Troy-Bilt TB675EC Trimmer

[chucketn]

I have adjusted the air gap as close as I can get it without interference on the flywheel. Interference at .010 or the thickness of one business card, adjusted to maybe .015". Seems some fins have more flash from casting than others. Still no spark. I have come to the conclusion that the ignition module from Jack's is NDG, DOA...
I will request a RMA and a replacement from them. Hope it doesn't take another three weeks...

On the advice of a friend, I reset the module air gap with a brass feeler gage at .012", checked for interference and tested again, no spark. Frustrating...

Chuck. Are you getting .005" wobble from the flywheel? Again I never had your model, but my Ryobi did not run out when turned by hand but did have shaft looseness. I wanted to look at the "main" bearings and learned that on the low end units there is only one bearing. It seems these are built to price and are throw aways, not repairs ( don't know if this applies to yours). But yours is still young. The clutch on my Ryobi was held on by a phillips head machine screw that I could not reach. I finally ruined the clutch getting it off and never did get to the bearing. I did have contact, magnet to coil. If jack cooperates see if he can exchange the module for different brand name, and look around a little to get an average price .

motorman, I don't detect any wobble. Seems the clutch on the older one is held on by a K20 screw as the rest of the screws in the unit. It's just too deep in a narrow hole to reach with any of my tools. I have requested a RMA and replacement of the module from Jacks, but have not heard back. Haven't found the part on any other site except E-Bay where they go for ridiculous prices. I really hate to throw this unit away at 2 years old. Maybe time to get a goat!

Round and round we go...
Called Jacks today as they hadn't responded to my online contact for a replacement . Nice lady asked for more info, so had to go to the unit and get another # for her. She discovered that the model # I had called for a different part # module than the one I ordered. By the way, I ordered the replacement based on the part # on the original module I took out. She said her supplier wouldn't warranty the part as I had ordered the wrong one! Why did Troy-Bilt put that module in if it was wrong?
There was a price difference of $0.98 in the parts, the correct one being more. After talking about it for a couple of moments, I offered to pay the difference in price. The nice lady said she'd send me the "correct" part at no charge.
it is of course back ordered, so another 2-3 weeks wait.
Poor customer service from MTD or whoever Jack's supplier is, but good customer support from Jack's.
I'll probably order from them again.
Any Troy-Bilt reps or experts here? What do you all think?

Just a long shot...maybe...maybe there is a difference in compatibility of magnet and receiving electronic parts potted inside the module. The final spark buildup happens based upon measurements we can not make at home. Tell us wha happens with the replacement part:thumbsup:.

Troy Bilt site wants a "41" or "42" model prefix for coil lookup. Have you tried that? Does your model have a numeric prefix?

Point being, the original module worked for nearly 2 years, but was the wrong one? And replacement, same part # does not? Somebody needs to get their info straight as well as QC improvements.

If there is confusion at Jacks it may be helped by Troy-Bilt data base. There are 2 modules with diff pns appearing under the basic model no. There are also 11 digit suffixes to define "new" vs ?"old." There is a chat function there. And the $15 price there is impressive if the part is a good one. Module pn's 725-06012 vs 763-08209. You probably know this by now.

Yes, I understand the difference. As I said, I ordered based on the part # that came out of the unit. I had not seen the second # that the lady at Jacks asked for. Just for grins, I might go onto the Troy-Built site and ask about it.
