Trigas Convert Kit On Briggs & Stratton Generator



Hello all. I am looking at adding the conversion kit for Tri-gas from:
Generator Conversion Kits to Propane and Natural Gas.
and their system works by adding an adapter between the carb and filter which will eliminate tapping into the carb. My problem is that my generator model 030205, the filter sits ontop of the carb using a 90 degree elbow. This will not allow me to add this adapter since it will not line up. Is there a way for me to change the filter assembly and use a different filter assembly that will sit behind this adapter instead of on top? If so any suggestions as to which one I can use? Any info greatly appreciated. Thanks

Please post the engine number

Engine Number or Engine Model #? If latter it is 210000: http://www.mymowerparts.com/pdf/Brig...S2919-0404.pdf
If engine number is what you are looking for, any idea where i would find this? Here is a link to pictures of what I am talking about:

Maybe I need a straight shaft with a high flow filter? Thanks again

Do these Tri-Gas kits come with a way to change the ignition timing of the engine?? I've always wondered this. I know in any auto / industrial set-up I've seen, The timing is always advanced consederably for propane natural gas applications because they burn slower with less energy than gasoline. I ask because my boss wants to convert the rinks ice edger to propane as it runs in an enclosed building with the zamboni.. Thanks, Roger

They have an adjusting screw of how much propane to pump into the engine so it can idle correctly. This is aside from the adjusting screw on the carb. If you go with a direct induction to the carb, then you would adjust using the carb screw...

The fuel mixture won't change the ignition timing ,tho. Because propane natural gas burn slower, the ignition timing has to be advanced so when the combustion pressure is the highest, it's at the right time to push on the piston to get the most power from the engine. It's going to be like firing the spark plug ~15 degrees after T.D.C. Our Zamboni's have base ignition timing set to (I think) 33 deg B.T.D.C . The forklifts are also really advanced lack power smell bad if you set the timing to a gas engine setting. Are the changing the ign module?? Most small engines are fixed timing..

Not sure on larger engines. On these small gas engines all i know the idle screw is what is adjusted. Might want to contact the company to see what they say in your case...

There are filter housings that should fit, like the one pictured in the manual you showed, but it takes a different engine shroud to accommodate it.

Cheese can you get me a link or picture of what you mean so I can try to track one down? Thanks again

Look at the engine on the left near the bottom as you scroll down in the mowerparts link you posted. I think the engine is a 289700. This should physically fit the carburetor, if you remove the engine shroud. You'll need a shroud that fits along with the filter housing to keep the engine from overheating. http://www.mymowerparts.com/pdf/Brig...S2919-0404.pdf
