ProV 150 Misfire

[Craig P]

I have an 86 ProV 150. Motor starts and runs good but when it's idling but I get a misfire about every 5 to 10 seconds. This causes the rpm to drop and a fine mist to be sprayed from the bleed system. The spot that the mist eminates from is on the starboard side behind the top carburetor, (this hose comes from the bottom right (starboard) cylinder. Checked all carb and timing adjustments, everything seems fine. Anbody have any idea what it might be?

Thanks,
Craig

The rubber hose appears to be connected correctly, (there's a little U-shaped part that it connects to). That's where the mist of fuel comes from when the misfire occurs. The mist of fuel coming from the hose is the effect. I'm trying to determine the cause. If you'd like to send a picture that would be fine. My e-mail address should be under my profile. Appreciate the help.
