Does it have an internal governor?

I think that's the problem with mine, I bypassed it to get better throttle response. Well now the throttle response is incredible, but the saw runs lean at WOT.

When I started building my Poulan 5200, I was told to use the 4200 donor saw's carb cause it didn't have a governor valve.

Possible when you blocked the governor, it may have restricted the hi speed fuel passage.

[Kensie1988]

Mine has no iternal governor that i know of.

 

[Kensie1988]

Throttle response is good and the winds up good the the longer i hold the throttle the leaner it gets until it starts cutting out.

Looked up the 3400 and all it says for carb is WALBRO. Bet a dollar to a donut I have several in the boneyard.. I don't do poulan so be proud to look.. I'm in Spokane, Washington.. I'll get back to you on this page a little later.. Dealing with licensing so who knows how long.. It's a government thing.. K
