last night it was kinda surging at wot and rpm dropped fromm5500 to approx 4000 , i thought that i dropped a cylinder because of the loss of power. I limped back to the dock just to be sure and when I go there it won't idle up to the dock it just stalled.

This evening I put it on the muffs and it wouldn't start. Checked compression and it's ok , checked spark with a timing light first and then got out the testers and it's all good so that jsut left the fuel.

Removed the air silencer and one of the primer lines , nothing out the line when the key pushed in , so removed the line into the carb and turned the key and got nothing. Squeezed the bulb and fuel flowed , then tried the key again and it didn't pulse.

The filter is good and the pump was only done about 6 weeks ago but i reckon that it is my prob? should i whip it off and check it or is my issue something else ??

Re: is it my fuel pump??

maybe i'm over thinking this. Rules for 2 stoke are compression , spark and fuel , correct?

so good comp , good spark leaves fuel. but i know that the carb bowels are full so therefore it should fire up. Maybe the carbs are my issue but these were fully done 2 months ago and I think it's odd that they all are stopping fuel going through....


having said that, the solenoid clicks but no fuel comes through so maybe it isn't getting the boost of fuel to help it start when cold....

anybody any suggestions folks?

It's weird that it ran fine right up till yesterday and now it won't even start up.

You checked that "darn" lanyard switch right? Also possible something is plugged up.

So according to what you have already done I would say you found your problem.

"Removed the air silencer and one of the primer lines , nothing out the line when the key pushed in , so removed the line into the carb and turned the key and got nothing. Squeezed the bulb and fuel flowed , then tried the key again and it didn't pulse."

Unless you have an air leak in your fuel line before the fuel pump I would your fuel pump is finished.
