Can any of you fine folks out there help me, I'm getting my back up unit set up, and on this Prochem Blazer 16hp. There is an electric small square box connected to a circular thing, on the top it says Pro Fuel, has numbers 1-6, this then goes to fuel pump on the Briggs,v when I turn key on the brass box clicks rapidly.... My question; What is this Pro Fuel dial for, what number do i put it on, for cleaning.....?
Thank You for any info... Scott

I'm not seeing that dial in the original schematics, it's a fuel system of some sort but I don't know enough about that (albeit upside-down) rig to say what exactly it is. Do you have a secondary fuel source for heat?

I had one of those on my first TM. It was VERY problematic. I remember replacing it at least a couple times in only 3 short years. It is a fuel regulator. What I suspect is your fuel pump puts out too much psi going to the engine so this regulates it down so the engine can run w/o flooding. My best suggestion is to buy the proper fuel pump for your machine and eliminate the regulator all together. A B & S engine can only have like 2 to 4 psi to run. Not sure of the specs on Kohler. I would call either Jondon or Interlink and get another fuel pump if it was mine. I think I normally ran my first TM with an 18 hp B & S engine on 2 or 3 on the dial. This is the fuel pump I'm using right now for my 21 hp B & S on my Boxxer 421. Note it's only 2 to 3 psi. No problems with it. http://www.jondon.com/fuel-pump.html

I think that thing may have contributed to some of the engine problems I had with my first TM. I'm not a mechanic, but this is my opinion. Those regulators are sold under different brands btw, the one I had was a NAPA and looked identical to the one you have. If you're having flooding problems that kill the engine turn it down to 2 and see if the engine runs at full rpm. If not, go up to 3. If it still doesn't run I'd get a new one. They're pretty cheap and you should be able to get a local auto parts store. Here is one I found right quick. It shows the numbers are actually psi settings.

That dial looks like it is either maxed out or turned completely off btw. I'm thinking it's turned all the way up to about 6 ps. I'd be surprised if the machine runs for long w/o flooding at that setting. I' definitely turn it down to about 3.

Toss it all and put in a low psi fuel pump, and buy 2 while you're at it so you have a spare.
Having a spare is not a bad idea. I just replaced my original fuel pump on my Boxxer last year. It lasted well over 14 years. The pump I have now is different, but seems to work fine. I had already bought it long before my original went out so I was ready when it did.

I'd also replace that fuel filter too. You can get it from Jondon or local auto parts store for a few bucks.

I have one that quit after less than a year in the middle of a job. Fortunately I planned on it so I had made the wiring a plug and 2 hose clamps. Swapped it out in 5 minutes

I had a lot of trouble with mine. If your engine isn't running smoothly at like a 3 psi setting a new one should solve the problem. Seems like I had to replace mine like annually. A new fuel pump is the best solution over all.
