Anyone know a source to acquire these tools ? I'm looking for Thexton tools 362 and 370 so I can tune my rebuilt E4ME and get the car running again but I'm having 0 luck finding a distributor that actually HAS them. Instead I keep finding distributors with listings for the tools but nothing in stock. Help please! Also, what dwell meter do you suggest? Analog, digital, a brand that you've have used and had good experiences with? Part numbers for the tools I need from any other manufacturer besides Thexton maybe??? Thanks

 

Hi, I bought my Thexton tools from an ebay seller a couple years ago, they are kinda hard to come by and I will never give mine up! I hope you can find them on ebay! They came in two seperate sets, together it's everything I need along with my old autoxray ez-link scanner/code reader and analog dwellmeter and timing light I bought back in the 70's, I think the dwell meter came from sears and the analog dial allows me to see the m/s sweep up and down the scale as the ECU varies the solenoid pulse width. I bet you could use an oscilliscope as well! Idle doesn't change when I connect this dwell meter. I found on my buick 231 it helped to set the idle mixture dwell on the high end of the scale during idle b/c sometimes the CCCC would start "hunting" for some reason and would go full lean, the engine would die in that case. My M/S has a 1/8" travel and I set the lean/rich stops properly. I didn't have to do this on the 305V8 in my other gbody, just set up with the stop gauges and it's fine, didn't mess with the idle air bleed but did cut the idle mixture screw caps using a dremel grinder took the cap heads off in case I needed to make any idle mixture adjustments and of course hose out the needle passages. No adjustments were necessary once I slapped the carb back on the car, it has the original O2 sensor and the carb had never been off or rebuilt! Good luck with finding the tools, they're a must to have! Or, maybe carb guru Cliff Ruggles might have the tools, you could try him! cliffshighperformance dot com

 

I kept up a search in eBay for a few months and I managed to get the tools I needed. It's definetly possible. Good luck!!

 

I usually just make em.

Main one you need, looks like a rod about 5/32" or so dia, with a slot in the end maybe 1/16" wide; however thick the lean stop thing is. You can measure the hole in the casting that it has to go through and make it that OD. That will work on both the lean and the rich stops, as well as the idle mixture screws; except that the IM screws have basically no "authority" at all, so I usually just set em at about 6 - 7 turns out and forget em, then do all the idle tuning with the IAB.

I built a dwell meter some years ago, maybe 30 - 35, very simple circuit really. I think you can still get "automotive" DMMs that have that function, though.

 

I found and bought the Thexton 350 which is both the double d and the 4.5mm hex. Hope it works. Now I just need to settle on a decent dwell meter. There's a cheap, one-trick Actron meter on amazon I've been thinking about getting. I don think my DMM has the dwell function on it, unfortunately. Thanks for the help though.
