[gustafsonerik]

It's not off enough to cause a problem but inlet on the top right should be set like the one on the left

Re: ARE THE FLOATS CORRECT PICS INCLUNDED

could my lower unit have anything to do with this problem

Re: ARE THE FLOATS CORRECT PICS INCLUNDED

Do your RPM's stay high, while the speed is slow? Or are the RPMs low as well?

 

[gustafsonerik]

Re: ARE THE FLOATS CORRECT PICS INCLUNDED

the rpm's seem low also i don't know if this has anything to do with it but i took out the electric choke mechanism and i only use the manual one thanks Erik

Re: ARE THE FLOATS CORRECT PICS INCLUNDED

The reason I asked is you mentioned something about the lower unit. IF the RPM's stayed up, then it could have been a spun hub on the prop.

Did you make the adjustment as Laddies suggested? Does priming the bulb while it's runniing change anything?
Have to checked spark and compression?

comp.spark all good priming makes the engine stall erik

Re: ARE THE FLOATS CORRECT PICS INCLUNDED

Have you checked to be sure the timing arm is advancing?

 

[Laddies]

Re: ARE THE FLOATS CORRECT PICS INCLUNDED

Priming really shoud not make the engine stall, have you cked. the fuel pump diaphram

Re: ARE THE FLOATS CORRECT PICS INCLUNDED

no but i will tommorow thanks Erik

Re: ARE THE FLOATS CORRECT PICS INCLUNDED

fuel pump diagram looks good no tears if i had a bad one wouldn't it get better if i squeezed the fuel primer..like rev up ??? also would the stator or the electirc apratus under the fly wheel have anything to do with why it only goes 6mph ?????? thanks Erik

comp 115 110 105 125

Re: ARE THE FLOATS CORRECT PICS INCLUNDED

also i've been driving the engine without the cowl and the top on .. would that need to be on for some reason thanks Erik

Re: ARE THE FLOATS CORRECT PICS INCLUNDED

Squeezing the primer with reasonable force shouldn't change the motor operation. You might have bad needle valves, or crud in them.

Is it straining trying to go, or just not trying?

 

[Plainsman]

Re: ARE THE FLOATS CORRECT PICS INCLUNDED

Have you cleaned and rebuilt all the carbs? Do you have a manual?

 

[gustafsonerik]

Re: ARE THE FLOATS CORRECT PICS INCLUNDED

thanks i check this out

 

[Laddies]

Re: ARE THE FLOATS CORRECT PICS INCLUNDED

Eric after you have cleaned the carbs makeing sure the high speed jets are clean and have confirmed that the spark advace is working (35 degrees at WOT) that only leaves the high speed winding in the lighting energizer if you need to ck that we can give you the OHM readings. (380 to 420 ohms on the low speed and 9 to11 on the high)

laddies thanks i really appreciate it i'll clean it tommorow and take her out thanks again Erik
