Heat shrink on the carb holders

[SanDiegoMike]

Any of you ever used it? PO slathered mine w/a LOT of RTV...manged to get it all over the fins as well. Looks like...well...you know. I'm wondering if covering them with heat shrink would be an option, or would the heat from the engine cause problems for it. I'm trying to find a way to make it look better w/o spending $100.00 for new holders.

Just clean all the rtv off real well, and wrap them with electrical tape. It looks good from a few feet away, and stays stuck. I did that with Wildkat's bike, and it's held up well.

coating

I've heard of people using this Plasti-Dip coating on those carb boots. Napa auto carries it, but i'm not sure of how much heat it can handle. HTH.

Plast-Dip works pretty well, and will withstand the heat in that area. But PartsNMore sells the carb holders, new, for only $90.

Try that link.

Mike,
IF you get the LARGE heat shrink, it should work. It will loose about 30% in size, so choose a size that will just be snug when you are done. You can even change the color, if you want!!

I just posted a reply to another thread about this very topic.

Here's an alternative to Electrical Tape!

where in the world do you get heat shrink that big???? Biggest I have seen it is about 1/2" diameter before it gets heat gun.

Thanks

Try an electrical supply. Used to terminate big cables. That is an idea , you can get 500 or 750 MCM heat shrink with environmental sealant on the inside. Seals terminations from the environment.
Have to look into that. Temp is the consideration. High voltage stuff should handle it... but
Anybody have any idea what the temp is running on the backside of the engine on the carb boots?

Thanks John!

Thanks for all the input from everyone. I like all of the heat-shrink info.
I couldn't take looking at the carb holders one more day, so I went with Johns suggestion. If it's good enough for Wildkat's bike, it's good enough for me!

[John]

Thanks

How does it look?

[SanDiegoMike]

So far so good...

Looks a whole lot better than before! PO slathered so much RTV on them (WITHOUT removing them from the engine ) that the gap between the oil line and the #3 manifold was completely filled in!! I also noticed (and didn't make the connection until the next day) that there were NO gaskets between the manifolds and the head. Please don't crucify me too much for asking this, but...there should be gaskets...right

[DiverRay]

NO GASKETS from the factory. The original had an "O" ring that was part of the rubber cast around the mount. They CAN leak, so a check for leaks would be a good thing.

Mike

If you should find a leak where the boot is attached to the head, and find the need for a gasket, you can use a thermostat housing gasket from a 2.3 liter engine in an older Ranger or a Mustang. The bolt pattern is correct, and with very little trimming it will work well.
