Thanks a lot Kaptain! This gives me new things to check. I noticed however that one of the rubbers between the carburetor and air box was rock solid and not very tight against
the air box. I put them in some brake fluid in hope of getting them softer. I still can’t see its SO sensitive but I may be wrong. My experience is only 2 stroke engines and snowmobiles so can’t really say anything about these four strokes 🙂
I plan to change out the diaphragm just to ensure they are in good order, did anyone try the JBM ones? Looks like the only alternatives if not pay huge amount of money.
Do you know a place where I can buy the new rubber boots for the intake and air box to carb?
