Title: Gauze in idle jet?
Post by: Simon46 on May 18, 2018, 10:51:27 PM

Finally had to pull carbs on my 78 as it will only run on choke and no idle. Pulled slow/ idle jets from carbs all blocked. Boiled, vinegar, lemon juice syringed now blow thru. Found a gauze filter in one of them. Not checked other 3. Is this normal?

All late carbs have a little gauze filter  ;)

Hello Simon.
Yes my F1 had filters hidden away above the inlet needle valves.

Yep my F1 had the little filters in the inlet valves and they were all clogged, but no filters on the jets.

Cheers

One of the jets I can't see daylight thru again. Really want to press gauze out as it was fine 2 days ago. Aaargh
