Re: 37, 120 carb percolation problems

Again, thanks for all the ideas! It is close to 100 F in the Reno area this week so it has been a good time to try to solve my problem.

Today, I wired the heat riser in the opposite position it is normally in and the problem got worse. In deed, the manifold was so hot that it the leaking gaso would crackle when it hit it!!! So, I am going to wire it "open" like it was initially.

The bowl vent is open. I made sure of that when I rebuilt the carb.

Today, I also manufactured a "pan" to go under the carb with a drain. I will install that tomorrow. It won't fix the problem but at least the fuel will not be flowing directly on the manifold.

I watched the fuel empty into the throttle body this last time and it is quite a bit of fuel, like the whole bowl full, so I do not think lowering the bowl level is going to do much!

Starting to run out of ideas!!
