you have so much fuel that it isn't burning it off. you are a mixture of wet and super wet and that is why you get the flames.

Ok, thank you, but Why the engine is very hot after 5 minutes from start and the water is boiled ?

Is the FP tuned exhaust ? Or is it stock exhaust because in the manual is Main jet 182
Pilot jet 40 (I have 40, 42, 45) and Needle OBDVR 5th from the top, but when I set from the manual the spark plug is yellow.

When I set the Needle on the 4th from the top and use 42 Pilot jet and 182 Main jet i don't destroyed my engine ?

And last question is :

My set is 182 Main Jet and 42 Pilot jet and 6th from the top and when its dark and I turn 1/4 a gas I see hot and red Exhaust collector, Why ? Because it is a very poor mixture ? BUT Spark plug has very good brick color .

And How many turns on the mixture screw ? I use 2,5 turns


Thank you very much .

never go by the plug colour.

unleaded fuels ruin this old way of doing things.

most of your combustion is probably taking place in the exhaust. it is so rich....
