Carb spitback robbing power

[Moparmyway]

I dont seem to have this problem Brian

Oh yeah, I just remembered why I run MaxFlow filters

 

[jmssaws]

Blowing a hd2 out won't fix it,I've seen them that looked brand new and still be clogged.

The white hd2 knock off dave sells is a much better filter or like Kevin said run a maxflow.
I will literally use any other filter before a hd2.

Them guys in Australia have found that out also.

I've bought this one from HL - http://www.hlsproparts.com/Stihl-pleated-air-filter-replaces-0000-140-4402-p/h50460.htm
and this - http://www.hlsproparts.com/Stihl-heavy-duty-prefilter-replaces-0000-141-0300-p/h50300.htm
Not sure how good these are over time, any one else try these? Saw did get instant relief when I changed it though.

On the HD2's I've used 200 psi worth of air and that seems to do it. Sometimes solvent spray works nicely and doesn't eat at glue like brake cleaner does.

This is conspiracy , the HD2 is the best performance enhancer know to a chainsaw..you guys are losin your minds.

will probably get one of those filters J along with another max flow cage

A plugged filter makes for a richer mixture so it should have more power!

I ordered one of the 661 kits kev , id say the fit and finish is awesome.

It actually needs that air flow to pull the fuel. So it actually runs leaner by pulling less fuel.
Ok now my brain hurts.

I've ruined a few filters using carb cleaner to clean them off. As they dry the filaments that make up the filter kind of melt together and a perfectly new looking filter won't allow you to even breathe through it. I don't recall this happening with the black hd one but the tan ones from a few other models and brands took a hit.

It certainly is ............ Joseph went to great lengths to produce these kits, and I am very impressed with the results.

I can slice and dice a huge tree, cut the stump flush, (6 tanks of fuel) pull the cover and see no reason why I cant fuel it up again and cut some more. Ive gone 10 tanks and still seen a clean filter.

I wish he would re-do the 066/660 filter kits so that they fit and perform as well as the 661 kits do.

I read a few years ago on Masdens site under saw facts that a saw running wot for 5 minutes or something breathes more air than we do in a year....unrestricted filters are a must for performance.

I'll have to agree with J here. I'm not an hd2 fan at all, with or without the outerwear pre filter.

I mostly run max flo on saws that I can. Or a velocity stack, then your filter options are endless

I remember i kept having to turn the h screw in about 1/8th of a turn every month or so on my 395 and never thought much of other than whats gonna happen when its all the way in , anyway it eventually happened so i rebuilt the carb and it was still the same , replaced the welch plugs in the carb thinking fuel was getting past but still the same , tried a carb of my older 395 and no difference , then after pressure testing and replacing anything that moved with no luck i noticed the top of the air filter kinda sucked down so i replaced the perfectely good looking filter with a new one and problem solved ...
Man i felt like a dick

Ive given them a go just about every way i know how , i settled on the 2 maxflow plates with no cover and an outerwear as the best way i can run the hd2 ... and im still not crazy about them...but thats bein kinda picky.

Idk who can argue the benefit of a maxflow ?

Me too , the other kits seem kinda cheap compared to the 661 set up , but they still work so its all good.

 

[jmssaws]

I don't like the maxflow cover and I don't like the filter in the open.

I think the 661 cover is way nicer than the other models my dude , they work..so i dont really care.

I've not seen one of the 661 setups
the 660 is not a great looking peice
