and watch it possibly catch fire.by spraying it on a running engine
Starting fliud (Ether) is highly flammable.
Use Carb and choke cleaner instead. It’s more stable and less likely to flash fire but will still burn when drawn into into the engine via a vacuum leak.
Some folks even use WD-40 for this.
If you can get in touch with Bill, he would be the best source for info. Bill will tell you that the whole intake w/ carb attached can be removed in 5 minutes.
Ship it back to him and he will install it on his car to verify proper operation.
