New motor need to know hp ? - Page 2

I fixed one of these for my brother in law (pressure washer) Looked like a strong and well built engine and perfect for a mini. I recall the parts (like carb rebuild kits) being a little pricey locally, might be better on line though.

With a carb, header, and tweaks I bet you could get 7 HP easy.

They are very well built engines. The old L-head Hondas were built like tanks too. Not knocking Briggs or Tecumseh because I like them both, but if you compare a rod from a 3.5HP Honda to a 3.5HP Briggs or Tecumseh rod, there's a big difference. Bigger, stronger rod with bigger wrist pin and big end journals. I think the Hondas were actually overbuilt. Some of the old snowblowers have engines that run flawlesly, just like new, but you can't get the parts anymore to repair the snowblower.

well i was not being a DICK like some people and saying that just because it was not a 50hp motor it was junk i have boxes full of 5.5 honda's and 6.5 clones and i even have a real nice 5hp briggs . i meant i did not need a smaller motor than what i already have... thats all . i like robin motors it looks well built ,it just serve any purpose to me i don't have a vintage minibike to put it on ,i'm sorry if that offends some people that i don't have vintage in my garage ,but different strokes for different folks.....

I guy I know on the penninsula just offered me a Robin for 50.00. He said it would slide right in on the Tote Gote. I want more top end on the Gote so I'm thinking about it. Maybe eliminate 1 jackshaft. If I don't have to cut or drill I may do it. But I know very little about the Robin engines.

Those old Robin engines are probably some of the best engines built but I think you'd do yourself a big favor to just stick with a common engine.

Okay, I aquired a old Briggs 5 hp flathead from a tiller. But the crank is larger than my 3 hp Briggs and I don't think I'll find a "climb away clutch" to fit (I think that's what it is called). I would like the Gote to do about 25 mph or so to keep up with N58591's 6.5 DB.

What shaft size do you have? bigger engine isn't going to get you speed I have a 5.5HP with the same ratio and it still crawls, you need to put a smaller sprocket on your top right JS then maybe get a bigger engine to handle the higher gear ratio. You want to keep up with the DB? gear it the same as the DB,, I KNOW he cant climb the same hills your Gote can. (apples and oranges)
