CB125 Superdream - Pilot Screw

[richjp]

Hi all

As reported in a separate thread a week or so ago, I have been trying to get my rebuilt engine started again after a couple of years sitting. The electrics are all fine, turns over nicely, with puffs of exhaust coming out, but doesn't catch.

Sparks look good (white, not blue - is that an issue?), fuel flowing OK from tank, so I decided to strip carburettors again to see if anything was blocked. All looks OK. However, I have a question on the pilot screws - the manual says screw in fully and then screw out by 1.25 turns. When it says '1 turn', is that the screw head going through 360 degrees, or 180? If I take the latter, I get the head of the pilot jet appearing as shown in the attached picture. If I a assume 360 degrees = 1 turn, then the head of the pilot jet is barely visible above the inner face of the carb.

360.

You need to replace that O ring seal.

360 Deg... Five 1/4 turns.

You didn't read the question did you, Fisty?, that's two answers to two questions; but hey; if it another opportunity to waste band width contributing nothing of relevance, but makes you feel superior, being able to point out apparent error, rather than offering actual answer to OP... carry on... the irony in the 'waste of bandwidth' comments to my rambling posts is quite delicious.

All made sense to me, one turn is 360 deg, he needs to screw the screw out 5 quarter turns. Could have been made clearer in Mr Mike's post but it was right though?

You need to turn it 450 deg or 2.5 1/2 turns.

So to clarify, How Mike should have communicated his point for the greatest accuracy and least confusion:

"360 Degrees, so that will be five 1/4 turns from the current position."

Tef should not have mentioned the 360 bit at all, just said:

"Screw out by 1.25 turns means five 1/4 turns"
