Hot Start Problem

[Still Plays With Toys]

I have a Savage 21 that I got when it first came out many, many years ago. As I posted in my new member introduction thread I hadn't run it in years. It runs great. It starts right up when cold. After I have run a tank of fuel through it it doesn't want to start. After it cools down it will start. I remember reading about this problem on the forums back when I first got it years ago. However I don't remember what the solution is.

I have not experienced this, but I have read posts about the engine being too hot, getting the carb too hot.

The engine doesn't have that many hours on it plus its done it since day one.

I seem to remember the problem was something like this. I monitor my engine with an infrared temp gun and keep it in the recommended range. I just don't remember what the solution was in the thread I read many years ago.

Mine does this if I run out the tank or it flips and runs lean and dies and I imediatly try to restart it. Reprime the engine by blowing on the pipe pressure line and you will hear the fuel boil. When it stops boiling it will restart.

Ah... Now I remember. I'll try this.

I wonder if there's any way to insulate the carb so it wouldn't heat up.

Thanks... I tried your suggestion. I blew on the tank pressure line and could definetly hear the fuel boiling. I blew until it stopped boiling. I then tried to start it and it wouldn't start. I suspect that there still wasn't fuel in the carb. Even though it wasn't boiling it was evaporating. So I blew on it some more. Then I had it flooded. Once I cleared the fuel out it started right up.

So your suggestion works.

I use a roto start. After the boiling stops I hit it with the roto start and put my finger over the exhaust on and off for a few seconds and it starts.

I just hold the throttle wide open as I pull the starter. Once it starts, let off the throttle. The extra fuel/air going into the carb with it wide open cools it and it usually fires up within a few quick pulls.
