Can anyone recommend a shop to rebuild a Harmond & Collins Magneto. No spark. I filed the points but that did't help.
Try getting in touch with New England Motor Racing Supply (NEMRS). They may not do it in-house, but I'm sure they can point you in the right direction.
Bearing Burner, Recently I had a H & C Magneto gone through by Pat at Mason Racing Ignitions. He stocks NOS parts. Fast turn around and great service. He is in Schwenksville, PA, [610] 287-1511. Offy 220
Cool things about H&C mags for the flathead: A lot of critical parts are still available. The coil is the same basic part as the coils in S-1200 series Bendix aircraft magnetos. They are easy to find all over the country in used or new condition. The outlet insulators are the same as those on SB/SF series 4, 5, & 6 cylinder Bendix-Scintilla mags as found on many small 1940-1960 aircraft engines. The knurled aluminum nut is available n.o.s. as an SB/SF Bendix-Scintilla part (buy the unshielded part number which works with the exposed 7mm stainless stranded Packard cable). Bearings are the same sealed units as found on many late Bendix & Slick aircraft mags (but Bearing Engineering sells these for non-aircraft for about 2 dollars each, rather than $30-50 each (Don't buy an old aircraft unless you are rich or into pain). Capacitors are no biggie too (find one that fits the mag with .35 microfarad capacity). Words of caution: Don't screw with the magnet shaft or bearings unless you know what you are doing before you begin. They are retained by retaining rings that will ruin the magnet if you try to press it out without removing the rings first! The cast aluminum center & spokes supporting the magnets are very prone to damage from the least bit of careless behavior. The magnets are also very difficult to recharge without the correct diameter 8-pole fixture and a VERY high-output 2-pole magnet charger (can be fabbed with two L-shaped black iron blocks with 4 poles, each machined to fit over the O.D. of the magnet array). Also, though someone makes new splines to adapt the mag to the flathead which allow for timing adjustments, they are kind of expensive parts to begin with, and old ones are very rare. Don't lose 'em. The distributor finger is also a VERY delicate part. BE CAREFUL when the crab cap is off. Hope this helps, DIG? -Andy
