FarmerTec 660 "Kit" - What's the latest on quality?

[Jason628]

Grinding is done just gotta blend it and polish exhaust. May have messed up my port timing. Intake had a big wall of plating with a void behind it that was really hard to see. We shall see how far off my timing is... I'd bet my intake dropped at least 4 degrees.

 

[Wanab]

That's what the make JB weld for.

Yeah. We'll see how bad it is. If it is 75 degrees or more I'm not going to worry about it. My first reading was 80.

 

[Wanab]

If it was 80 and you lowered it how could it be 75?

 

[Wanab]

Latest on quality? I would say pretty good overall. Fit and finish I rate as average so not bad for china crap. Everything went together like it was supposed to. Only issue was a sharp edge of flashing on the recoil handle ends.

Farmer Chuck was feeling his oats coming in at .025, 101/125/80. Now he's gettin'ready to get his drink and his two-step on.

Yeah I think I'm bassackwards. Sorry. Brain is functioning at 1/3 capacity.

 

[Wanab]

Just breakin' in Farmer Chuck. Had him spun up to about 12K piss revving it.

 

[Wanab]

Unfortunately Farmer Chuck suffered a lean seizure as a result of a reckless tuning session. Always practice safety when you play with your screws boys and girls.



Now its back to the grinding board for a do-over.

Looks like the rings spun past the locating pins

 

[MustangMike]

Yea, with an addl break on the second ring to the right of that.

Wonder if the ring spun, or went in wrong.

 

[Jason628]

I agree with the above statements. Locating pin doesn't look like it was doing its job very well. Every one I've built will not idle with factory settings. Always have to turn up idle and lean out the low and high about half a turn. What brand piston is that?

Nothing nearly that dramatic. Ring is moved because I fiddle *f-worded it inspecting it when I opened it up. No catastrophic failure. Piston cleaned up fine when I rubbed some 400 over it and the jug was unscathed. a true testament of the durability of the plating

Did you lean it out after the video? Did it totally lock up on you? I've had luck leaning it out until it starts to sound clean and then turning it back about an 1/8-1/4 turn.

 

[Wanab]

No, it was tuned properly in the video. Never locked up and the Farmertec piston did not crumble.

 

[Jason628]

I need to eventually find time to do testing of my stock saw versus the modified saw and get an accurate comparison.

 

[Wanab]

Bad news on the quality front. The carb in the other kit I received was DOA and resulted in a no-run condition as fuel poured from the exhaust and decomp with the L screw bottomed.

Did you pop the covers on it?

You get that on these jobs. Probably forgot the spring or the needle.

 

[Wanab]

No i just slapped a Walboro on it.

 

[MustangMike]

Check the fuel lever, I had one adjusted wrong on a 660 kit that did the same thing. Adjusted it and it ran fine.
