wr 426 missfiring and high idle

4 posts in this topic

I got a WR 426-01 with stock pipe and I cant get the bik to run proerly, it starts perfect on choke, and sounds ok, but when i get of the choke it starts to "poff" in the silencer an runs pretty porly, it getts a bit better as the engine gets warmer,

as i get of the gas the idle is still hangin at about 3000 rpm and stays there for about 10 sec. bvefore it gos down to "good" idle an about 5 secs later it stals.

I cleand the carp like 1000 times and checked the jetting, it it stock! I did go up on tje slow jet 5steps but no differance.

it dosn´t matter how the mixture is, it dosn´t react on anything.

Need help...

Check your hot start button. If it is not closing and sealing properly it can cause these types of problems.

Ok, thanx

Is the piston simular to the choke? I mean, the choke has a rubber sealing on the top of the piston, but not my hot start.

Are they supposed to be that way? or are the piston sealing missing?
