The problem

Very hard to start

Left cylinder cuts out under part throttle buts fine on idle and wot.

 

Trying to figure out where to start

Where is the needle?

[Jonny72888]

Where does it cone stock? That's where it is. I never change it .

[shakar]

id check caps and coil to start .30pilot seems abit fat.prob not your issue but imo id go down to a 27 1/2. im guess you have duel carbs and a 2 into 1 filter set up.it would' nt be hard to sync a 2 into 1 intake . goodluck

I had27.5 and it seemed lean.

Ill check the cap.

Choke tube?

[Jonny72888]

Choke tube is inplace.

Si I switched the plug wires from one side to the other and it got better was ut still not 100%

That doesn't make sense. They fire at the same time. If the wire or coil was bad shouldn't the problem switch sides?

Electronics can be intermittent, still check your coil and caps. Clean your carbs again.

Are the little caps on the spark plug tight? Did you gap the plug?

[Jonny72888]

Yea the caps are tight.

The plugs are pre gapped to 34 I think and I just leave them there. Never had a problem before. Should I try another gap. This is also the 3ed set of plugs with the same problem.
