect a leak or an assembly fault, particular if the engine falters once the load comes on. Quote
