Engines Problems

My buddy has been gracious enought to let me borrow his whaler this fall do a little fishin. The 1985 Envinrude 90 hp ran great the first couple of times that I used it but had a little bit of a "Tinny" sound to it. About a month ago I took it out on a Saturday and it ran great all morning. Came back to the dock around noon to drop off a couple of folks and had a hard time getting it started. The ignition was loose and I thought I had just flooded it a little while I was tightening it up. Note to self, never hold the back the ignition and turn the key. Anyway I got it running a went fishing for awhile and after the first drift I had REAL problems getting running so I headed for the hill.
The next morning it started up fine, so I headed to the coast and fished all morning no problems. That afternoon, I couldn't get it started and had to get it towed back in. I spoke with the guy at the marina and said that older engines are harder to get started once they are hot and that could be the thermostats.
I picked it up last week and they said that they couldn't find anything wrong with it. I've got the mechanical inclination of your average 3rd grader, so if anyone has any suggestions I would greatly appreciate it. It's to cold outside to breakdown. My buddy said that he's had the carburators rebuilt in the past 2-3 years. Would that make a difference?

He's the only Evinrude guy I ever deal with.
Doesn't sound like anything is wrong. My best guess would be some water in your fuel, a clogged fuel filter, a kink in the fuel line, or just operator headroom.

Operator headroom is very likely

, but it ran fine up to that point and I had been taking it out everyday or every third day. A guy on the FS forum said he thought might be the Stator Assembly. Any chance it could be that? Thanks for the help.

I've had similar experiences (starting problems when the engine is hot), Now I put the engine in neutral, and advance the throttle to 2/3rds and usually she turns over on the 1st or 2nd crank. She gets a little finiky sometimes if I don't let her run burn off alot of fuel and let her streatch her legs really good. Changing your spark plugs regularly also helps. I always pre-mix my 2 cycle oil and some
Sta-Bil and a little bit of Acetone to each tank before each trip. BTW mine's an evinrude 1978 85hp... and I've become somewhat emotionally attached to her.

mjsigns...I was right there with you until you got to the acetone. Please tell me what the acetone is for? I am thinking to cut the varnish that gas leaves when it drives????

Acetone is supposed to help the gas burn more efficiently in the pistion combustion chamber, and may help clean out those gummed-up fuel jets. I only add 1 oz for every 8 gallons in the tank. (pre-mix before adding the fuel into your tank). I have not noticed any gas mileage improvements....
Here's an article about it if you're inclined.... Wevans also uses acetone ...

Makes sense to me.

Thanks again. So you use Sta-Bil even if the boat is not going to be sittine for awhile?

Does Acetone cut varnish - like the kind you get in a carb that has sat for a year without any StaBil in the gas? I'm talking about after you break the carb down and are trying to clean the gook out of it before putting a kit in it.

The Business-
I use sta-bil reguardless because I never really know if weather conditions will allow fishing every weekend. There have been (or could be) a time when there is a long windy weeks after weeks, or the wifee slams me with a giant to do list, or in my current case, I'm having surgery on my knee in the morning at TOC. (basically It's just good to know that you can miss a weekend an not worry about your fuel going stale)
KarstRanger- Acetone is an industrial solvent, and it is woth a try for the build-ups in your carb. It may eat or disolve plastic parts if not removed quickly....
Thanks !

Thanks mjsigns - If Acetone is strong, then I understand that rubber or plastic parts are verbotten. I had been searching for something stronger than CRC choke/carb cleaner spray or stright gasoline -and Acetone may do the trick.

Thanks-
Since they will be working on my
left knee, I marked my
right knee with a couple dollar signs "
$$" and the word "
NO".

The operation went smoothly, I guess... I slept through it all.
A few minutes ago while I was in the bathroom, I noticed Dr. Haney wrote the word "
Yes" above the bandages on my left leg...
Who says Dr's don't have a sense of humor
