Bike won't start after carb cleaning.

So that is the way it should be done, whatever Berg thinks.

 

Coming from the man who insists the cold start function(Enrichment
circuit) only works at idle with butterflies closed...

From page 5-12 of GS650G manual:
"To check the float height, invert the carburetor body holding the float
arm pin so that the pin will not slip off. With the float arm kept free,
measure the height (A) while the float arm is just in contact with the
needle valve by using the calipers. Bend the tongue (1) as necessay to
bring the height (A) to this value."

No None of us are quite right. It is supposed to be inverted but the
float arm is not supposed to be pressing against the needle valve due to
its weight. Last time I took a carb apart it would have taken a a pin
punch to move the pin and there was no way it would fall out. I tried
punching it out and broke the carb.

Please show me where I ever posted that. I think you have me confused
with another poster.

 

No didnt see any scan. Attachments probbaly got lost.

You do want to turn the carb over but you do not want it to depress the
spring.

OK thats totally different to picture in my GS650G manual which does
show it inverted and not slanted.

Yes, exactly!

As promised, here's an update in the event someone is curious as to
how I fixed the backfire issue.
Just now I finally got to put the pipes back on the bike as I had
decided to paint them, once I had them off the bike. On a site note
painting them with Temclad heat resistant flat black was a good move.
It looks so much better now.

Anyhow, the problem with the backfiring was due to air escaping from
where the pipe connects to the engine. This is an aftermarket pipe and
I couldn't just use a standard part from the many the local wrecker
had. So instead I had to become creative with muffler tape. Walmart
sells them for like $4. I also replaced the brass rings (washers) with
new ones ($5 for the pair). That's all it took. The muffler tape
provided just the right amount of sealing to make the whole thing work
well. No backfiring at all and I can't feel any air escaping. All I
can see is a bit of smoke (from the burning tape which is normal)
being pushed away as I revved the engine.

Thanks to all here for the help. Bike sounds incredibly smooth now.
Carbs are nice and clean, got the muffler issue resolved and now all
it needs is insurance and a plate. Somehow I have a feeling I'll be
enjoying this bike more than the person it was intended. What treat it
is to make turns with this light bike.
