Honda Spree and Elite 50 Forums

I have a 1987 Honda spree 48 mm bbk 21 mm pwk carb. Was using the oil pump plus premix. Now I'm running 32:1 premix with yamalube r. Smokes alot at idle . I started jetting down the pilot jet it was a 42 now down to a 38. At each size smaller it smoked less. But still smokes and will stall out when I throttle down whe riding. Also my clip is all the way up and the idle speed screw for the slide is out. So it's idle is running on the pilot jet only.
The main is a 95 jet

That's because with the pump and your premix you are running at least 24 to 1. Back off on the oil in the tank by half.

I took the pump off it's just straight premix..

I would then say that 32 to 1 smokes a lot compared to using the pump and that Yamahahah lube is smokie.

So I should just tune it up and not worry about the smoke.Do you think the 38 pilot jet is too small? Or maybe try another mix. When I let off the throttle it will stall out not sure if it's lean or rich .
