Blue 253 warm starting issues

[Taily]

When it does start and idle when it is hot does it smell/look like it is fuelling-up?

All quadies have a couple of plugs under the main jets that are prone to dribbling fuel. I'm tipping if not a vac leak as previously mentioned it will be a pretty sure thing that one or both of these bad boys are leaking and piddling fuel straight into the throttle plate. Google is your friend to fix them, there is plenty of good info on the net about how to seal them up and get it running right. They look like a big complicated carby and they can be a little tricky to tune exactly right over about 300hp but they can be conquered.

A carby kit, a can of carby clean, a few basic screwdrivers and tools and a couple of spare hours one afternoon and you can have it running sweet again.

I could smell fuel with bonnet down about 10 mins after switching it off and it had only run for 30 seconds this arvo. When plug gap was 1mm it ran pretty OK after it fired when hot. Now with gaps at 1.5 it is rough for a fair few seconds longer and then runs fine. It so suss that it fires immediately with no hesitation and no pumps when it's stone cold, try restart it more than 20 seconds later, dreamin.

heard about the wells than need to be filled with epoxy. another bloke suggested needle and seat issue and another a float problem. I really want to rebuild one but i've seen one apart and it freaks me out! what a mess. The same carby bloke I use pulled one down years ago and showed me the base was warped and then asked me if i wanted to spend $750 for him to rekit it... when I said,, ah no -he boxed it up in 100 bits and sent me home

Get a second opinion on that carby

got anyone close mate? I have a mechanic that will rekit and clean it etc for $70 plus cost of kit. If it needs parts, he has none. He's pretty old school so i trust he's got some idea.
