My mower was bone stock from Sears with the engine that big. I did improve the air inlet and air filter and rerouted the exhaust for a while but when the exhaust cracked in a no weld area I removed the mods. It isn't even the big engined model either. The big one is 810 cc and 30 horsepower.Lunytune wrote:Yeah, but Bear, not everybody is challenged to build a Tim Taylor lawnmower.
cubdriver, key is to get the passages clean enough to be able to squirt carb cleaner through them. Then run Seafoam in the tank for a couple of tanks in the initial, and then periodically through the summer, and especially going into the winter and winterizing. I've noticed my Dio is getting a little contrary starting, requiring light throttle, and cold natured. I suspect the passage to my bystarter is trying to plug. I'll try running some Seafoam before I tear into it. I don't mind carb work, but detest pulling plastic.
Thinking about it though, I do have a 99.9 CID (1637 cc) 100 horse V-4 with 4 barrel carb down in the shop just waiting for the one on my 15 foot Hydroplane to break, that hasn't Even misfired in the last 10 years, maybe that need a set of mower decks attached to it or better yet, it could go into my Spree.
