Thanks, everyone for the ideas. I went with a fairly thick piece of 1/4" brass bent into an L and soldered a 3/8" length of brass tubing to it to secure the cable housing. It is bolted thru the top engine mount lug hole. I particularly like the last suggestion. Since I already have the 1/4"...

I rebuilt my K&B3.5 powerhead. Any suggestions on break-in? Fuel, needle settings? Also, as far as prop balancers go, does the magnetic one from TopFlight work OK? I have a new Prather 215 to start out. Thx, Jon

I set up my radio box as per the instructions. How much steering throw should I end up with? On full rates, it doesn't look like it have a whole lot, but maybe it's more than I think. Is anyone running the K&B with the 5/8" transom spacer as suggested in the instructions--how is it running? I...

Can someone please post a picture and/or description of a throttle linkage cable clamp for this engine? I am thinking of just making an L-shape piece of brass with a short piece of brass tubing soldered on top fastened with a 4-40 bolt/nut thru the upper crankcase mounting hole. Or should I...

Thanks. I returned the venturi to the left-hand side. Do you know if the venturi needle is supposed to shut all the way and turn more than 1.5 turns on the stem? Jon

I've looked and blown thru the venturi. Doesn't appear to be any obstructions in there. When I close the needle as far as it goes (1.5 turns) I can still blow into the jet fairly easy. I have taken it apart, the jet hole was pointing directly down the center of the venturi barrel, so I put it...

Danny, I didn't get the instructions and I didn't see the specs on K&B website. I don't think they are making this model anymore, looks like they will bring back the rear drum induction model. As for HP, you could probably assume it would be similar to the 3.5SS o/b because they have pretty...

I picked up a K&B 3.5 IB on ebay. I think it is #8912. It has never been run and is in very good shape. I reversed the crankcase configuration to put the muffler on the back side in order to allow the venturi to be rotated up instead of on its side. (See picture.) Will the engine run in...

I should've mentioned that I bolted on a newer K&B 3.5 that I had in storage, with a K&B black carb. I will post a picture of the engine w/ perry carb. The barrel opens up in the opposite direction, from the top, so it is a "pull" to open rather than a "push." Since I don't know much about...

Hi, I bought a used tunnel hull that came into the local hobby shop and it has a K&B 3.5 OB. See attached pic. It looks like it is an older model K&B by the look of the con-rod and head, but it is in good shape. It has a Perry carb on it. Anybody know if the Perry used to be standard...
