Starting Stumper

[GFNER]

My 95 Trail starts on first pull when cold but the last two times out would not start when warm. Good spark. Seemed to be lacking fuel so I removed the plugs, full choked, and pulled it over about ten times , reinstalled plugs and got it to fire. Any ideas? Only does it when its warm.

Bad gas may have fouled the carb. You need a carb kit and service.

I recommend always using a fuel stabilizer.

Try not choking or half choking when it's warmer. It maybe running richer then?

A sled with a choke in that vintage (fuel enrichment) that starts on first pull when cold is not right. There shouldn't be any fuel available till the engine turns over to operate the fuel pump. In this case more then one pull. You have an incorrect fuel level(too high) by improper float drop, or leaking inlet valve.

You probably flooded the engine. It takes less fuel to start an a warm engine or in warmer temps.

Pulling the plugs and pulling it over it what you do then.

The choke isn't going to do anything with the plugs pulled because you lose your impulse from the crank and the fuel pump won't pump.

On the front of the engine near the bottom of the crankcase there shoud be two 6mm brass plugs sticking out the front of the case. Remove those and see if fuel runs out. Most of the time the culprit is worn needle and seat in carbs allowing fuel to pass by and flood the machine and collect in the lower crank case. Had a older 440 did the same thing. Could pull till you were blue in the face till I drained out the case, then it would start in about 3 pulls afterwards, then just had to remember to shut the gas off after each ride till I got the carbs rebuilt. (something to try)....
