Hi guys
So first start of my rebuild bike. Complete rebuild engine

It started right up byt it seems like the right hand side dont really fire or sometimes there is smoke and the Nothing.
Also starting dripping at one point from the pipe? With fuel

It starts right up but yes, Any suggestions
Does the carb throttle slide? Sit a bit low?

That carb slide is the wrong way round.

Arrow is correct.  Slide cutout faces rear.  Most likely you've switched R and L slides and both are backwards...

Is that carb bowel wrong too? I thought the elbows should face each other, on the inside, not the outside.

Ive changed the slide on the right carb so now its cutout faces air filter.
The left side carb was correct
It still has problems

Maybe tomorrow i Will varify they have correct floating bowls

Tips are welcome 😁

Arrow is correct. That float bowl is on the wrong side. It looks like you have them swapped on the bodies.

I suspected this, but wasn't 100% sure on that one. Long time since I owned one of these bikes.

This may confuse the situation and not make much sense at all to people reading.

We have communicated today and the original poster has more than one set of carb. slides.

Forums are great, but sometimes confusing.
It's a massive bonus if we can eliminate some of that confusion.
