    Power Products AH58 Tillotson carb

    Anybody know of a later model Tillotson carb that will replace my HL 135B ? I heard that maybe an HL 166B would work. Any input would be helpful. Thanks !

    Ed, I had a HL189 on my WB580 and it was really too small (venturi was less than 1" ) to do the job. The 166B is pretty small with a .625 venturi. If you are hell-bent on sticking with HL, give EC a call at 615-446-6807 and ask for their advice and let them know application, and any modifications done to the engine.

    I went with a China copy from Vince at Classic Kart Shop who sells a 1" bore carb. It idles better than the Tilly's and I've had good luck with it so far as have many others. I did have to cannibalize the choke detent spring and slug to use the choke without a cable, but in hindsite, I didn't need the choke at all.

    Here is the carb.

    Here is the bike/engine I used it on. 580, with modified 820 reeds/cage, intake/stuffer.

    HL 306B, .750 venturi 1.005 throttle bore, has the choke, EC has them. Is the AH58 a kart engine or saw motor, saw motor intake manifold is small, you would want to increase the inlet size to 1 inch to take advantage of the larger carburetor.

    Ya gotta love 2 cycle power plants.

    I've been using a HL-239b .750 venturi carb on a 141cc case reed engine with good success. These are used on big Solo brand chainsaws.

    Amazing mini you've created there Dave. I had no idea there are clone Tilly HL series carbs being produced now.

    Thanks, I did a build thread on it a year ago. Louie Figone and a couple of other vintage kart guys recommended the clone Tilly as a possible replacement for what became an anemic HL after the engine modifications.

    Ed, a couple of years ago, I didn't know anything. Louie took time out of his busy schedule to hold my hand through rebuild and tuning, from crank modification for the PTO bearing, to rod needle bearings, to spark advance. I should have mentioned him above in my earlier answer.

    They aren't so intimidating now, and are far simpler than the Tecumseh four cycles. The HL189 I referred to as being too small for the modified 580 was perfect on my Clinton A400. That bike now sports a stock 58 exhaust, is much quieter, and the engine likes the back pressure even more than my neighbors.

    There is more that I don't know, than what I do know on these vintage two strokes.
