Hi, Looking for some inspiration here, have a500EN '90 with CVK34s starts runs to about 2krpm, then fuel starvation (?) choke hardly helps, carbs cleaned many times,all good, runs up about 1/4 throtthle then gasps and slowly dies, sparks all good checked with timing light, .float height 17mm , fuel level +.5.. over.base.. Manual says keep vent tube away from intake, upsets etmosphereic balance in float chambers, but no matter what|I do it's the same. Is this designed so that the air resistane in the factory airbok/element is so critical to mixture? ` am attempting to run individual cone cleaners. , getting adequate flow thru tap, . - like geoff boycott, I'm Stumped...... any ideas please?
Best Regards all Paul Milsom
