Should I do anything about this residue?

The clean-up work looks good!

Trusting that the bolt inside the port will of course be removed before attaching the hose.

With a snug fitting hose it's often helps to first soften the end of the hose by applying heat so that the hose becomes much easier to attach, which may result in a tighter attachment that doesn't require a clamp. And this would also include fuel line hoses.

My preferred hose-end heating technique is to boil a cup of water and dip the hose end momentarily into the very hot water, which quickly evaporates leaving the hose end nice and soft. And which avoids the possibility of accidentally overheating and burning or melting the hose end as is possible with a hair dryer, heat gun, light bulb, or flame.

Good Fortune!

Good way to blow the seals. Ditch the bolt. :dry:

You have shoved a bolt into the breather hole! TAKE IT OUT!!! That breather is there for a reason. Put a hose on it to connect it to the airbox. If you leave that bolt in there you WILL have engine problems. Ed

Re read the last post by him ..... in it he does say he is going to heat up and re attach the breather hose so we all got excited for nothing .... :laugh: :silly:

:whistle:

Carb holders should be installed without any sealant.

Where there's evidence of sealant having been earlier applied, it was perhaps done in an effort to seal air leaks in an old worn out holder.

Most sealing efforts are temporary at best, but may last a week or so which should hopefully allow sufficient time to acquire brand new holders.

Sealant products may be fuel proof or heat proof, but likely not both as would be needed for carb holders.

However, sealing efforts have reportedly been longer lasting with ThreeBond and similar products, such as:

The best remedy by far is to install brand new carb holders.

I misunderstood. Somehow I thought he was going to heat up the engine - as in running it. Maybe I should wait until the sun is over the yardarm before pulling the first cork! :woohoo: Ed

I appreciate the enthusiasm guys! The bolt is only there to keep crap out while I'm doing all the cleaning.

I can see why y'all would WTF after seeing the picture! I took a different picture with the bolt removed but mistakenly put the one you see up. LOL sorry for my duh moment!

I have new ones but wanted to get the old stuff off so that it didn't interfere with the new seal. Thanks for the boiling water idea too patton!

All done with this part. The boiling water idea worked well to get the tube back on.




And the nail idea worked well to get the crap off the mating surface. Hoping to find a local source of stainless steal allen head bolts for the carb holders.

Hardware store or HD for SS Allens.

After fighting trying to put on fuel line now you tell me. lol great Idea Thanks Patton
