How much of the rubber mat can be removed and should it be replaced when putting back together??
Thanks again for the help
1st, would you Pretty Please fill out your Profile so that we know your location???
This post is precisely why we need to know where you live....
If you live in Arizona, southern NM, or middle to south Texas, you need to replace that mat....
If you live further north, I would leave it off.
The purpose of it is to try and isolate the carbs from the heat that rises off the cylinders when the engine is hot and sitting still.
ie, you stop at the DQ and go inside, sit for 15 minutes, and go back out and expect your ride to start..... if that mat is gone, and you are in 105* weather, it probably won't... it will be vapor locked.
I used to live in Phoenix, AZ and had to work on my vacuum lines. When I bought my '94 it was a rotten mess down under.... I wanted to tear that mat out and get it gone.... but was talked out of that.
