SVDA, the problem started when i got some '****' in the carb, (california sand?) but just would not idle after that ran fine before. Anyhow I fitted a Filterking but try as i might i could not clean the carb, everything works fine choke, cutoff just setting it up was impossible, I have stuck another brocar carb and it's now running again. The other carb was a OG one but it must have some **** stuck in one of the airways which i can't get at, I though about sticking it in a bucket of carb cleaner but i don't think it would guarantee to remove the offending piece of detritus. Any thoughts to how to make the carb clean?
