Fluidyne Allison 1000 High Performance Transmission Fluid Cooler 06-10 GM 6.6L Duramax LBZ/LMMAnyone who has spent time pulling a trailer through the mountains, sitting in summer traffic, or making repeated long drives in a Duramax knows how quickly transmission temperatures can creep up.

Honda product and quality.
Do NOT understand why my lawnmower with a Honda engine did not come with a Honda carburetor. Replaced with this Honda carburetor and starts easily. The other carb only lasted 1.5 years.

Worked but not well made. If you need 24 hour turnaround only option.
The housing is 95% identical. Float valve seat is smaller than mercury/quicksilver. The carb I received was stuck wide open. Had to completely pull it apart to fix the throttle. Then the choke didn’t work correctly. So I ended up putting this housing on with all my old mercury carb parts inside. All I needed was a new float valve but they are back ordered indefinitely. So this worked because the housing is correct but that’s about it. Internals were plastic. Not metal. Jury is still out on the jet size. I’ll update if it floods the motor at speed. Seems to be running very rich. If you’re looking for easy, I’d buy the quicksilver that’s tuned for the motor already. The carb I received idled too fast and even if the throttle wasn’t stuck open it wouldn’t have run well with a racing choke (screams air leak because of poor quality)

Throttle pin defective
This carb fits my tohatsu 3.5 hp but the throttle pin is defective. The only way to regulate it running wide open is to choke it out.
