Tohastsu - 8hp 4cycle - tech questions
Here's the story - purchased the Tohatsu 8hp 4 cycle last summer - so it's relatively new.
Used it frequently traveling on the Chesapeake and down the ICW. All of a sudden, it would not run slow. It would start right up, first pull, but when taking it down to idle to put it into gear, it stalls.
A friend who has the same engine told me that he had the same problem and it cost about $200.00 for a mechanic to fix it. Apparently, the slow jet in the carburetor clogs because of ethanol in the fuel.
I got busy and downloaded the parts manual PDF, located the slow jet, removed it - cleaned it, put it back together, and miracle of miracles, it worked!
Damn. I mean, darn.
I thought maybe the idle had to be adjusted - but not so. And I hate to take the carburetor apart every time it clogs - which so far is every time.
Is there something I'm missing / don't understand?
Is there a downloadable repair manual on line anywhere? I can't find one.
Is there some kind of fuel additive, or cleaner that I could add to the fuel or spray in the air cleaner? (I have been told there is not - but not by professionals.)
Apparently I need to purchase non-ethanol fuel in the future to prevent this from happening. I am told that marinas in the south have it. Is this true? And what do I do when I get back north where apparently it is not available?
Is there some kind of slow jet for that engine which would accommodate the ethanol fuel?
Am I asking too many questions?
Right now, we're sitting at anchor in St. Augustine and the weather is beautiful - and we can't go to shore cause the dinghy engine is crapped. Soon, I will probably feel the wrath of Saltwater Suzi, so, HELP!!!
