I went with the tecumseh because I didn't get much of a response to my question about which one is better. Hah! I think I ordered the Tec before anyone commented. I considered the Mikuni clone, but I have another Tec carb that I had played with, and zero experience with Mikuni. The carb did bolt up to the billet adaptor, but I think the Mikuni would have also bolted up to it. I did go with the Tec clone that has the adjuster screw in the bowl, so I hope to finally get the bike going soon. I'm waiting on my tank to come in. My other Tec clone (on my HS40) was awesome! I had it running well in no time.
After I posted that question, I did a mental flash back to when I was tuning that Mik. I had several questions, and it wasn't as straight forward as any of the Tec carbs where you just turn a couple screws. Over time, I'd forgotten that angst.
Once I did figure it out, and got the right jet combinations, and most importantly got the right depth on the needle valve, the carb was simply great. No further tuning required, never needed fuel enrichment, started second pull, and the response was phenomenal. But yeah, it took awhile to get there. You definitely need a couple of different pilot and main jets laying around.
Thanks for the answers. Eric, I doubt you lack any of the skill required for this job, ya lazy bones. :laugh: And I know David could do it with his eyes closed.
The next time I do a flat head, and it warrants more carb, I'll go with a Mic clone again. To the OP, you might ask 125ccCrazy what parts he recommends, as I bought one of his engines, and that thing was a hot rod.
